* CSI Ps c Send Device Attributes (Primary DA).

* -> CSI ? 1 ; 2 c (``VT100 with Advanced Video Option'')

* The VT100-style response parameters do not mean anything by
* themselves. VT220 parameters do, telling the host what fea-
* tures the terminal supports:
* Ps = 1 -> 132-columns.
* Ps = 2 -> Printer.
* Ps = 6 -> Selective erase.
* Ps = 8 -> User-defined keys.
* Ps = 9 -> National replacement character sets.
* Ps = 1 5 -> Technical characters.
* Ps = 2 2 -> ANSI color, e.g., VT525.
* Ps = 2 9 -> ANSI text locator (i.e., DEC Locator mode).
* CSI > Ps c
* Send Device Attributes (Secondary DA).
* Ps = 0 or omitted -> request the terminal's identification
* code. The response depends on the decTerminalID resource set-
* ting. It should apply only to VT220 and up, but xterm extends
* this to VT100.
* -> CSI > Pp ; Pv ; Pc c
* where Pp denotes the terminal type
* Pp = 0 -> ``VT100''.
* Pp = 1 -> ``VT220''.
* and Pv is the firmware version (for xterm, this was originally
* the XFree86 patch number, starting with 95). In a DEC termi-
* nal, Pc indicates the ROM cartridge registration number and is
* always zero.
* More information:
* xterm/charproc.c - line 2012, for more information.
* vim responds with ^[[?0c or ^[[?1c after the terminal's response (?)
