.SH NAME

terminfo \- terminal capability data base
|
|
.SH SYNOPSIS
|
|
\*d/*/*
|
|
.SH DESCRIPTION
|
|
.I Terminfo
|
|
is a data base describing terminals, used by screen-oriented programs such as
|
|
.IR vi (1),
|
|
.IR rogue (1)
|
|
and
|
|
.IR ncurses (3X).
|
|
.I 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.
|
|
.PP
|
|
Entries in
|
|
.I terminfo
|
|
consist of a number of `,' separated fields.
|
|
White space after each `,' is ignored.
|
|
The first entry for each terminal gives the names which are known for the
|
|
terminal, separated 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.
|
|
.PP
|
|
Terminal names (except for the last, verbose entry) should
|
|
be chosen using the following conventions.
|
|
The particular piece of hardware making up the terminal should
|
|
have a root name chosen, thus ``hp2621''.
|
|
This name should not contain hyphens, except that synonyms may
|
|
be chosen that do not conflict with other names.
|
|
Modes that the hardware can be in, or user preferences, should
|
|
be indicated by appending a hyphen and an indicator of the mode.
|
|
Thus, a vt100 in 132 column mode would be vt100-w.
|
|
The following suffixes should be used where possible:

\fBSuffix Meaning Example\fP
|
|
-w Wide mode (more than 80 columns) vt100-w
|
|
-am With auto. margins (usually default) vt100-am
|
|
-nam Without automatic margins vt100-nam
|
|
-\fIn\fP Number of lines on the screen aaa-60
|
|
-na No arrow keys (leave them in local) c100-na
|
|
-\fIn\fPp Number of pages of memory c100-4p
|
|
-rv Reverse video c100-rv
|
|
.TE
|
|
.SH CAPABILITIES
|
|
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.
|
|
The i.code is the two letter internal code used in the compiled database,
|
|
and always corresponds to the old
|
|
.B termcap
|
|
capability name.
|
|
.P
|
|
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
|
|
.B caps
|
|
to line up nicely.
|
|
Whenever possible, names are chosen to be the same as or similar to
|
|
the ANSI X3.64-1979 standard. Semantics are also intended to match
|
|
those of the specification.
|
|
.TP
|
|
(P)
|
|
indicates that padding may be specified
|
|
.TP
|
|
(G)
|
|
indicates that the string is passed through tparm with
|
|
parms as given (#\fIi\fP).
|
|
.TP
|
|
(*)
|
|
indicates that padding may be based on the number of
|
|
lines affected
|
|
.TP
|
|
(#\d\fIi\fP\u)
|
|
indicates the \fIi\fP\uth\d parameter.

Entries may continue onto multiple lines by placing white space at

|
|
Capabilities in
|
|
.I terminfo
|
|
are of three types:
|
|
Boolean capabilities which indicate that the terminal has
|
|
some particular feature, numeric capabilities giving the size of the terminal
|
|
or the size of particular delays, and string
|
|
capabilities, which give a sequence which can be used to perform particular
|
|
terminal operations.
|
|
.PP
|
|
.B Types of Capabilities
|
|
.PP
|
|
All capabilities have names. For instance, the fact that
|
|
the Concept has
|
|
.I "automatic margins"
|
|
(i.e., an automatic return and linefeed
|
|
when the end of a line is reached) is indicated by the capability \fBam\fR.
|
|
Hence the description of the Concept includes \fBam\fR.
|
|
Numeric capabilities are followed by the character `#' and then the value.
|
|
Thus \fBcols\fR, which indicates the number of columns the terminal has,
|
|
gives the value `80' for the Concept.
|
|
.PP
|
|
Finally, string valued capabilities, such as \fBel\fR (clear to end of line
|
|
sequence) are given by the two-character code, an `=', and then a string
|
|
ending at the next following `,'. A delay in milliseconds may appear
|
|
anywhere in such a capability, enclosed in $<..> brackets,
|
|
as in \fBel\fP=\eEK$<3>,
|
|
and padding characters are supplied by
|
|
.I tputs
|
|
to provide this delay.
|
|
The delay can be either a number, e.g., `20', or a number followed by
|
|
an `*', i.e., `3*'. 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
|
|
.IR lines
|
|
affected.
|
|
This is always one unless the terminal has \fBxenl\fP and the software uses it.)
|
|
When a `*' is specified, it is sometimes useful to give a delay of the form
|
|
`3.5' to specify a delay per unit to tenths of milliseconds.
|
|
(Only one decimal place is allowed.)
|
|
.PP
|
|
A number of escape sequences are provided in the string valued capabilities
|
|
for easy encoding of characters there. Both \fB\eE\fR and \fB\ee\fR
|
|
map to an \s-1ESCAPE\s0 character,
|
|
\fB^x\fR maps to a control-x for any appropriate x, and the sequences
|
|
\fB\en \el \er \et \eb \ef \es\fR give
|
|
a newline, linefeed, return, tab, backspace, formfeed, and space.
|
|
Other escapes include \e^ for ^, \e\e for \e, \e, for comma, \e: for :,
|
|
and \e0 for null.
|
|
(\e0 will produce \e200, which does not terminate a string but behaves
|
|
as a null character on most terminals.)
|
|
Finally, characters may be given as three octal digits after a \fB\e\fR.
|
|
.PP
|
|
Sometimes individual capabilities must be commented out.
|
|
To do this, put a period before the capability name.
|
|
For example, see the second
|
|
.B ind
|
|
in the example above.

|
|
.B Preparing Descriptions
|
|
.PP
|
|
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
|
|
.I terminfo
|
|
and to build up a description gradually, using partial descriptions
|
|
with
|
|
.I 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
|
|
.I terminfo
|
|
file to describe it
|
|
or bugs in the screen-handling code of the test program.
|
|
To easily test a new terminal description you can set the environment variable
|
|
TERMINFO to a pathname of a directory containing the
|
|
compiled description you are working
|
|
on and programs will look there rather than in
|
|
.IR \*d .
|
|
To get the padding for insert line right (if the terminal manufacturer
|
|
did not document it) a severe test is to edit /etc/passwd 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.
|
|
.PP
|
|
.B Basic Capabilities
|
|
.PP
|
|
The number of columns on each line for the terminal is given by the
|
|
\fBcols\fR numeric capability. If the terminal is a \s-1CRT\s0, then the
|
|
number of lines on the screen is given by the \fBlines\fR capability.
|
|
If the terminal wraps around to the beginning of the next line when
|
|
it reaches the right margin, then it should have the \fBam\fR capability.
|
|
If the terminal can clear its screen, leaving the cursor in the home
|
|
position, then this is given by the \fBclear\fR string capability.
|
|
If the terminal overstrikes
|
|
(rather than clearing a position when a character is struck over)
|
|
then it should have the \fBos\fR capability.
|
|
If the terminal is a printing terminal, with no soft copy unit,
|
|
give it both
|
|
.B hc
|
|
and
|
|
.BR os .
|
|
.RB ( os
|
|
applies to storage scope terminals, such as \s-1TEKTRONIX\s+1 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
|
|
.BR cr .
|
|
(Normally this will be carriage return, control M.)
|
|
If there is a code to produce an audible signal (bell, beep, etc)
|
|
give this as
|
|
.BR bel .
|
|
.PP
|
|
If there is a code to move the cursor one position to the left
|
|
(such as backspace) that capability should be given as
|
|
.BR cub1 .
|
|
Similarly, codes to move to the right, up, and down should be
|
|
given as
|
|
.BR cuf1 ,
|
|
.BR cuu1 ,
|
|
and
|
|
.BR cud1 .
|
|
These local cursor motions should not alter the text they pass over,
|
|
for example, you would not normally use `\fBcuf1\fP=\ ' because the
|
|
space would erase the character moved over.
|
|
.PP
|
|
A very important point here is that the local cursor motions encoded
|
|
in
|
|
.I terminfo
|
|
are undefined at the left and top edges of a \s-1CRT\s0 terminal.
|
|
Programs should never attempt to backspace around the left edge,
|
|
unless
|
|
.B 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
|
|
.B ind
|
|
(index) string.
|
|
.PP
|
|
To scroll text down, a program goes to the top left corner
|
|
of the screen and sends the
|
|
.B ri
|
|
(reverse index) string.
|
|
The strings
|
|
.B ind
|
|
and
|
|
.B ri
|
|
are undefined when not on their respective corners of the screen.
|
|
.PP
|
|
Parameterized versions of the scrolling sequences are
|
|
.B indn
|
|
and
|
|
.B rin
|
|
which have the same semantics as
|
|
.B ind
|
|
and
|
|
.B ri
|
|
except that they take one parameter, and scroll that many lines.
|
|
They are also undefined except at the appropriate edge of the screen.
|
|
.PP
|
|
The \fBam\fR 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
|
|
.B cuf1
|
|
from the last column.
|
|
The only local motion which is defined from the left edge is if
|
|
.B bw
|
|
is given, then a
|
|
.B cub1
|
|
from the left edge will move to the right edge of the previous row.
|
|
If
|
|
.B 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
|
|
.I terminfo
|
|
file usually assumes that this is on; i.e., \fBam\fR.
|
|
If the terminal has a command which moves to the first column of the next
|
|
line, that command can be given as
|
|
.B nel
|
|
(newline).
|
|
It does not matter if the command clears the remainder of the current line,
|
|
so if the terminal has no
|
|
.B cr
|
|
and
|
|
.B lf
|
|
it may still be possible to craft a working
|
|
.B nel
|
|
out of one or both of them.
|
|
.PP
|
|
These capabilities suffice to describe hardcopy and \*(lqglass-tty\*(rq terminals.
|
|

.PP

.B Parameterized Strings
|
|
.PP
|
|
Cursor addressing and other strings requiring parameters
|
|
in the terminal are described by a
|
|
parameterized string capability, with
|
|
.IR printf (3S)
|
|
like escapes \fB%x\fR in it.
|
|
For example, to address the cursor, the
|
|
.B 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
|
|
.BR mrcup .
|
|
.PP
|
|
The parameter mechanism uses a stack and special \fB%\fP 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.
|
|
.PP
|
|
The \fB%\fR encodings have the following meanings:
|
|
.PP
|
|
.DT
|
|
.nf
|
|
.ta .5i 1.5i
|

%s print pop() gives %s

%p[1-9] push ith parm
|
|
%P[a-z] set variable [a-z] to pop()
|
|
%g[a-z] get variable [a-z] and push it
|
|
%'c' char constant c
|
|
%{nn} integer constant nn
|
|
|
|
%+ %- %* %/ %m
|
|
arithmetic (%m is mod): push(pop() op pop())
|
|
%& %| %^ bit operations: push(pop() op pop())
|
|
%= %> %< logical operations: push(pop() op pop())
|
|
%! %~ unary operations push(op pop())
|
|
%i add 1 to first two parms (for ANSI terminals)
|
|
|
|
%? expr %t thenpart %e elsepart %;
|
|
if-then-else, %e elsepart is optional.
|
|
else-if's are possible ala Algol 68:
|
|
%? c\d1\u %t b\d1\u %e c\d2\u %t b\d2\u %e c\d3\u %t b\d3\u %e c\d4\u %t b\d4\u %e %;
|
|
\s+1 c\di\u are conditions, b\di\u are bodies.
|
|
.fi
|
|
.PP
|
|
Binary operations are in postfix form with the operands in the usual order.
|
|
That is, to get x-5 one would use "%gx%{5}%-".
|
|
.PP
|
|
Consider the HP2645, which, to get to row 3 and column 12, needs
|
|
to be sent \eE&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 \fBcup\fR capability is \*(lqcup=6\eE&%p2%2dc%p1%2dY\*(rq.
|
|
.PP
|
|
The Microterm \s-1ACT-IV\s0 needs the current row and column sent
|
|
preceded by a \fB^T\fR, with the row and column simply encoded in binary,
|
|
\*(lqcup=^T%p1%c%p2%c\*(rq.
|
|
Terminals which use \*(lq%c\*(rq need to be able to
|
|
backspace the cursor (\fBcub1\fR),
|
|
and to move the cursor up one line on the screen (\fBcuu1\fR).
|
|
This is necessary because it is not always safe to transmit \fB\en\fR
|
|
\fB^D\fR and \fB\er\fR, as the system may change or discard them.
|
|
(The library routines dealing with terminfo set tty modes so that
|
|
tabs are never expanded, so \et is safe to send.
|
|
This turns out to be essential for the Ann Arbor 4080.)
|
|
.PP
|
|
A final example is the \s-1LSI ADM\s0-3a, which uses row and column
|
|
offset by a blank character, thus \*(lqcup=\eE=%p1%' '%+%c%p2%' '%+%c\*(rq.
|
|
After sending `\eE=', 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.
|
|
.PP
|
|
If the terminal has row or column absolute cursor addressing,
|
|
these can be given as single parameter capabilities
|
|
.B hpa
|
|
(horizontal position absolute)
|
|
and
|
|
.B 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
|
|
.B cup .
|
|
If there are parameterized local motions (e.g., move
|
|
.I n
|
|
spaces to the right) these can be given as
|
|
.BR cud ,
|
|
.BR cub ,
|
|
.BR cuf ,
|
|
and
|
|
.BR cuu
|
|
with a single parameter indicating how many spaces to move.
|
|
These are primarily useful if the terminal does not have
|
|
.BR cup ,
|
|
such as the \s-1TEKTRONIX\s+1 4025.
|
|
.PP
|
|
.B Cursor Motions
|
|
.PP
|
|
If the terminal has a fast way to home the cursor
|
|
(to very upper left corner of screen) then this can be given as
|
|
\fBhome\fR; similarly a fast way of getting to the lower left-hand corner
|
|
can be given as \fBll\fR; this may involve going up with \fBcuu1\fR
|
|
from the home position,
|
|
but a program should never do this itself (unless \fBll\fR 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 corner of the screen, not of memory.
|
|
(Thus, the \eEH sequence on HP terminals cannot be used for
|
|
.BR home .)
|
|
.PP
|
|
.B Area Clears
|
|
.PP
|
|
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 \fBel\fR.
|
|
If the terminal can clear from the current position to the end of the
|
|
display, then this should be given as \fBed\fR.
|
|
\fBEd\fR 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
|
|
.B ed
|
|
is not available.)
|
|
.PP
|
|
.B Insert/delete line
|
|
.PP
|
|
If the terminal can open a new blank line before the line where the cursor
|
|
is, this should be given as \fBil1\fR; 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 \fBdl1\fR; this is done only from the first position on
|
|
the line to be deleted.
|
|
Versions of
|
|
.B il1
|
|
and
|
|
.B dl1
|
|
which take a single parameter and insert or delete that many lines can
|
|
be given as
|
|
.B il
|
|
and
|
|
.BR dl .
|
|
If the terminal has a settable scrolling region (like the vt100)
|
|
the command to set this can be described with the
|
|
.B 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
|
|
this command \- the
|
|
.B sc
|
|
and
|
|
.B rc
|
|
(save and restore cursor) commands are also useful.
|
|
Inserting lines at the top or bottom of the screen can also be
|
|
done using
|
|
.B ri
|
|
or
|
|
.B ind
|
|
on many terminals without a true insert/delete line,
|
|
and is often faster even on terminals with those features.
|
|
.PP
|
|
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
|
|
.BR wind .
|
|
The four parameters are the starting and ending lines in memory
|
|
and the starting and ending columns in memory, in that order.
|
|
.PP
|
|
If the terminal can retain display memory above, then the
|
|
\fBda\fR capability should be given; if display memory can be retained
|
|
below, then \fBdb\fR should be given. These indicate
|
|
that deleting a line or scrolling may bring non-blank lines up from below
|
|
or that scrolling back with \fBri\fR may bring down non-blank lines.
|
|
.PP
|
|
.B Insert/Delete Character
|
|
.PP
|
|
There are two basic kinds of intelligent terminals with respect to
|
|
insert/delete character which can be described using
|
|
.I terminfo.
|
|
The most common insert/delete character operations affect only the characters
|
|
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 \*(lqabc\ \ \ \ def\*(rq using local
|
|
cursor motions (not spaces) between the \*(lqabc\*(rq and the \*(lqdef\*(rq.
|
|
Then position the cursor before the \*(lqabc\*(rq 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 \*(lqabc\*(rq
|
|
shifts over to the \*(lqdef\*(rq which then move together around the end of the
|
|
current line and onto the next as you insert, you have the second type of
|
|
terminal, and should give the capability \fBin\fR, which stands for
|
|
\*(lqinsert null\*(rq.
|
|
While these are two logically separate attributes (one line vs. multiline
|
|
insert mode, and special treatment of untyped spaces) we have seen no
|
|
terminals whose insert mode cannot be described with the single attribute.
|
|
.PP
|
|
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 \fBsmir\fR the sequence to get into insert mode.
|
|
Give as \fBrmir\fR the sequence to leave insert mode.
|
|
Now give as \fBich1\fR any sequence needed to be sent just before sending
|
|
the character to be inserted. Most terminals with a true insert mode
|
|
will not give \fBich1\fR; 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 \fBich1\fP.
|
|
Do not give both unless the terminal actually requires both
|
|
to be used in combination.)
|
|
If post insert padding is needed, give this as a number of milliseconds
|
|
in \fBip\fR (a string option). Any other sequence which may need to be
|
|
sent after an insert of a single character may also be given in \fBip\fR.
|
|
If your terminal needs both to be placed into an `insert mode' and
|
|
a special code to precede each inserted character, then both
|
|
.BR smir / rmir
|
|
and
|
|
.B ich1
|
|
can be given, and both will be used.
|
|
The
|
|
.B ich
|
|
capability, with one parameter,
|
|
.IR n ,
|
|
will repeat the effects of
|
|
.B ich1
|
|
.I n
|
|
times.

|
.PP
|
|
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 \fBmir\fR to speed up inserting
|
|
in this case. Omitting \fBmir\fR will affect only speed. Some terminals
|
|
(notably Datamedia's) must not have \fBmir\fR because of the way their
|
|
insert mode works.
|
|
.PP
|
|
Finally, you can specify
|
|
.B dch1
|
|
to delete a single character,
|
|
.B dch
|
|
with one parameter,
|
|
.IR n ,
|
|
to delete
|
|
.I n characters,

and delete mode by giving \fBsmdc\fR and \fBrmdc\fR
|

to enter and exit delete mode (any mode the terminal needs to be placed
|

in for
|
|
.B dch1
|
|
to work).

A command to erase
|
|
.I n
|

characters (equivalent to outputting
|

blanks without moving the cursor)
|

can be given as

.B ech

with one parameter.

.B "Highlighting, Underlining, and Visible Bells"
|
|
.PP
|
|
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
|
|
\f2standout mode\fR,
|
|
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 \fBsmso\fR and \fBrmso\fR, 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 \fBxmc\fR should be given to tell how many spaces are left.
|
|
.PP
|
|
Codes to begin underlining and end underlining can be given as \fBsmul\fR
|
|
and \fBrmul\fR 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 \fBuc\fR.
|
|
.PP
|
|
Other capabilities to enter various highlighting modes include
|
|
.B blink
|
|
(blinking)
|
|
.B bold
|
|
(bold or extra bright)
|
|
.B dim
|
|
(dim or half-bright)
|
|
.B invis
|
|
(blanking or invisible text)
|
|
.B prot
|
|
(protected)
|
|
.B rev
|

(reverse video)
|
|
.B sgr0
|
|
(turn off
|
|
.I all
|
|
attribute modes)
|
|
.B smacs
|
|
(enter alternate character set mode)
|
|
and
|
|
.B rmacs
|
|
(exit alternate character set mode).
|
|
Turning on any of these modes singly may or may not turn off other modes.
|
|
.PP
|
|
If there is a sequence to set arbitrary combinations of modes,
|
|
this should be given as
|
|
.B sgr
|
|
(set attributes),
|
|
taking 9 parameters.
|
|
Each parameter is either 0 or 1, 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
|
|
.BR sgr ,
|
|
only those for which corresponding separate attribute commands exist.
|
|
.PP
|
|
Terminals with the ``magic cookie'' glitch
|
|
.RB ( 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
|
|
.B msgr
|
|
capability, asserting that it is safe to move in standout mode, is present.
|
|
.PP
|
|
If the terminal has
|
|
a way of flashing the screen to indicate an error quietly (a bell replacement)
|
|
then this can be given as \fBflash\fR; it must not move the cursor.
|
|
.PP
|
|
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
|
|
.BR cvvis .
|
|
If there is a way to make the cursor completely invisible, give that as
|
|
.BR civis .
|
|
The capability
|
|
.BR cnorm
|
|
should be given which undoes the effects of both of these modes.
|
|
.PP
|
|
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 \fBsmcup\fR and \fBrmcup\fR.
|
|
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 cursor addressing, a one screen-sized window must be fixed into
|
|
the terminal for cursor addressing to work properly.
|
|
This is also used for the \s-1TEKTRONIX\s+1 4025,
|
|
where
|
|
.B smcup
|
|
sets the command character to be the one used by terminfo.
|
|
.PP
|
|
If your terminal correctly generates underlined characters
|
|
(with no special codes needed)
|
|
even though it does not overstrike,
|
|
then you should give the capability \fBul\fR.
|
|
If overstrikes are erasable with a blank,
|
|
then this should be indicated by giving \fBeo\fR.
|
|
.PP
|
|
.B Keypad
|
|
.PP
|
|
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 \fBsmkx\fR and \fBrmkx\fR.
|
|
Otherwise 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 \fBkcub1, kcuf1, kcuu1, kcud1,
|
|
\fRand\fB khome\fR respectively.
|
|
If there are function keys such as f0, f1, ..., f10, the codes they send
|
|
can be given as \fBkf0, kf1, ..., kf10\fR.
|
|
If these keys have labels other than the default f0 through f10, the labels
|
|
can be given as \fBlf0, lf1, ..., lf10\fR.
|
|
The codes transmitted by certain other special keys can be given:
|
|
.B kll
|
|
(home down),
|
|
.B kbs
|
|
(backspace),
|
|
.B ktbc
|
|
(clear all tabs),
|
|
.B kctab
|
|
(clear the tab stop in this column),
|
|
.B kclr
|
|
(clear screen or erase key),
|
|
.B kdch1
|
|
(delete character),
|
|
.B kdl1
|
|
(delete line),
|
|
.B krmir
|

.B kel

.B ked

.B kich1

.B kil1

.B knp
|
|
(next page),
|

.B kpp
|

.B kind
|
|
(scroll forward/down),
|
|
.B kri
|
|
(scroll backward/up),
|
|
.B 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
|
|
.BR ka1 ,
|
|
.BR ka3 ,
|
|
.BR kb2 ,
|
|
.BR kc1 ,
|
|
and
|
|
.BR kc3 .

These keys are useful when the effects of a 3 by 3 directional pad are needed.

.PP
|
|
.B Tabs and Initialization
|
|
.PP
|
|
If the terminal has hardware tabs, the command to advance to the next
|
|
tab stop can be given as
|
|
.B ht
|
|
(usually control I).
|
|
A ``backtab'' command which moves leftward to the next tab stop can
|
|
be given as
|
|
.BR cbt .
|
|
By convention, if the teletype modes indicate that tabs are being
|
|
expanded by the computer rather than being sent to the terminal,
|
|
programs should not use
|
|
.B ht
|
|
or
|
|
.B 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
|
|
.I n
|
|
spaces when the terminal is powered up,
|
|
the numeric parameter
|
|
.B it
|
|
is given, showing the number of spaces the tabs are set to.
|
|
This is normally used by the
|
|
.IR 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 nonvolatile memory,
|
|
the terminfo description can assume that they are properly set.
|
|
.PP
|
|
Other capabilities
|
|
include
|
|
.BR is1 ,
|
|
.BR is2 ,
|
|
and
|
|
.BR is3 ,
|
|
initialization strings for the terminal,
|
|
.BR iprog ,
|
|
the path name of a program to be run to initialize the terminal,
|
|
and \fBif\fR, the name of a file containing long initialization 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
|
|
.IR tset
|
|
program, each time the user logs in.
|
|
They will be printed in the following order:
|
|
.BR is1 ;
|
|
.BR is2 ;
|
|
setting tabs using
|
|
.B tbc
|
|
and
|
|
.BR hts ;
|
|
.BR if ;
|
|
running the program
|
|
.BR iprog ;
|
|
and finally
|
|
.BR is3 .
|
|
Most initialization is done with
|
|
.BR is2 .
|
|
Special terminal modes can be set up without duplicating strings
|
|
by putting the common sequences in
|
|
.B is2
|
|
and special cases in
|
|
.B is1
|
|
and
|
|
.BR is3 .
|
|
A pair of sequences that does a harder reset from a totally unknown state
|
|
can be analogously given as
|
|
.BR rs1 ,
|
|
.BR rs2 ,
|
|
.BR rf ,
|
|
and
|
|
.BR rs3 ,
|
|
analogous to
|
|
.B is2
|
|
and
|
|
.BR if .
|
|
These strings are output by the
|
|
.IR reset
|
|
program, which is used when the terminal gets into a wedged state.
|
|
Commands are normally placed in
|
|
.B rs2
|
|
and
|
|
.B 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
|
|
.BR 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.
|
|
.PP
|
|
If there are commands to set and clear tab stops, they can be given as
|
|
.B tbc
|
|
(clear all tab stops)
|
|
and
|
|
.B 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
|
|
.B is2
|
|
or
|
|
.BR if .

Delays

.PP
|
|
Certain capabilities control padding in the teletype driver.
|
|
These are primarily needed by hard copy terminals, and are used
|
|
by the
|
|
.IR tset
|
|
program to set teletype modes appropriately.
|
|
Delays embedded in the capabilities
|
|
.BR cr ,
|
|
.BR ind ,
|
|
.BR cub1 ,
|
|
.BR ff ,
|

and
|
|
.B tab
|
|
will cause the appropriate delay bits to be set in the teletype driver.
|
|
If
|
|
.B pb
|
|
(padding baud rate)
|
|
is given,
|
|
these values can be ignored at baud rates below the value of
|
|
.BR pb .
|

.PP
|
|
.B Miscellaneous
|
|
.PP
|
|
If the terminal requires other than a null (zero) character as a pad,
|
|
then this can be given as \fBpad\fR.
|
|
Only the first character of the
|
|
.B pad
|
|
string is used.
|
|
.PP
|
|
If the terminal has an extra ``status line'' that is not normally
|
|
used by software, this fact can be indicated.
|
|
If the status line is viewed as an extra line below the bottom line,
|
|
into which one can cursor address normally
|
|
(such as the Heathkit h19's 25th line, or the 24th line of a vt100
|
|
which is set to a 23-line scrolling region),
|
|
the capability
|
|
.B hs
|
|
should be given.
|
|
Special strings to go to the beginning of the status
|
|
line and to return from the status line can be given as
|
|
.B tsl
|
|
and
|
|
.BR fsl .
|
|
.RB ( fsl
|
|
must leave the cursor position in the same place it was before
|
|
.BR tsl .
|
|
If necessary, the
|
|
.B sc
|
|
and
|
|
.B rc
|
|
strings can be included in
|
|
.B tsl
|
|
and
|
|
.B fsl
|
|
to get this effect.)
|
|
The parameter
|
|
.B tsl
|
|
takes one parameter, which is the column number of the status line
|
|
the cursor is to be moved to.
|
|
If escape sequences and other special commands, such as tab, work
|
|
while in the status line, the flag
|
|
.B eslok
|
|
can be given.
|
|
A string which turns off the status line (or otherwise erases its
|
|
contents) should be given as
|
|
.BR dsl .
|
|
If the terminal has commands to save and restore the position of the cursor,
|
|
give them as
|
|
.B sc
|
|
and
|
|
.BR rc .
|
|
The status line is normally assumed to be the same width as the rest
|
|
of the screen, e.g.,
|
|
.BR cols .
|
|
If the status line is a different width (possibly because the terminal
|
|
does not allow an entire line to be loaded) the width, in columns,
|
|
can be indicated with the numeric parameter
|
|
.BR wsl .
|
|
.PP
|
|
If the terminal can move up or down half a line,
|
|
this can be indicated with
|
|
.B hu
|
|
(half-line up)
|
|
and
|
|
.B hd
|
|
(half-line down).
|
|
This is primarily useful for superscripts and subscripts on hardcopy terminals.
|
|
If a hardcopy terminal can eject to the next page (form feed), give this as
|
|
.B ff
|
|
(usually control L).
|
|
.PP
|
|
If there is a command to repeat a given character a given number of
|
|
times (to save time transmitting a large number of identical characters)
|
|
this can be indicated with the parameterized string
|
|
.BR 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'.
|
|
.PP
|
|
If the terminal has a settable command character, such as the \s-1TEKTRONIX\s+1 4025,
|
|
this can be indicated with
|
|
.BR cmdch .
|
|
A prototype command character is chosen which is used in all capabilities.
|
|
This character is given in the
|
|
.B cmdch
|
|
capability to identify it.
|
|
The following convention is supported on some UNIX systems:
|
|
The environment is to be searched for a
|
|
.B CC
|
|
variable, and if found, all
|
|
occurrences of the prototype character are replaced with the character
|

in the environment variable.

not be transmitted.

If the terminal has a ``meta key'' which acts as a shift key,

setting the 8th bit of any character transmitted, this fact can

.BR mc4 :
|

turn off the printer, and
|
|
.BR mc5 :

turn on the printer.

When the printer is on, all text sent to the terminal will be sent

It is undefined whether the text is also displayed on the terminal screen
|

A variation
|

takes one parameter, and leaves the printer on for as many characters

The parameter should not exceed 255.

All text, including

Strings to program function keys can be given as

Each of these strings takes two parameters: the function key number to

Function key numbers out of this range may program undefined keys in

a terminal dependent manner.

The difference between the capabilities is that
|

.B pfkey

such as the Concept and vt100,
|
|
should indicate \fBxenl\fR.
|
|
.PP
|
|
If
|
|
.B el
|
|
is required to get rid of standout
|
|
(instead of merely writing normal text on top of it),
|
|
\fBxhp\fP should be given.
|
|
.PP
|
|
Teleray terminals, where tabs turn all characters moved over to blanks,
|
|
should indicate \fBxt\fR (destructive tabs).
|
|
Note: the variable indicating this is now `dest_tabs_magic_smso'; in
|
|
older versions, it was teleray_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 Beehive Superbee, which is unable to correctly transmit the escape
|
|
or control C characters, has
|
|
.BR 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'.
|
|
.PP
|
|
Other specific terminal problems may be corrected by adding more
|
|
capabilities of the form \fBx\fIx\fR.

.B Similar Terminals
|
|
.PP
|
|
If there are two very similar terminals,
|
|
one can be defined as being just like the other with certain exceptions.
|
|
The string capability \fBuse\fR can be given
|
|
with the name of the similar terminal.
|
|
The capabilities given before
|
|
.B use
|
|
override those in the terminal type invoked by
|
|
.BR use .
|
|
A capability can be cancelled by placing \fBxx@\fR to the left of the
|
|
capability definition, where xx is the capability.
|
|
For example, the entry
|
|
.PP
|
|
2621-nl, smkx@, rmkx@, use=2621,
|
|
.PP
|
|
defines a 2621-nl that does not have the \fBsmkx\fR or \fBrmkx\fR 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.
