16.5 Special Terminal Capabilities

The following table describes all terminal capabilities that are recognized by screen and are not in the termcap manual (see Termcap). You can place these capabilities in your termcap entries (in /etc/termcap) or use them with the commands termcap, terminfo and termcapinfo in your screenrc files. It is often not possible to place these capabilities in the terminfo database.

‘LP’

(bool)
Terminal has VT100 style margins (‘magic margins’). Note that this capability is obsolete — screen now uses the standard ‘xn’ instead.

‘Z0’

(str)
Change width to 132 columns.

‘Z1’

(str)
Change width to 80 columns.

‘WS’

(str)
Resize display. This capability has the desired width and height as arguments. SunView(tm) example: ‘\E[8;%d;%dt’.

‘NF’

(bool)
Terminal doesn’t need flow control. Send ^S and ^Q direct to the application. Same as flow off. The opposite of this capability is ‘nx’.

‘G0’

(bool)
Terminal can deal with ISO 2022 font selection sequences.

‘S0’

(str)
Switch charset ‘G0’ to the specified charset. Default is ‘\E(%.’.

‘E0’

(str)
Switch charset ‘G0’ back to standard charset. Default is ‘\E(B’.

‘C0’

(str)
Use the string as a conversion table for font 0. See the ‘ac’ capability for more details.

‘CS’

(str)
Switch cursor-keys to application mode.

‘CE’

(str)
Switch cursor-keys to cursor mode.

‘AN’

(bool)
Enable autonuke for displays of this terminal type. (see Autonuke).

‘OL’

(num)
Set the output buffer limit. See the ‘obuflimit’ command (see Obuflimit) for more details.

‘KJ’

(str)
Set the encoding of the terminal. See the ‘encoding’ command (see Character Processing) for valid encodings.

‘AF’

(str)
Change character foreground color in an ANSI conform way. This capability will almost always be set to ‘\E[3%dm’ (‘\E[3%p1%dm’ on terminfo machines).

‘AB’

(str)
Same as ‘AF’, but change background color.

‘AX’

(bool)
Does understand ANSI set default fg/bg color (‘\E[39m / \E[49m’).

‘XC’

(str)
Describe a translation of characters to strings depending on the current font. (see Character Translation).

‘XT’

(bool)
Terminal understands special xterm sequences (OSC, mouse tracking).

‘C8’

(bool)
Terminal needs bold to display high-intensity colors (e.g. Eterm).

‘TF’

(bool)
Add missing capabilities to the termcap/info entry. (Set by default).
