I'm looking for ways to automatically identify a fairly wide variety of
terminals...a technique which if it failed could then fall into a routine
that asked the user what was being used.

So, I'm collecting ideas on how to identify various terminals by sending
various sorts of escape or control sequences.

Here is my preliminary list of terminal responses to the ANSI "Device
Attributes" code which is:

	ESC [ P 0 c

or, because the ANSI spec allows the zero to be dropped:

	ESC [ P c

Except as noted, most of these terminals also respond in the same way to the
older DEC "identify" command sequence: 

	ESC Z

Note: "ESC" means the escape character, spaces appear below for clarity
only, an actual space would be coded "SP".

response string				terminal

ESC / Z					vt52 (response to ESC Z only)
ESC [ = 1 ; 1 c				Concept (one graphics page)
ESC [ = 1 ; 2 c				Concept (two graphics pages)
ESC [ ? 1 0 c				la100 or la120
ESC [ ? 1 2 ; 7 0 ; 102 c		DEC PRO 350 in vt125 mode
ESC [ ? 1 3 c				lqp02
ESC [ ? 1 ; 0 c				vt100, no options
ESC [ ? 1 ; 1 c				vt100, STP
ESC [ ? 1 ; 1 1 c			vt100, AC option?
ESC [ ? 1 ; 2 c				vt100, AVO (usual vt100)
ESC [ ? 1 ; 3 c				vt100, AVO & STP
ESC [ ? 1 ; 4 c				vt100, GPO
ESC [ ? 1 ; 5 c				vt100, GPO & STP
ESC [ ? 1 ; 6 c				vt100, GPO & AVO
ESC [ ? 1 ; 7 c				vt100, GPO, STP & AVO
ESC [ ? 2 6 c				ln03
ESC [ ? 6 2 ; 1 ; 2 ; 6 ; 7 ; 8 c	vt220
ESC [ ? 6 c				vt102
ESC [ ? 7 c				vt131
ESC [ ? 8 c				TeleVideo 970

(some of those are from Mike Cooper's qterm program, others I've come
across myself.)

The TeleVideo 910 thru 950 models don't understand the ANSI DA or ESC Z
inquiry, but it doesn't seem to affect them to send it.  One way to check
for those terminals as a group would be to send "ESC ?" which should return
two characters indicating cursor row/column...whie being a benign string
(should be ignored) by most ANSI-type terminals.
