Add some documentetion to tsetmode |
|
|
|
The names of the terminal modes supported by vt102 are (taken from the VT220 |
|
programmer reference manual): |
|
|
|
Table 4-7 ANSI-Standardized Modes |
|
Name Mnemonic Parameter (Ps) |
|
Error (ignored) - 0 (3/0) |
|
Keyboard action KAM 2 (3/2) |
|
Insert/replace IRM 4 (3/4) |
|
Send/receive SRM 12 (3/1 3/2) |
|
Line feed/new line LNM 20 (3/2 3/0) |
|
|
|
Table 4-8 ANSI-Compatible DEC Private Modes |
|
Name Mnemonic Parameter (Ps) |
|
Error (ignored) - 0 (3/0) |
|
Cursor key DECCKM 1 (3/1) |
|
ANSI/VT52 DECANM 2 (3/2) |
|
Column DECCOLM 3 (3/3) |
|
Scroll DECSCLM 4 (3/4) |
|
Screen DECSCNM 5 (3/5) |
|
Origin DECOM 6 (3/6) |
|
Auto wrap DECAWM 7 (3/7) |
|
Auto repeat DECARM 8 (3/8) |
|
Printer form feed DECPFF 18 (3/1 3/8) |
|
Printer extent DECPEX 19 (3/1 3/9) |
|
Text cursor enable DECTCEM 25 (3/2 3/5) |
|
National replacement character sets DECNRCM 42 (3/4 3/2) |
|
|
|
This patch adds a comment for each one of these sequences. |
