Standout and Appearance Modes
=============================
"Appearance modes" are modifications to the ways characters are
displayed. Typical appearance modes include reverse video, dim, bright,
blinking, underlined, invisible, and alternate character set. Each
kind of terminal supports various among these, or perhaps none.
For each type of terminal, one appearance mode or combination of
them that looks good for highlighted text is chosen as the "standout
mode". The capabilities `so' and `se' say how to enter and leave
standout mode. Programs that use appearance modes only to highlight
some text generally use the standout mode so that they can work on as
many terminals as possible. Use of specific appearance modes other
than "underlined" and "alternate character set" is rare.
Terminals that implement appearance modes fall into two general
classes as to how they do it.
In some terminals, the presence or absence of any appearance mode is
recorded separately for each character position. In these terminals,
each graphic character written is given the appearance modes current at
the time it is written, and keeps those modes until it is erased or
overwritten. There are special commands to turn the appearance modes on
or off for characters to be written in the future.
In other terminals, the change of appearance modes is represented by
a marker that belongs to a certain screen position but affects all
following screen positions until the next marker. These markers are
traditionally called "magic cookies".
The same capabilities (`so', `se', `mb' and so on) for turning
appearance modes on and off are used for both magic-cookie terminals
and per-character terminals. On magic cookie terminals, these give the
commands to write the magic cookies. On per-character terminals, they
change the current modes that affect future output and erasure. Some
simple applications can use these commands without knowing whether or
not they work by means of cookies.
However, a program that maintains and updates a display needs to know
whether the terminal uses magic cookies, and exactly what their effect
is. This information comes from the `sg' capability.
The `sg' capability is a numeric capability whose presence indicates
that the terminal uses magic cookies for appearance modes. Its value is
the number of character positions that a magic cookie occupies. Usually
the cookie occupies one or more character positions on the screen, and
these character positions are displayed as blank, but in some terminals
the cookie has zero width.
The `sg' capability describes both the magic cookie to turn standout
on and the cookie to turn it off. This makes the assumption that both
kinds of cookie have the same width on the screen. If that is not true,
the narrower cookie must be "widened" with spaces until it has the same
width as the other.
On some magic cookie terminals, each line always starts with normal
display; in other words, the scope of a magic cookie never extends over
more than one line. But on other terminals, one magic cookie affects
all the lines below it unless explicitly canceled. Termcap does not
define any way to distinguish these two ways magic cookies can work.
To be safe, it is best to put a cookie at the beginning of each line.
On some per-character terminals, standout mode or other appearance
modes may be canceled by moving the cursor. On others, moving the
cursor has no effect on the state of the appearance modes. The latter
class of terminals are given the flag capability `ms' ("can move in
standout"). All programs that might have occasion to move the cursor
while appearance modes are turned on must check for this flag; if it is
not present, they should reset appearance modes to normal before doing
cursor motion.
A program that has turned on only standout mode should use `se' to
reset the standout mode to normal. A program that has turned on only
alternate character set mode should use `ae' to return it to normal. If
it is possible that any other appearance modes are turned on, use the
`me' capability to return them to normal.
Note that the commands to turn on one appearance mode, including `so'
and `mb' ... `mr', if used while some other appearance modes are turned
on, may combine the two modes on some terminals but may turn off the
mode previously enabled on other terminals. This is because some
terminals do not have a command to set or clear one appearance mode
without changing the others. Programs should not attempt to use
appearance modes in combination except with `sa', and when switching
from one single mode to another should always turn off the previously
enabled mode and then turn on the new desired mode.
On some old terminals, the `so' and `se' commands may be the same
command, which has the effect of turning standout on if it is off, or
off it is on. It is therefore risky for a program to output extra `se'
commands for good measure. Fortunately, all these terminals are
obsolete.
Programs that update displays in which standout-text may be replaced
with non-standout text must check for the `xs' flag. In a per-character
terminal, this flag says that the only way to remove standout once
written is to clear that portion of the line with the `ce' string or
something even more powerful (*note Clearing::.); just writing new
characters at those screen positions will not change the modes in
effect there. In a magic cookie terminal, `xs' says that the only way
to remove a cookie is to clear a portion of the line that includes the
cookie; writing a different cookie at the same position does not work.
Such programs must also check for the `xt' flag, which means that the
terminal is a Teleray 1061. On this terminal it is impossible to
position the cursor at the front of a magic cookie, so the only two
ways to remove a cookie are (1) to delete the line it is on or (2) to
position the cursor at least one character before it (possibly on a
previous line) and output the `se' string, which on these terminals
finds and removes the next `so' magic cookie on the screen. (It may
also be possible to remove a cookie which is not at the beginning of a
line by clearing that line.) The `xt' capability also has implications
for the use of tab characters, but in that regard it is obsolete (*Note
Cursor Motion::).
String of commands to enter standout mode.
String of commands to leave standout mode.
Numeric capability, the width on the screen of the magic cookie.
This capability is absent in terminals that record appearance modes
character by character.
Flag whose presence means that it is safe to move the cursor while
the appearance modes are not in the normal state. If this flag is
absent, programs should always reset the appearance modes to
normal before moving the cursor.
Flag whose presence means that the only way to reset appearance
modes already on the screen is to clear to end of line. On a
per-character terminal, you must clear the area where the modes
are set. On a magic cookie terminal, you must clear an area
containing the cookie. See the discussion above.
Flag whose presence means that the cursor cannot be positioned
right in front of a magic cookie, and that `se' is a command to
delete the next magic cookie following the cursor. See discussion
above.
String of commands to enter blinking mode.
String of commands to enter double-bright mode.
String of commands to enter half-bright mode.
String of commands to enter invisible mode.
String of commands to enter protected mode.
String of commands to enter reverse-video mode.
String of commands to turn off all appearance modes, including
standout mode and underline mode. On some terminals it also turns
off alternate character set mode; on others, it may not. This
capability must be present if any of `mb' ... `mr' is present.
String of commands to turn on alternate character set mode. This
mode assigns some or all graphic characters an alternate picture
on the screen. There is no standard as to what the alternate
pictures look like.
String of commands to turn off alternate character set mode.
String of commands to turn on an arbitrary combination of
appearance modes. It accepts 9 parameters, each of which controls
a particular kind of appearance mode. A parameter should be 1 to
turn its appearance mode on, or zero to turn that mode off. Most
terminals do not support the `sa' capability, even among those
that do have various appearance modes.
The nine parameters are, in order, STANDOUT, UNDERLINE, REVERSE,
BLINK, HALF-BRIGHT, DOUBLE-BRIGHT, BLANK, PROTECT, ALT CHAR SET.
File: termcap, Node: Underlining, Next: Cursor Visibility, Prev: Standout, Up: Capabilities
Underlining
===========
Underlining on most terminals is a kind of appearance mode, much like
standout mode. Therefore, it may be implemented using magic cookies or
as a flag in the terminal whose current state affects each character
that is output. *Note Standout::, for a full explanation.
The `ug' capability is a numeric capability whose presence indicates
that the terminal uses magic cookies for underlining. Its value is the
number of character positions that a magic cookie for underlining
occupies; it is used for underlining just as `sg' is used for standout.
Aside from the simplest applications, it is impossible to use
underlining correctly without paying attention to the value of `ug'.
String of commands to turn on underline mode or to output a magic
cookie to start underlining.
String of commands to turn off underline mode or to output a magic
cookie to stop underlining.
Width of magic cookie that represents a change of underline mode;
or missing, if the terminal does not use a magic cookie for this.
Flag whose presence means that it is safe to move the cursor while
the appearance modes are not in the normal state. Underlining is
an appearance mode. If this flag is absent, programs should
always turn off underlining before moving the cursor.
There are two other, older ways of doing underlining: there can be a
command to underline a single character, or the output of `_', the
ASCII underscore character, as an overstrike could cause a character to
be underlined. New programs need not bother to handle these
capabilities unless the author cares strongly about the obscure
terminals which support them. However, terminal descriptions should
provide these capabilities when appropriate.
String of commands to underline the character under the cursor, and
move the cursor right.
Flag whose presence means that the terminal can underline by
overstriking an underscore character (`_'); some terminals can do
this even though they do not support overstriking in general. An
implication of this flag is that when outputting new text to
overwrite old text, underscore characters must be treated
specially lest they underline the old text instead.

Cursor Visibility
=================
Some terminals have the ability to make the cursor invisible, or to
enhance it. Enhancing the cursor is often done by programs that plan
to use the cursor to indicate to the user a position of interest that
may be anywhere on the screen--for example, the Emacs editor enhances
the cursor on entry. Such programs should always restore the cursor to
normal on exit.
String of commands to enhance the cursor.
String of commands to make the cursor invisible.
String of commands to return the cursor to normal.
If you define either `vs' or `vi', you must also define `ve'.
File: termcap, Node: Bell, Next: Keypad, Prev: Cursor Visibility, Up: Capabilities
Here we describe commands to make the terminal ask for the user to
pay attention to it.
String of commands to cause the terminal to make an audible sound.
If this capability is absent, the terminal has no way to make a
suitable sound.
String of commands to cause the screen to flash to attract
attention ("visible bell"). If this capability is absent, the
terminal has no way to do such a thing.
File: termcap, Node: Keypad, Next: Meta Key, Prev: Bell, Up: Capabilities
Keypad and Function Keys
========================
Many terminals have arrow and function keys that transmit specific
character sequences to the computer. Since the precise sequences used
depend on the terminal, termcap defines capabilities used to say what
the sequences are. Unlike most termcap string-valued capabilities,
these are not strings of commands to be sent to the terminal, rather
strings that are received from the terminal.
Programs that expect to use keypad keys should check, initially, for
a `ks' capability and send it, to make the keypad actually transmit.
Such programs should also send the `ke' string when exiting.
String of commands to make the function keys transmit. If this
capability is not provided, but the others in this section are,
programs may assume that the function keys always transmit.
String of commands to make the function keys work locally. This
capability is provided only if `ks' is.
String of input characters sent by typing the left-arrow key. If
this capability is missing, you cannot expect the terminal to have
a left-arrow key that transmits anything to the computer.
String of input characters sent by typing the right-arrow key.
String of input characters sent by typing the up-arrow key.
String of input characters sent by typing the down-arrow key.
String of input characters sent by typing the "home-position" key.
`K1' ... `K5'
Strings of input characters sent by the five other keys in a 3-by-3
array that includes the arrow keys, if the keyboard has such a
3-by-3 array. Note that one of these keys may be the
"home-position" key, in which case one of these capabilities will
have the same value as the `kh' key.
String of input characters sent by function key 10 (or 0, if the
terminal has one labeled 0).
`k1' ... `k9'
Strings of input characters sent by function keys 1 through 9,
provided for those function keys that exist.
Number: the number of numbered function keys, if there are more
than 10.
`l0' ... `l9'
Strings which are the labels appearing on the keyboard on the keys
described by the capabilities `k0' ... `l9'. These capabilities
should be left undefined if the labels are `f0' or `f10' and `f1'
... `f9'.
String of input characters sent by the "home down" key, if there is
one.
String of input characters sent by the "backspace" key, if there is
one.
String of input characters sent by the "clear all tabs" key, if
there is one.
String of input characters sent by the "clear tab stop this column"
key, if there is one.
String of input characters sent by the "clear screen" key, if
there is one.
String of input characters sent by the "delete character" key, if
there is one.
String of input characters sent by the "delete line" key, if there
is one.
String of input characters sent by the "exit insert mode" key, if
there is one.
String of input characters sent by the "clear to end of line" key,
if there is one.
String of input characters sent by the "clear to end of screen"
key, if there is one.
String of input characters sent by the "insert character" or "enter
insert mode" key, if there is one.
String of input characters sent by the "insert line" key, if there
is one.
String of input characters sent by the "next page" key, if there is
one.
String of input characters sent by the "previous page" key, if
there is one.
String of input characters sent by the "scroll forward" key, if
there is one.
String of input characters sent by the "scroll reverse" key, if
there is one.
String of input characters sent by the "set tab stop in this
column" key, if there is one.
String listing the other function keys the terminal has. This is a
very obsolete way of describing the same information found in the
`kH' ... `kT' keys. The string contains a list of two-character
termcap capability names, separated by commas. The meaning is
that for each capability name listed, the terminal has a key which
sends the string which is the value of that capability. For
example, the value `:ko=cl,ll,sf,sr:' says that the terminal has
four function keys which mean "clear screen", "home down", "scroll
forward" and "scroll reverse".
File: termcap, Node: Meta Key, Next: Initialization, Prev: Keypad, Up: Capabilities
Meta Key
========
A Meta key is a key on the keyboard that modifies each character you
type by controlling the 0200 bit. This bit is on if and only if the
Meta key is held down when the character is typed. Characters typed
using the Meta key are called Meta characters. Emacs uses Meta
characters as editing commands.
Flag whose presence means that the terminal has a Meta key.
String of commands to enable the functioning of the Meta key.
String of commands to disable the functioning of the Meta key.
If the terminal has `km' but does not have `mm' and `mo', it means
that the Meta key always functions. If it has `mm' and `mo', it means
that the Meta key can be turned on or off. Send the `mm' string to
turn it on, and the `mo' string to turn it off. I do not know why one
would ever not want it to be on.
File: termcap, Node: Initialization, Next: Pad Specs, Prev: Meta Key, Up: Capabilities
Initialization
==============
String of commands to put the terminal into whatever special modes
are needed or appropriate for programs that move the cursor
nonsequentially around the screen. Programs that use termcap to do
full-screen display should output this string when they start up.
String of commands to undo what is done by the `ti' string.
Programs that output the `ti' string on entry should output this
string when they exit.
String of commands to initialize the terminal for each login
session.
String which is the name of a file containing the string of
commands to initialize the terminal for each session of use.
Normally `is' and `if' are not both used.
Two more strings of commands to initialize the terminal for each
login session. The `i1' string (if defined) is output before `is'
or `if', and the `i3' string (if defined) is output after.
The reason for having three separate initialization strings is to
make it easier to define a group of related terminal types with
slightly different initializations. Define two or three of the
strings in the basic type; then the other types can override one
or two of the strings.
String of commands to reset the terminal from any strange mode it
may be in. Normally this includes the `is' string (or other
commands with the same effects) and more. What would go in the
`rs' string but not in the `is' string are annoying or slow
commands to bring the terminal back from strange modes that nobody
would normally use.
Numeric value, the initial spacing between hardware tab stop
columns when the terminal is powered up. Programs to initialize
the terminal can use this to decide whether there is a need to set
the tab stops. If the initial width is 8, well and good; if it is
not 8, then the tab stops should be set; if they cannot be set,
the kernel is told to convert tabs to spaces, and other programs
will observe this and do likewise.
String of commands to clear all tab stops.
String of commands to set tab stop at current cursor column on all
lines.
File: termcap, Node: Pad Specs, Next: Status Line, Prev: Initialization, Up: Capabilities
Padding Capabilities
====================
There are two terminal capabilities that exist just to explain the
proper way to obey the padding specifications in all the command string
capabilities. One, `pc', must be obeyed by all termcap-using programs.
Numeric value, the lowest baud rate at which padding is actually
needed. Programs may check this and refrain from doing any
padding at lower speeds.
String of commands for padding. The first character of this
string is to be used as the pad character, instead of using null
characters for padding. If `pc' is not provided, use null
characters. Every program that uses termcap must look up this
capability and use it to set the variable `PC' that is used by
`tputs'. *Note Padding::.
Some termcap capabilities exist just to specify the amount of
padding that the kernel should give to cursor motion commands used in
ordinary sequential output.
Numeric value, the number of msec of padding needed for the
carriage-return character.
Numeric value, the number of msec of padding needed for the newline
(linefeed) character.
Numeric value, the number of msec of padding needed for the
backspace character.
Numeric value, the number of msec of padding needed for the
formfeed character.
Numeric value, the number of msec of padding needed for the tab
character.
In some systems, the kernel uses the above capabilities; in other
systems, the kernel uses the paddings specified in the string
capabilities `cr', `sf', `le', `ff' and `ta'. Descriptions of
terminals which require such padding should contain the `dC' ... `dT'
capabilities and also specify the appropriate padding in the
corresponding string capabilities. Since no modern terminals require
padding for ordinary sequential output, you probably won't need to do
either of these things.
File: termcap, Node: Status Line, Next: Half-Line, Prev: Pad Specs, Up: Capabilities
Status Line
===========
A "status line" is a line on the terminal that is not used for
ordinary display output but instead used for a special message. The
intended use is for a continuously updated description of what the
user's program is doing, and that is where the name "status line" comes
from, but in fact it could be used for anything. The distinguishing
characteristic of a status line is that ordinary output to the terminal
does not affect it; it changes only if the special status line commands
of this section are used.
Flag whose presence means that the terminal has a status line. If
a terminal description specifies that there is a status line, it
must provide the `ts' and `fs' capabilities.
String of commands to move the terminal cursor into the status
line. Usually these commands must specifically record the old
cursor position for the sake of the `fs' string.
String of commands to move the cursor back from the status line to
its previous position (outside the status line).
Flag whose presence means that other display commands work while
writing the status line. In other words, one can clear parts of
it, insert or delete characters, move the cursor within it using
`ch' if there is a `ch' capability, enter and leave standout mode,
and so on.
String of commands to disable the display of the status line. This
may be absent, if there is no way to disable the status line
display.
Numeric value, the width of the status line. If this capability is
absent in a terminal that has a status line, it means the status
line is the same width as the other lines.
Note that the value of `ws' is sometimes as small as 8.
File: termcap, Node: Half-Line, Next: Printer, Prev: Status Line, Up: Capabilities
Half-Line Motion
================
Some terminals have commands for moving the cursor vertically by
half-lines, useful for outputting subscripts and superscripts. Mostly
it is hardcopy terminals that have such features.
String of commands to move the cursor up half a line. If the
terminal is a display, it is your responsibility to avoid moving
up past the top line; however, most likely the terminal that
supports this is a hardcopy terminal and there is nothing to be
concerned about.
String of commands to move the cursor down half a line. If the
terminal is a display, it is your responsibility to avoid moving
down past the bottom line, etc.
File: termcap, Node: Printer, Prev: Half-Line, Up: Capabilities
Controlling Printers Attached to Terminals
==========================================
Some terminals have attached hardcopy printer ports. They may be
able to copy the screen contents to the printer; they may also be able
to redirect output to the printer. Termcap does not have anything to
tell the program whether the redirected output appears also on the
screen; it does on some terminals but not all.
String of commands to cause the contents of the screen to be
printed. If it is absent, the screen contents cannot be printed.
String of commands to redirect further output to the printer.
String of commands to terminate redirection of output to the
printer. This capability must be present in the description if
`po' is.
String of commands to redirect output to the printer for next N
characters of output, regardless of what they are. Redirection
will end automatically after N characters of further output. Until
then, nothing that is output can end redirection, not even the
`pf' string if there is one. The number N should not be more than
255.
One use of this capability is to send non-text byte sequences
(such as bit-maps) to the printer.
Most terminals with printers do not support all of `ps', `po' and
`pO'; any one or two of them may be supported. To make a program that
can send output to all kinds of printers, it is necessary to check for
all three of these capabilities, choose the most convenient of the ones
that are provided, and use it in its own appropriate fashion.
