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.
