The following table describes all terminal capabilities that are recognized by screen and are not in the termcap(5) manual. 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 as VT100 style margins (“magic margins”). Note that this capability is obsolete because screen uses the standard xn instead.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™ 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 back to normal mode. |
| AN | (bool) | Turn on autonuke. See the autonuke command for more details. |
| OL | (num) | Set the output buffer limit. See the obuflimit command for more details. |
| KJ | (str) | Set the encoding of the terminal. See the encoding command for valid encodings. |
| AF | (str) | Change character foreground color in an ANSI conformant 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. More details follow in the next section. |
| 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). |
