NAME
       terminfo - terminal capability data base

SYNOPSIS
       /usr/share/misc/terminfo/*/*

DESCRIPTION
       Terminfo  is  a data base describing terminals, used by screen-oriented
       programs such as nvi(1), rogue(1) and  libraries  such  as  curses(3X).
       Terminfo describes terminals by giving a set of capabilities which they
       have, by specifying how to perform screen operations, and by specifying
       padding requirements and initialization sequences.

       Entries	in  terminfo  consist  of  a  sequence of `,' separated fields
       (embedded commas may be escaped with a  backslash or notated as	\072).
       White  space  after  the `,' separator is ignored.  The first entry for
       each terminal gives the names which are known for the  terminal,  sepa-
       rated  by  `|'  characters.   The  first  name given is the most common
       abbreviation for the terminal, the last name given  should  be  a  long
       name  fully  identifying the terminal, and all others are understood as
       synonyms for the terminal name.	All names but the last	should	be  in
       lower  case and contain no blanks; the last name may well contain upper
       case and blanks for readability.

       Terminal names (except for the last, verbose entry)  should  be	chosen
       using the following conventions.  The particular piece of hardware mak-
       ing up the terminal should have a root  name,  thus  ``hp2621''.   This
       name should not contain hyphens.  Modes that the hardware can be in, or
       user preferences, should be indicated by appending a hyphen and a  mode
       suffix.	 Thus,	a vt100 in 132 column mode would be vt100-w.  The fol-
       lowing suffixes should be used where possible:


	    Suffix		    Meaning		      Example
	    -nn      Number of lines on the screen	      aaa-60
	    -np      Number of pages of memory		      c100-4p
	    -am      With automargins (usually the default)   vt100-am
	    -m	     Mono mode; suppress color		      ansi-m
	    -mc      Magic cookie; spaces when highlighting   wy30-mc
	    -na      No arrow keys (leave them in local)      c100-na
	    -nam     Without automatic margins		      vt100-nam
	    -nl      No status line			      att4415-nl
	    -ns      No status line			      hp2626-ns
	    -rv      Reverse video			      c100-rv
	    -s	     Enable status line 		      vt100-s
	    -vb      Use visible bell instead of beep	      wy370-vb
	    -w	     Wide mode (> 80 columns, usually 132)    vt100-w

       For more on terminal naming conventions, see the term(7) manual page.

   Capabilities
       The following is a complete table of the  capabilities  included  in  a
       terminfo  description  block  and available to terminfo-using code.  In
       each line of the table,

       The variable is the name by  which  the	programmer  (at  the  terminfo
       level) accesses the capability.

       The  capname is the short name used in the text of the database, and is
       used by a person updating the database.	 Whenever  possible,  capnames
       are chosen to be the same as or similar to the ANSI X3.64-1979 standard
       (now superseded by  ECMA-48,  which  uses  identical  or  very  similar
       names).	 Semantics  are also intended to match those of the specifica-
       tion.

       The termcap code is the old termcap capability name (some  capabilities
       are new, and have names which termcap did not originate).

       Capability  names have no hard length limit, but an informal limit of 5
       characters has been adopted to keep them short and to allow the tabs in
       the source file Caps to line up nicely.

       Finally,  the description field attempts to convey the semantics of the
       capability.  You may find some codes in the description field:

       (P)    indicates that padding may be specified

       #[1-9] in the description field indicates that  the  string  is	passed
	      through tparm with parms as given (#i).

       (P*)   indicates  that  padding may vary in proportion to the number of
	      lines affected

       (#i)   indicates the ith parameter.


       These are the boolean capabilities:

       Entries may continue onto multiple lines by placing white space at  the
       beginning  of  each line except the first.  Comments may be included on
       lines beginning with ``#''.  Capabilities  in  terminfo	are  of  three
       types:  Boolean	capabilities which indicate that the terminal has some
       particular feature, numeric capabilities giving the size of the	termi-
       nal  or	the  size of particular delays, and string capabilities, which
       give a sequence which can be used to perform particular terminal opera-
       tions.


   Types of Capabilities
       All capabilities have names.  For instance, the fact that ANSI-standard
       terminals have automatic margins (i.e., an automatic return  and  line-
       feed  when the end of a line is reached) is indicated by the capability
       am.  Hence the description of ansi includes am.	 Numeric  capabilities
       are  followed  by  the  character  `#' and then a positive value.  Thus
       cols, which indicates the number of columns the terminal has, gives the
       value  `80' for ansi.  Values for numeric capabilities may be specified
       in decimal, octal or hexadecimal, using the C programming language con-
       ventions (e.g., 255, 0377 and 0xff or 0xFF).

       Finally,  string  valued capabilities, such as el (clear to end of line
       sequence) are given by the two-character  code,	an  `=',  and  then  a
       string ending at the next following `,'.

       A number of escape sequences are provided in the string valued capabil-
       ities for easy encoding of characters there.  Both \E and \e map to  an
       ESCAPE character, ^x maps to a control-x for any appropriate x, and the
       sequences \n \l \r \t \b \f \s give a newline, line-feed, return,  tab,
       backspace,  form-feed,  and  space.  Other escapes include \^ for ^, \\
       for \, \, for comma, \: for :, and \0 for null.	(\0 will produce \200,
       which  does  not  terminate a string but behaves as a null character on
       most terminals, providing CS7 is specified.   See  stty(1).)   Finally,
       characters may be given as three octal digits after a \.

       A  delay  in  milliseconds  may appear anywhere in a string capability,
       enclosed in $<..> brackets, as in el=\EK$<5>,  and  padding  characters
       are  supplied by tputs to provide this delay.  The delay must be a num-
       ber with at most one decimal place of precision; it may be followed  by
       suffixes `*' or '/' or both.  A `*' indicates that the padding required
       is proportional to the number of lines affected by the  operation,  and
       the  amount  given  is the per-affected-unit padding required.  (In the
       case of insert character, the factor  is  still	the  number  of  lines
       affected.)   Normally,  padding	is  advisory if the device has the xon
       capability; it is used  for  cost  computation  but  does  not  trigger
       delays.	 A  `/'  suffix  indicates  that  the padding is mandatory and
       forces a delay of the given number of milliseconds even on devices  for
       which xon is present to indicate flow control.

       Sometimes  individual  capabilities must be commented out.  To do this,
       put a period before the capability name.  For example, see  the	second
       ind in the example above.


   Fetching Compiled Descriptions
       If  the	environment variable TERMINFO is set, it is interpreted as the
       pathname of a directory containing the  compiled  description  you  are
       working on.  Only that directory is searched.

       If TERMINFO is not set, the ncurses version of the terminfo reader code
       will instead look in  the  directory  $HOME/.terminfo  for  a  compiled
       description.   If it fails to find one there, and the environment vari-
       able TERMINFO_DIRS is set, it will interpret the contents of that vari-
       able as a list of colon- separated directories to be searched (an empty
       entry is interpreted as a command to search  /usr/share/misc/terminfo).
       If no description is found in any of the TERMINFO_DIRS directories, the
       fetch fails.

       If neither TERMINFO nor TERMINFO_DIRS is set, the last place tried will
       be the system terminfo directory, /usr/share/misc/terminfo.

       (Neither  the  $HOME/.terminfo lookups nor TERMINFO_DIRS extensions are
       supported under stock System V terminfo/curses.)


   Preparing Descriptions
       We now outline how to prepare  descriptions  of	terminals.   The  most
       effective  way  to  prepare  a terminal description is by imitating the
       description of a similar  terminal  in  terminfo  and  to  build  up  a
       description gradually, using partial descriptions with vi or some other
       screen-oriented program to check that they are correct.	Be aware  that
       a  very	unusual terminal may expose deficiencies in the ability of the
       terminfo file to describe it or bugs in the screen-handling code of the
       test program.

       To  get the padding for insert line right (if the terminal manufacturer
       did not document it) a severe test is to edit  a  large	file  at  9600
       baud, delete 16 or so lines from the middle of the screen, then hit the
       `u' key several times quickly.  If the terminal messes up, more padding
       is usually needed.  A similar test can be used for insert character.


   Basic Capabilities
       The  number  of	columns  on each line for the terminal is given by the
       cols numeric capability.  If the terminal is a CRT, then the number  of
       lines  on the screen is given by the lines capability.  If the terminal
       wraps around to the beginning of the next  line	when  it  reaches  the
       right  margin,  then it should have the am capability.  If the terminal
       can clear its screen, leaving the cursor in  the  home  position,  then
       this  is  given	by the clear string capability.  If the terminal over-
       strikes (rather than clearing a position when  a  character  is	struck
       over)  then  it	should	have  the os capability.  If the terminal is a
       printing terminal, with no soft copy unit, give it both hc and os.  (os
       applies	to  storage scope terminals, such as TEKTRONIX 4010 series, as
       well as hard copy and APL terminals.)  If there is a code to  move  the
       cursor to the left edge of the current row, give this as cr.  (Normally
       this will be carriage return, control M.)  If there is a code  to  pro-
       duce an audible signal (bell, beep, etc) give this as bel.

       If there is a code to move the cursor one position to the left (such as
       backspace) that capability should be given as cub1.   Similarly,  codes
       to  move  to the right, up, and down should be given as cuf1, cuu1, and
       cud1.  These local cursor motions should not alter the text  they  pass
       over,  for  example,  you  would  not normally use `cuf1= ' because the
       space would erase the character moved over.

       A very important point here is that the local cursor motions encoded in
       terminfo  are  undefined  at  the left and top edges of a CRT terminal.
       Programs should never attempt to backspace around the left edge, unless
       bw  is given, and never attempt to go up locally off the top.  In order
       to scroll text up, a program will go to the bottom left corner  of  the
       screen and send the ind (index) string.

       To  scroll  text  down,	a  program  goes to the top left corner of the
       screen and sends the ri (reverse index) string.	The strings ind and ri
       are undefined when not on their respective corners of the screen.

       Parameterized  versions	of  the  scrolling  sequences are indn and rin
       which have the same semantics as ind and ri except that they  take  one
       parameter,  and scroll that many lines.	They are also undefined except
       at the appropriate edge of the screen.

       The am capability tells whether the cursor sticks at the right edge  of
       the  screen when text is output, but this does not necessarily apply to
       a cuf1 from the last column.  The only local motion  which  is  defined
       from  the  left	edge is if bw is given, then a cub1 from the left edge
       will move to the right edge of the previous row.  If bw is  not	given,
       the  effect  is undefined.  This is useful for drawing a box around the
       edge of the screen, for example.  If the terminal has switch selectable
       automatic  margins,  the terminfo file usually assumes that this is on;
       i.e., am.  If the terminal has a command which moves to the first  col-
       umn  of	the next line, that command can be given as nel (newline).  It
       does not matter if the command clears  the  remainder  of  the  current
       line,  so  if the terminal has no cr and lf it may still be possible to
       craft a working nel out of one or both of them.

       These capabilities suffice to describe hard-copy and "glass-tty" termi-
       nals.  Thus the model 33 teletype is described as

     33|tty33|tty|model 33 teletype,
     bel=^G, cols#72, cr=^M, cud1=^J, hc, ind=^J, os,

       while the Lear Siegler ADM-3 is described as

     adm3|3|lsi adm3,
     am, bel=^G, clear=^Z, cols#80, cr=^M, cub1=^H, cud1=^J,
     ind=^J, lines#24,


   Parameterized Strings
       Cursor  addressing and other strings requiring parameters in the termi-
       nal are described by a parameterized string capability, with printf(3S)
       like  escapes  %x  in  it.  For example, to address the cursor, the cup
       capability is given, using  two	parameters:  the  row  and  column  to
       address	to.  (Rows and columns are numbered from zero and refer to the
       physical screen visible to the user, not to any unseen memory.)	If the
       terminal  has  memory relative cursor addressing, that can be indicated
       by mrcup.

       The parameter mechanism uses a stack and special % codes to  manipulate
       it.   Typically	a  sequence  will  push one of the parameters onto the
       stack and then print it in some format.	Often more complex  operations
       are necessary.

       The % encodings have the following meanings:

	    %%	      outputs `%'
	    %[[:]flags][width[.precision]][doxXs]
		      as in printf, flags are [-+#] and space
	    %c	      print pop() like %c in printf()
	    %s	      print pop() like %s in printf()

	    %p[1-9]   push i'th parm
	    %P[a-z]   set dynamic variable [a-z] to pop()
	    %g[a-z]   get dynamic variable [a-z] and push it
	    %P[A-Z]   set static variable [a-z] to pop()
	    %g[A-Z]   get static variable [a-z] and push it
	    %'c'      char constant c
	    %{nn}     integer constant nn
	    %l	      push strlen(pop)

	    %+ %- %* %/ %m
		      arithmetic (%m is mod): push(pop() op pop())
	    %& %| %^  bit operations: push(pop() op pop())
	    %= %> %<  logical operations: push(pop() op pop())
	    %A, %O    logical and & or operations (for conditionals)
	    %! %~     unary operations push(op pop())
	    %i	      add 1 to first two parameters (for ANSI terminals)

	    %? expr %t thenpart %e elsepart %;
		      if-then-else, %e elsepart is optional.
		      else-if's are possible a la Algol 68:
		      %? c1 %t b1 %e c2 %t b2 %e c3 %t b3 %e c4 %t b4 %e %;
		      ci are conditions, bi are bodies.

       Binary  operations  are	in postfix form with the operands in the usual
       order.  That is, to get x-5 one would use "%gx%{5}%-".  %P and %g vari-
       ables are persistent across escape-string evaluations.

       Consider  the HP2645, which, to get to row 3 and column 12, needs to be
       sent \E&a12c03Y padded for 6 milliseconds.  Note that the order of  the
       rows  and  columns  is  inverted  here, and that the row and column are
       printed	 as   two   digits.	Thus	its    cup    capability    is
       "cup=6\E&%p2%2dc%p1%2dY".

       The  Microterm ACT-IV needs the current row and column sent preceded by
       a  ^T,  with  the  row	and   column   simply	encoded   in   binary,
       "cup=^T%p1%c%p2%c".   Terminals	which  use  "%c"  need	to  be able to
       backspace the cursor (cub1), and to move the cursor up one line on  the
       screen  (cuu1).	 This  is  necessary  because it is not always safe to
       transmit \n ^D and \r, as the system may change or discard them.   (The
       library	routines  dealing with terminfo set tty modes so that tabs are
       never expanded, so \t is safe to send.  This turns out to be  essential
       for the Ann Arbor 4080.)

       A  final example is the LSI ADM-3a, which uses row and column offset by
       a blank character, thus "cup=\E=%p1%' '%+%c%p2%' '%+%c".  After sending
       `\E=',  this  pushes  the first parameter, pushes the ASCII value for a
       space (32), adds them (pushing the sum on the stack in place of the two
       previous  values) and outputs that value as a character.  Then the same
       is done for the second parameter.  More complex arithmetic is  possible
       using the stack.


   Cursor Motions
       If  the	terminal has a fast way to home the cursor (to very upper left
       corner of screen) then this can be given as home; similarly a fast  way
       of  getting  to the lower left-hand corner can be given as ll; this may
       involve going up with cuu1 from the home position, but a program should
       never do this itself (unless ll does) because it can make no assumption
       about the effect of moving up from the home position.   Note  that  the
       home  position is the same as addressing to (0,0): to the top left cor-
       ner of the screen, not of memory.  (Thus, the \EH sequence on HP termi-
       nals cannot be used for home.)

       If the terminal has row or column absolute cursor addressing, these can
       be given as single  parameter  capabilities  hpa  (horizontal  position
       absolute)  and  vpa  (vertical position absolute).  Sometimes these are
       shorter than the more general  two  parameter  sequence	(as  with  the
       hp2645)	and can be used in preference to cup.  If there are parameter-
       ized local motions (e.g., move n spaces to  the	right)	these  can  be
       given  as cud, cub, cuf, and cuu with a single parameter indicating how
       many spaces to move.  These are primarily useful if the	terminal  does
       not have cup, such as the TEKTRONIX 4025.

       If  the	terminal  needs to be in a special mode when running a program
       that uses these capabilities, the codes to enter and exit this mode can
       be  given as smcup and rmcup.  This arises, for example, from terminals
       like the Concept with more than one page of memory.   If  the  terminal
       has only memory relative cursor addressing and not screen relative cur-
       sor addressing, a one screen-sized window must be fixed into the termi-
       nal  for cursor addressing to work properly.  This is also used for the
       TEKTRONIX 4025, where smcup sets the command character to  be  the  one
       used  by  terminfo.   If the smcup sequence will not restore the screen
       after an rmcup sequence is output (to the  state  prior	to  outputting
       rmcup), specify nrrmc.


   Area Clears
       If  the	terminal can clear from the current position to the end of the
       line, leaving the cursor where it is, this should be given as  el.   If
       the  terminal  can  clear from the beginning of the line to the current
       position inclusive, leaving the cursor where  it  is,  this  should  be
       given  as  el1.	If the terminal can clear from the current position to
       the end of the display, then this should be given as ed.   Ed  is  only
       defined from the first column of a line.  (Thus, it can be simulated by
       a request to delete a large number of lines, if a true ed is not avail-
       able.)


   Insert/delete line and vertical motions
       If  the	terminal  can  open a new blank line before the line where the
       cursor is, this should be given as il1; this  is  done  only  from  the
       first  position	of  a  line.  The cursor must then appear on the newly
       blank line.  If the terminal can delete the line which  the  cursor  is
       on,  then this should be given as dl1; this is done only from the first
       position on the line to be deleted.  Versions of il1 and dl1 which take
       a single parameter and insert or delete that many lines can be given as
       il and dl.

       If the terminal has a settable scrolling region (like  the  vt100)  the
       command	to  set  this  can be described with the csr capability, which
       takes two parameters: the top and bottom lines of the scrolling region.
       The cursor position is, alas, undefined after using this command.

       It  is possible to get the effect of insert or delete line using csr on
       a properly chosen region; the sc and rc (save and restore cursor)  com-
       mands  may  be  useful for ensuring that your synthesized insert/delete
       string does not move the cursor.  (Note that  the  ncurses(3X)  library
       does   this   synthesis	 automatically,   so   you  need  not  compose
       insert/delete strings for an entry with csr).

       Yet another way to construct insert and delete might be to use a combi-
       nation  of  index  with the memory-lock feature found on some terminals
       (like the HP-700/90 series, which however also has insert/delete).

       Inserting lines at the top or bottom of the screen  can	also  be  done
       using  ri  or  ind on many terminals without a true insert/delete line,
       and is often faster even on terminals with those features.

       The boolean non_dest_scroll_region should be set if each scrolling win-
       dow  is	effectively a view port on a screen-sized canvas.  To test for
       this capability, create a scrolling region in the middle of the screen,
       write  something  to the bottom line, move the cursor to the top of the
       region, and do ri followed by dl1 or ind.  If the data scrolled off the
       bottom  of  the	region	by  the  ri re-appears, then scrolling is non-
       destructive.  System V and XSI Curses expect that ind,  ri,  indn,  and
       rin  will  simulate destructive scrolling; their documentation cautions
       you not to define csr unless this is true.  This curses	implementation
       is more liberal and will do explicit erases after scrolling if ndstr is
       defined.

       If the terminal has the ability to define a window as part  of  memory,
       which  all  commands  affect,  it  should be given as the parameterized
       string wind.  The four parameters are the starting and ending lines  in
       memory and the starting and ending columns in memory, in that order.

       If the terminal can retain display memory above, then the da capability
       should be given; if display memory  can	be  retained  below,  then  db
       should  be given.  These indicate that deleting a line or scrolling may
       bring non-blank lines up from below or that scrolling back with ri  may
       bring down non-blank lines.


   Insert/Delete Character
       There  are  two	basic  kinds  of intelligent terminals with respect to
       insert/delete character which can be  described	using  terminfo.   The
       most  common insert/delete character operations affect only the charac-
       ters on the current line and shift characters off the end of  the  line
       rigidly.  Other terminals, such as the Concept 100 and the Perkin Elmer
       Owl, make a distinction between typed and untyped blanks on the screen,
       shifting  upon  an  insert  or  delete  only to an untyped blank on the
       screen which is either eliminated, or expanded to two  untyped  blanks.
       You  can determine the kind of terminal you have by clearing the screen
       and then typing text separated by cursor  motions.   Type  "abc	  def"
       using  local  cursor  motions  (not  spaces)  between the "abc" and the
       "def".  Then position the cursor before the "abc" and put the  terminal
       in  insert  mode.   If typing characters causes the rest of the line to
       shift rigidly and characters to fall off the end,  then	your  terminal
       does  not  distinguish  between	blanks	and untyped positions.	If the
       "abc" shifts over to the "def" which then move together around the  end
       of  the current line and onto the next as you insert, you have the sec-
       ond type of terminal, and should give the capability in,  which	stands
       for  "insert  null".  While these are two logically separate attributes
       (one line versus multi-line  insert  mode,  and	special  treatment  of
       untyped	spaces)  we have seen no terminals whose insert mode cannot be
       described with the single attribute.

       Terminfo can describe both terminals which have	an  insert  mode,  and
       terminals  which send a simple sequence to open a blank position on the
       current line.  Give as smir the sequence to get into insert mode.  Give
       as  rmir  the  sequence	to  leave  insert  mode.  Now give as ich1 any
       sequence needed to be sent just before  sending	the  character	to  be
       inserted.   Most  terminals with a true insert mode will not give ich1;
       terminals which send a sequence to open a screen position  should  give
       it here.

       If  your  terminal has both, insert mode is usually preferable to ich1.
       Technically, you should not give  both  unless  the  terminal  actually
       requires  both to be used in combination.  Accordingly, some non-curses
       applications get confused if both are present; the symptom  is  doubled
       characters  in  an  update using insert.  This requirement is now rare;
       most ich sequences do not require previous smir, and most  smir	insert
       modes  do  not  require ich1 before each character.  Therefore, the new
       curses actually assumes this is the case and uses either  rmir/smir  or
       ich/ich1  as appropriate (but not both).  If you have to write an entry
       to be used under new curses for a terminal old  enough  to  need  both,
       include the rmir/smir sequences in ich1.

       If post insert padding is needed, give this as a number of milliseconds
       in ip (a string option).  Any other sequence which may need to be  sent
       after an insert of a single character may also be given in ip.  If your
       terminal needs both to be placed into an `insert mode'  and  a  special
       code  to  precede each inserted character, then both smir/rmir and ich1
       can be given, and both will be used.   The  ich	capability,  with  one
       parameter, n, will repeat the effects of ich1 n times.

       If  padding  is	necessary between characters typed while not in insert
       mode, give this as a number of milliseconds padding in rmp.

       It is occasionally necessary to move around while  in  insert  mode  to
       delete  characters  on the same line (e.g., if there is a tab after the
       insertion position).  If your terminal allows motion  while  in	insert
       mode  you  can  give  the  capability mir to speed up inserting in this
       case.  Omitting mir will affect only speed.   Some  terminals  (notably
       Datamedia's)  must  not	have  mir because of the way their insert mode
       works.

       Finally, you can specify dch1 to delete a single  character,  dch  with
       one  parameter,	n,  to	delete n characters, and delete mode by giving
       smdc and rmdc to enter and exit delete  mode  (any  mode  the  terminal
       needs to be placed in for dch1 to work).

       A  command  to  erase  n  characters (equivalent to outputting n blanks
       without moving the cursor) can be given as ech with one parameter.


   Highlighting, Underlining, and Visible Bells
       If your terminal has one or more kinds of display attributes, these can
       be  represented	in  a number of different ways.  You should choose one
       display form as standout mode,  representing  a	good,  high  contrast,
       easy-on-the-eyes,  format  for  highlighting  error  messages and other
       attention getters.  (If you have a choice,  reverse  video  plus  half-
       bright  is  good,  or reverse video alone.)  The sequences to enter and
       exit standout mode are given as smso and rmso,  respectively.   If  the
       code  to  change  into  or  out of standout mode leaves one or even two
       blank spaces on the screen, as the TVI 912 and Teleray  1061  do,  then
       xmc should be given to tell how many spaces are left.

       Codes to begin underlining and end underlining can be given as smul and
       rmul respectively.  If the terminal has a code to underline the current
       character  and  move  the  cursor  one  space to the right, such as the
       Microterm Mime, this can be given as uc.

       Other capabilities to enter various highlighting  modes	include  blink
       (blinking)  bold  (bold or extra bright) dim (dim or half-bright) invis
       (blanking or invisible text) prot (protected) rev (reverse video)  sgr0
       (turn  off  all	attribute  modes) smacs (enter alternate character set
       mode) and rmacs (exit alternate character set mode).  Turning on any of
       these modes singly may or may not turn off other modes.

       If  there  is  a  sequence to set arbitrary combinations of modes, this
       should be given as sgr (set attributes),  taking  9  parameters.   Each
       parameter  is either 0 or nonzero, as the corresponding attribute is on
       or off.	The 9 parameters are, in order: standout, underline,  reverse,
       blink,  dim,  bold,  blank,  protect, alternate character set.  Not all
       modes need be supported by sgr, only those for which corresponding sep-
       arate attribute commands exist.

       For example, the DEC vt220 supports most of the modes:


		 tparm parameter   attribute	escape sequence

		 none		   none 	\E[0m
		 p1		   standout	\E[0;1;7m
		 p2		   underline	\E[0;4m
		 p3		   reverse	\E[0;7m
		 p4		   blink	\E[0;5m
		 p5		   dim		not available
		 p6		   bold 	\E[0;1m
		 p7		   invis	\E[0;8m
		 p8		   protect	not used
		 p9		   altcharset	^O (off) ^N (on)

       We  begin each escape sequence by turning off any existing modes, since
       there is no quick way to determine whether they are  active.   Standout
       is  set up to be the combination of reverse and bold.  The vt220 termi-
       nal has a protect mode, though it is not commonly used in  sgr  because
       it  protects  characters  on  the screen from the host's erasures.  The
       altcharset mode also is different in  that  it  is  either  ^O  or  ^N,
       depending  on whether it is off or on.  If all modes are turned on, the
       resulting sequence is \E[0;1;4;5;7;8m^N.

       Some sequences are common to different modes.  For example, ;7 is  out-
       put  when  either  p1  or  p3  is  true, that is, if either standout or
       reverse modes are turned on.

       Writing out the above sequences, along with their dependencies yields


	       sequence    when to output     terminfo translation

	       \E[0	  always	      \E[0
	       ;1	  if p1 or p6	      %?%p1%p6%|%t;1%;
	       ;4	  if p2 	      %?%p2%|%t;4%;
	       ;5	  if p4 	      %?%p4%|%t;5%;
	       ;7	  if p1 or p3	      %?%p1%p3%|%t;7%;
	       ;8	  if p7 	      %?%p7%|%t;8%;
	       m	  always	      m

	       ^N or ^O   if p9 ^N, else ^O   %?%p9%t^N%e^O%;

       Putting this all together into the sgr sequence gives:

	   sgr=\E[0%?%p1%p6%|%t;1%;%?%p2%t;4%;%?%p1%p3%|%t;7%;
	       %?%p4%t;5%;%?%p7%t;8%;m%?%p9%t\016%e\017%;,

       Remember that if you specify sgr, you must also specify sgr0.

       Terminals with  the  ``magic  cookie''  glitch  (xmc)  deposit  special
       ``cookies''  when they receive mode-setting sequences, which affect the
       display algorithm rather than having extra  bits  for  each  character.
       Some  terminals, such as the HP 2621, automatically leave standout mode
       when they move to a new line or	the  cursor  is  addressed.   Programs
       using  standout mode should exit standout mode before moving the cursor
       or sending a newline, unless the msgr capability, asserting that it  is
       safe to move in standout mode, is present.

       If  the	terminal has a way of flashing the screen to indicate an error
       quietly (a bell replacement) then this can be given as flash;  it  must
       not move the cursor.

       If  the cursor needs to be made more visible than normal when it is not
       on the bottom line (to make, for example, a non-blinking underline into
       an  easier  to  find block or blinking underline) give this sequence as
       cvvis.  If there is a way to make the cursor completely invisible, give
       that  as  civis.  The capability cnorm should be given which undoes the
       effects of both of these modes.

       If your terminal correctly generates  underlined  characters  (with  no
       special	codes  needed)	even  though  it does not overstrike, then you
       should give the capability ul.  If  a  character  overstriking  another
       leaves  both  characters  on the screen, specify the capability os.  If
       overstrikes are erasable with a blank, then this should be indicated by
       giving eo.


   Keypad and Function Keys
       If  the	terminal  has  a keypad that transmits codes when the keys are
       pressed, this information can be given.	Note that it is  not  possible
       to handle terminals where the keypad only works in local (this applies,
       for example, to the unshifted HP 2621 keys).  If the keypad can be  set
       to transmit or not transmit, give these codes as smkx and rmkx.	Other-
       wise the keypad is assumed to always transmit.  The codes sent  by  the
       left  arrow,  right  arrow,  up arrow, down arrow, and home keys can be
       given as kcub1, kcuf1, kcuu1, kcud1, and khome respectively.  If  there
       are  function keys such as f0, f1, ..., f10, the codes they send can be
       given as kf0, kf1, ..., kf10.  If these keys have labels other than the
       default f0 through f10, the labels can be given as lf0, lf1, ..., lf10.
       The codes transmitted by certain other special keys can be  given:  kll
       (home  down),  kbs (backspace), ktbc (clear all tabs), kctab (clear the
       tab stop in this column), kclr  (clear  screen  or  erase  key),  kdch1
       (delete	character),  kdl1 (delete line), krmir (exit insert mode), kel
       (clear to end of line), ked (clear to end  of  screen),	kich1  (insert
       character  or  enter insert mode), kil1 (insert line), knp (next page),
       kpp (previous page), kind  (scroll  forward/down),  kri	(scroll  back-
       ward/up),  khts	(set  a tab stop in this column).  In addition, if the
       keypad has a 3 by 3 array of keys including the four  arrow  keys,  the
       other  five  keys  can  be given as ka1, ka3, kb2, kc1, and kc3.  These
       keys are useful when the effects of  a  3  by  3  directional  pad  are
       needed.

       Strings to program function keys can be given as pfkey, pfloc, and pfx.
       A string to program screen labels should be specified as pln.  Each  of
       these  strings takes two parameters: the function key number to program
       (from 0 to 10) and the string to program it with.  Function key numbers
       out  of	this  range may program undefined keys in a terminal dependent
       manner.	The difference between the capabilities is that  pfkey	causes
       pressing  the  given  key  to  be the same as the user typing the given
       string; pfloc causes the string to  be  executed  by  the  terminal  in
       local; and pfx causes the string to be transmitted to the computer.

       The  capabilities  nlab,  lw  and  lh define the number of programmable
       screen labels and their width and height.  If  there  are  commands  to
       turn  the  labels on and off, give them in smln and rmln.  smln is nor-
       mally output after one or more pln sequences  to  make  sure  that  the
       change becomes visible.


   Tabs and Initialization
       If  the	terminal has hardware tabs, the command to advance to the next
       tab stop can be given as ht (usually control I).  A  ``back-tab''  com-
       mand  which  moves  leftward  to the preceding tab stop can be given as
       cbt.  By convention, if the teletype modes indicate that tabs are being
       expanded  by  the computer rather than being sent to the terminal, pro-
       grams should not use ht or cbt even if they are present, since the user
       may  not have the tab stops properly set.  If the terminal has hardware
       tabs which are initially set every n spaces when the terminal  is  pow-
       ered  up, the numeric parameter it is given, showing the number of spa-
       ces the tabs are set to.  This is normally used by the tset command  to
       determine  whether  to  set  the  mode  for hardware tab expansion, and
       whether to set the tab stops.  If the terminal has tab stops  that  can
       be  saved  in  non-volatile memory, the terminfo description can assume
       that they are properly set.

       Other capabilities include is1, is2, and  is3,  initialization  strings
       for  the  terminal, iprog, the path name of a program to be run to ini-
       tialize the terminal, and if, the name of a file containing  long  ini-
       tialization  strings.   These  strings are expected to set the terminal
       into modes consistent with the rest of the terminfo description.   They
       are  normally sent to the terminal, by the init option of the tput pro-
       gram, each time the user logs in.  They will be printed in the  follow-
       ing  order:  run  the  program  iprog; output is1; is2; set the margins
       using mgc, smgl and smgr; set tabs using tbc and hts;  print  the  file
       if; and finally output is3.

       Most  initialization  is  done with is2.  Special terminal modes can be
       set up without duplicating strings by putting the common  sequences  in
       is2  and special cases in is1 and is3.  A pair of sequences that does a
       harder reset from a totally unknown state can be analogously  given  as
       rs1, rs2, rf, and rs3, analogous to is2 and if.	These strings are out-
       put by the reset program, which is used when the terminal gets  into  a
       wedged state.  Commands are normally placed in rs1, rs2 rs3 and rf only
       if they produce annoying effects on the screen and  are	not  necessary
       when  logging  in.   For  example,  the	command  to set the vt100 into
       80-column mode would normally be part of is2, but it causes an annoying
       glitch  of  the screen and is not normally needed since the terminal is
       usually already in 80 column mode.

       If there are commands to set and clear tab stops, they can be given  as
       tbc (clear all tab stops) and hts (set a tab stop in the current column
       of every row).  If a more complex sequence is needed to	set  the  tabs
       than can be described by this, the sequence can be placed in is2 or if.

   Delays and Padding
       Many older and slower terminals don't support either  XON/XOFF  or  DTR
       handshaking,  including	hard copy terminals and some very archaic CRTs
       (including, for example, DEC VT100s).  These may require padding  char-
       acters after certain cursor motions and screen changes.

       If the terminal uses xon/xoff handshaking for flow control (that is, it
       automatically emits ^S back to the host	when  its  input  buffers  are
       close  to  full),  set xon.  This capability suppresses the emission of
       padding.  You can also set it for memory-mapped console devices	effec-
       tively that don't have a speed limit.  Padding information should still
       be included so that routines can make better decisions  about  relative
       costs, but actual pad characters will not be transmitted.

       If pb (padding baud rate) is given, padding is suppressed at baud rates
       below the value of pb.  If the entry has no  padding  baud  rate,  then
       whether padding is emitted or not is completely controlled by xon.

       If  the	terminal requires other than a null (zero) character as a pad,
       then this can be given as pad.  Only the first  character  of  the  pad
       string is used.


   Status Lines
       Some  terminals	have an extra `status line' which is not normally used
       by software (and thus not counted in the terminal's lines  capability).

       The  simplest case is a status line which is cursor-addressable but not
       part of the main scrolling region on the screen; the Heathkit H19 has a
       status  line  of  this  kind,  as  would a 24-line VT100 with a 23-line
       scrolling region set up on initialization.  This situation is indicated
       by the hs capability.

       Some  terminals	with status lines need special sequences to access the
       status line.  These may be expressed as a string with single  parameter
       tsl  which takes the cursor to a given zero-origin column on the status
       line.  The capability fsl must return to the main-screen  cursor  posi-
       tions  before the last tsl.  You may need to embed the string values of
       sc (save cursor) and rc (restore cursor) in tsl and fsl	to  accomplish
       this.

       The  status  line is normally assumed to be the same width as the width
       of the terminal.  If this is  untrue,  you  can	specify  it  with  the
       numeric capability wsl.

       A command to erase or blank the status line may be specified as dsl.

       The  boolean  capability  eslok	specifies that escape sequences, tabs,
       etc., work ordinarily in the status line.

       The ncurses implementation does not yet use any of these  capabilities.
       They are documented here in case they ever become important.


   Line Graphics
       Many  terminals have alternate character sets useful for forms-drawing.
       Terminfo and curses build in support for the  drawing  characters  sup-
       ported  by  the VT100, with some characters from the AT&T 4410v1 added.
       This alternate character set may be specified by the acsc capability.

       The best way to define a new device's graphics set is to add  a	column
       to  a  copy of this table for your terminal, giving the character which
       (when emitted between smacs/rmacs switches) will  be  rendered  as  the
       corresponding graphic.  Then read off the VT100/your terminal character
       pairs right to left in sequence; these become the ACSC string.


   Color Handling
       Most color terminals are either `Tektronix-like'  or  `HP-like'.   Tek-
       tronix-like  terminals  have a predefined set of N colors (where N usu-
       ally 8), and can set character-cell foreground and  background  charac-
       ters  independently,  mixing  them  into N * N color-pairs.  On HP-like
       terminals, the use must set each color pair up  separately  (foreground
       and  background	are  not independently settable).  Up to M color-pairs
       may be set up from 2*M different colors.  ANSI-compatible terminals are
       Tektronix-like.

       Some basic color capabilities are independent of the color method.  The
       numeric capabilities colors and pairs specify the  maximum  numbers  of
       colors  and  color-pairs  that can be displayed simultaneously.	The op
       (original pair) string resets foreground and background colors to their
       default	values	for  the terminal.  The oc string resets all colors or
       color-pairs to their default values for the terminal.   Some  terminals
       (including many PC terminal emulators) erase screen areas with the cur-
       rent background color rather  than  the	power-up  default  background;
       these should have the boolean capability bce.

       To  change  the	current foreground or background color on a Tektronix-
       type terminal, use setaf (set ANSI  foreground)	and  setab  (set  ANSI
       background)  or setf (set foreground) and setb (set background).  These
       take one parameter, the color number.  The SVr4 documentation describes
       only  setaf/setab;  the	XPG4 draft says that "If the terminal supports
       ANSI escape sequences to set background and foreground, they should  be
       coded as setaf and setab, respectively.	If the terminal supports other
       escape sequences to set background and foreground, they should be coded
       as setf and setb, respectively.	The vidputs() function and the refresh
       functions use setaf and setab if they are defined."

       The setaf/setab and setf/setb capabilities take a single numeric  argu-
       ment  each.   Argument  values 0-7 are portably defined as follows (the
       middle column is the symbolic #define available in the header  for  the
       curses  or  ncurses  libraries).   The terminal hardware is free to map
       these as it likes, but the RGB  values  indicate  normal  locations  in
       color space.


		    Color	#define       Value	  RGB
		    black     COLOR_BLACK	0     0, 0, 0
		    red       COLOR_RED 	1     max,0,0
		    green     COLOR_GREEN	2     0,max,0
		    yellow    COLOR_YELLOW	3     max,max,0
		    blue      COLOR_BLUE	4     0,0,max
		    magenta   COLOR_MAGENTA	5     max,0,max
		    cyan      COLOR_CYAN	6     0,max,max
		    white     COLOR_WHITE	7     max,max,max

       On  an  HP-like terminal, use scp with a color-pair number parameter to
       set which color pair is current.

       On a Tektronix-like terminal, the capability  ccc  may  be  present  to
       indicate that colors can be modified.  If so, the initc capability will
       take a color number (0 to colors - 1)and three  more  parameters  which
       describe  the  color.   These  three parameters default to being inter-
       preted as RGB (Red, Green, Blue) values.  If the boolean capability hls
       is  present,  they  are	instead  as  HLS  (Hue, Lightness, Saturation)
       indices.  The ranges are terminal-dependent.

       On an HP-like terminal, initp may give  a  capability  for  changing  a
       color-pair  value.   It will take seven parameters; a color-pair number
       (0 to max_pairs - 1), and two triples describing first  background  and
       then foreground colors.	These parameters must be (Red, Green, Blue) or
       (Hue, Lightness, Saturation) depending on hls.

       On some color terminals, colors collide with highlights.  You can  reg-
       ister  these collisions with the ncv capability.  This is a bit-mask of
       attributes not to be used when colors are enabled.  The	correspondence
       with the attributes understood by curses is as follows:


			    Attribute	   Bit	 Decimal
			    A_STANDOUT	   0	 1
			    A_UNDERLINE    1	 2
			    A_REVERSE	   2	 4
			    A_BLINK	   3	 8
			    A_DIM	   4	 16
			    A_BOLD	   5	 32
			    A_INVIS	   6	 64
			    A_PROTECT	   7	 128
			    A_ALTCHARSET   8	 256

       For  example, on many IBM PC consoles, the underline attribute collides
       with the foreground color blue and is  not  available  in  color  mode.
       These should have an ncv capability of 2.

       SVr4  curses does nothing with ncv, ncurses recognizes it and optimizes
       the output in favor of colors.


   Miscellaneous
       If the terminal requires other than a null (zero) character as  a  pad,
       then  this  can	be  given as pad.  Only the first character of the pad
       string is used.	If the terminal does not have a pad character, specify
       npc.   Note that ncurses implements the termcap-compatible PC variable;
       though the application may set this value to  something	other  than  a
       null,  ncurses will test npc first and use napms if the terminal has no
       pad character.

       If the terminal can move up or down half a line, this can be  indicated
       with hu (half-line up) and hd (half-line down).	This is primarily use-
       ful for superscripts and subscripts on hard-copy terminals.  If a hard-
       copy  terminal  can eject to the next page (form feed), give this as ff
       (usually control L).

       If there is a command to repeat a given character  a  given  number  of
       times  (to  save  time transmitting a large number of identical charac-
       ters) this can be indicated with the  parameterized  string  rep.   The
       first  parameter  is the character to be repeated and the second is the
       number of times to repeat it.  Thus, tparm(repeat_char, 'x', 10) is the
       same as `xxxxxxxxxx'.

       If the terminal has a settable command character, such as the TEKTRONIX
       4025, this can be indicated with cmdch.	A prototype command  character
       is  chosen  which is used in all capabilities.  This character is given
       in the cmdch capability to identify it.	The  following	convention  is
       supported on some UNIX systems: The environment is to be searched for a
       CC variable, and if found, all occurrences of the  prototype  character
       are replaced with the character in the environment variable.

       Terminal  descriptions  that  do not represent a specific kind of known
       terminal, such as switch, dialup, patch, and  network,  should  include
       the  gn (generic) capability so that programs can complain that they do
       not know how to talk to the terminal.  (This capability does not  apply
       to  virtual  terminal  descriptions  for which the escape sequences are
       known.)

       If the terminal has a ``meta key'' which acts as a shift  key,  setting
       the  8th  bit  of any character transmitted, this fact can be indicated
       with km.  Otherwise, software will assume that the 8th  bit  is	parity
       and  it	will usually be cleared.  If strings exist to turn this ``meta
       mode'' on and off, they can be given as smm and rmm.

       If the terminal has more lines of memory than will fit on the screen at
       once,  the number of lines of memory can be indicated with lm.  A value
       of lm#0 indicates that the number of lines is not fixed, but that there
       is still more memory than fits on the screen.

       If  the terminal is one of those supported by the UNIX virtual terminal
       protocol, the terminal number can be given as vt.

       Media copy strings which control an auxiliary printer connected to  the
       terminal  can  be  given as mc0: print the contents of the screen, mc4:
       turn off the printer, and mc5: turn on the printer.  When  the  printer
       is  on,	all text sent to the terminal will be sent to the printer.  It
       is undefined whether the text is also displayed on the terminal	screen
       when  the  printer  is  on.   A variation mc5p takes one parameter, and
       leaves the printer on for as many characters as the value of the param-
       eter, then turns the printer off.  The parameter should not exceed 255.
       All text, including mc4, is transparently passed to the	printer  while
       an mc5p is in effect.


   Glitches and Braindamage
       Hazeltine  terminals, which do not allow `~' characters to be displayed
       should indicate hz.

       Terminals which ignore a line-feed immediately after an am  wrap,  such
       as the Concept and vt100, should indicate xenl.

       If  el  is  required  to get rid of standout (instead of merely writing
       normal text on top of it), xhp should be given.

       Teleray terminals, where tabs turn all characters moved over to blanks,
       should  indicate  xt (destructive tabs).  Note: the variable indicating
       this is now `dest_tabs_magic_smso'; in  older  versions,  it  was  tel-
       eray_glitch.  This glitch is also taken to mean that it is not possible
       to position the cursor on top of a  ``magic  cookie'',  that  to  erase
       standout  mode  it  is instead necessary to use delete and insert line.
       The ncurses implementation ignores this glitch.

       The Beehive Superbee, which is unable to correctly transmit the	escape
       or  control  C  characters, has xsb, indicating that the f1 key is used
       for escape and f2 for control C.  (Only	certain  Superbees  have  this
       problem,  depending on the ROM.)  Note that in older terminfo versions,
       this capability was called `beehive_glitch'; it is now  `no_esc_ctl_c'.

       Other  specific terminal problems may be corrected by adding more capa-
       bilities of the form xx.


   Similar Terminals
       If there are two very similar  terminals,  one  (the  variant)  can  be
       defined	as  being  just  like the other (the base) with certain excep-
       tions.  In the definition of the variant, the string capability use can
       be  given  with	the name of the base terminal.	The capabilities given
       before use override those in the base type named by use.  If there  are
       multiple  use capabilities, they are merged in reverse order.  That is,
       the rightmost use reference is processed first, then  the  one  to  its
       left,  and  so forth.  Capabilities given explicitly in the entry over-
       ride those brought in by use references.

       A capability can be canceled by placing xx@ to the left of the use ref-
       erence  that  imports it, where xx is the capability.  For example, the
       entry

		   2621-nl, smkx@, rmkx@, use=2621,

       defines a 2621-nl that does not have the smkx or rmkx capabilities, and
       hence  does  not  turn  on the function key labels when in visual mode.
       This is useful for different modes for a  terminal,  or	for  different
       user preferences.


   Pitfalls of Long Entries
       Long  terminfo  entries are unlikely to be a problem; to date, no entry
       has even approached terminfo's 4K string-table maximum.	Unfortunately,
       the  termcap  translations are much more strictly limited (to 1K), thus
       termcap translations of long terminfo entries can cause problems.

       The man pages for 4.3BSD and older versions of tgetent()  instruct  the
       user  to  allocate  a  1K buffer for the termcap entry.	The entry gets
       null-terminated by the termcap library, so that makes the maximum  safe
       length  for  a  termcap entry 1k-1 (1023) bytes.  Depending on what the
       application and the termcap library being used does, and where  in  the
       termcap file the terminal type that tgetent() is searching for is, sev-
       eral bad things can happen.

       Some termcap libraries print a warning message or exit if they find  an
       entry  that's longer than 1023 bytes; others don't; others truncate the
       entries to 1023 bytes.  Some application programs  allocate  more  than
       the recommended 1K for the termcap entry; others don't.

       Each  termcap  entry has two important sizes associated with it: before
       "tc" expansion, and after "tc" expansion.  "tc" is the capability  that
       tacks on another termcap entry to the end of the current one, to add on
       its capabilities.  If a termcap entry doesn't use the "tc"  capability,
       then of course the two lengths are the same.

       The  "before tc expansion" length is the most important one, because it
       affects more than just users of that particular terminal.  This is  the
       length  of the entry as it exists in /etc/termcap, minus the backslash-
       newline pairs, which tgetent() strips out while reading it.  Some term-
       cap  libraries strip off the final newline, too (GNU termcap does not).
       Now suppose:

       *    a termcap entry before expansion is more than 1023 bytes long,

       *    and the application has only allocated a 1k buffer,

       *    and the termcap library (like the one in BSD/OS 1.1 and GNU) reads
	    the whole entry into the buffer, no matter what its length, to see
	    if it's the entry it wants,

       *    and tgetent() is searching for a terminal type that either is  the
	    long  entry,  appears in the termcap file after the long entry, or
	    doesn't appear in the file at all (so that tgetent() has to search
	    the whole termcap file).

       Then  tgetent()	will overwrite memory, perhaps its stack, and probably
       core dump the program.  Programs like telnet are particularly  vulnera-
       ble;  modern telnets pass along values like the terminal type automati-
       cally.  The results are almost as undesirable with a  termcap  library,
       like  SunOS  4.1.3 and Ultrix 4.4, that prints warning messages when it
       reads an overly long termcap entry.  If	a  termcap  library  truncates
       long  entries,  like  OSF/1  3.0,  it  is immune to dying here but will
       return incorrect data for the terminal.

       The "after tc expansion" length will  have  a  similar  effect  to  the
       above, but only for people who actually set TERM to that terminal type,
       since tgetent() only does "tc" expansion once it's found  the  terminal
       type it was looking for, not while searching.

       In  summary,  a termcap entry that is longer than 1023 bytes can cause,
       on various combinations of termcap libraries and applications,  a  core
       dump,  warnings,  or incorrect operation.  If it's too long even before
       "tc" expansion, it will have this effect even for users of  some  other
       terminal  types	and  users whose TERM variable does not have a termcap
       entry.

       When in -C (translate to termcap) mode, the ncurses  implementation  of
       tic(1)  issues  warning	messages  when	the pre-tc length of a termcap
       translation is too long.  The -c (check) option	also  checks  resolved
       (after tc expansion) lengths.

   Binary Compatibility
       It  is  not  wise  to  count  on portability of binary terminfo entries
       between commercial UNIX versions.  The problem is  that	there  are  at
       least  two  versions  of  terminfo (under HP-UX and AIX) which diverged
       from System V terminfo after SVr1, and have added  extension  capabili-
       ties  to the string table that (in the binary format) collide with Sys-
       tem V and XSI Curses extensions.

EXTENSIONS
       Some SVr4 curses implementations,  and  all  previous  to  SVr4,  don't
       interpret the %A and %O operators in parameter strings.

       SVr4/XPG4  do  not  specify  whether msgr licenses movement while in an
       alternate-character-set mode (such modes may, among other  things,  map
       CR and NL to characters that don't trigger local motions).  The ncurses
       implementation ignores msgr in ALTCHARSET mode.	This raises the possi-
       bility  that  an XPG4 implementation making the opposite interpretation
       may need terminfo entries made for ncurses to have msgr turned off.

       The ncurses library handles insert-character and insert-character modes
       in  a  slightly	non-standard way to get better update efficiency.  See
       the Insert/Delete Character subsection above.

       The parameter substitutions for set_clock  and  display_clock  are  not
       documented  in  SVr4 or the XSI Curses standard.  They are deduced from
       the documentation for the AT&T 505 terminal.

       Be careful assigning the kmous capability.  The ncurses wants to inter-
       pret  it  as  KEY_MOUSE,  for use by terminals and emulators like xterm
       that  can  return  mouse-tracking  information  in  the	keyboard-input
       stream.

       Different  commercial  ports  of  terminfo and curses support different
       subsets of the XSI Curses standard and (in some cases) different exten-
       sion sets.  Here is a summary, accurate as of October 1995:

       SVR4, Solaris, ncurses -- These support all SVr4 capabilities.

       SGI  --	Supports  the  SVr4 set, adds one undocumented extended string
       capability (set_pglen).

       SVr1, Ultrix -- These support a restricted subset of terminfo capabili-
       ties.   The  booleans  end  with xon_xoff; the numerics with width_sta-
       tus_line; and the strings with prtr_non.

       HP/UX  --  Supports  the  SVr1  subset,	plus  the  SVr[234]   numerics
       num_labels,  label_height,  label_width,  plus function keys 11 through
       63, plus plab_norm, label_on, and  label_off,  plus  some  incompatible
       extensions in the string table.

       AIX -- Supports the SVr1 subset, plus function keys 11 through 63, plus
       a number of incompatible string table extensions.

       OSF -- Supports both the SVr4 set and the AIX extensions.
