HAL Communications are still around AFAIK and the ham world is usually pretty good about
documentation etc.; might be worth sending them an inquiry:
http://www.halcomm.com/
Maybe even try to get in touch with Bill Henry:

I'm not sure about that.. I've been trying to find any documentation I can online
about it to understand more about how it works. I got it for $40 in non-working condition
-- turned out it does work. But detailed info seems to be sparse.

Just posting here in case anyone not on other forums I'm on sees this
and knows something about these.
I picked up a HAL DS-3100 ASR terminal. My understanding is these are
RTTY
devices intended for teletype/radio use. It is ASCII
compatible and
in
fact
I can select ASCII and baud rates from a menu. It has
a 25 pin male
'MODEM'
port on the back. I can't find it now but
somewhere I read it
complied
with
an RS-232 standard. I tried hooking it up to my PC
with a null modem
cable,
but couldn't get either to produce anything on
their screens.
Anyway, just a shot in the dark in case any of you remember these things.
I'm not really into HAM stuff, but it's a cool little terminal and I
was hoping it could be used/adapted to other tasks.

You have rules out that it is not a current loop terminal?
