[sci.electronics] ComData T212A modemfromhell

Does anyone have experience with a ComData T212A 300/1200 baud
modem?  (The thing was built back in 1979.)  I'm trying to get
it working for a friend who wants a home terminal without the
need for speed.

There is a row of lights on the front, reading:

MB  TR  MR  SD  RD  HS  MC  ?M

(? = it's been rubbed off)

and a row of switches that reads:

AL  ST  RDL  DL  HS

The back has a male DB25 for the phone line (!) and a DB25 for
the RS232.  The only documentation I have is a sticker on the
bottom explaining (for the designers only, it seems) the settings
of an internal dip switch that I don't want to mess with.

If there are any clues on how to use the thing, please respond
via e-mail.  Also, if you have one in a closet, let me know and
I'll forward any interesting replies to you.
