I ran across this modem (circa 1982) and saved it, but I have no idea on
how to control it. Bitsavers doesn't seem to have a manual for it.
It's a big, blue plastic box and it looks wonderful. There is an array of
8 lights and 6 buttons; the HS button enables 1200 bps operation, otherwise
it is 300 bps. It echoes characters and responds correctly to
DataTerminalReady not being asserted, so I think that if I can find the
command set it might be functional.
It's a little more primitive than my original Hayes 1200 that I first got
in 1984. (I'm not expecting a standard command set.) A picture of it can
be found here:

Brent - thanks! I had found the arcelect site and read the docs on a few
related modems; that gave me some insight. But a lot of what they have is
more primitive that this one, so much of the manuals do not apply.
I opened the case looking for clues and taped to the underside of the lid
was a handwritten note that said "To awaken the UDS 212A/D mode send to UT
capital EN or H Help menu." It was a little cryptic but sending "EN" did
launch me into a menu system that would let me dial or set pre-set phone
numbers for dialing.
At the moment it auto answers and tries to dial, but it won't complete a
connection. My VOIP line might be to blame for that. I'm happy because I
got really lucky with the handwritten note ...

You might try the v.25bis command set:
