Docs wanted: Motorola Universal Data Systems 212A/D

I came across this today and rescued it:



However, documentation seems to be very hard to find. I have found some manuals for earlier modems from the same company, but not anything for this modem. By chance there was a paper note inside of the cover that gave me the magic sequence to get into a menu system, but I'd like to get a full set of docs. (The sequence was "EN".)

Ever use or see one of these? If so, tell me your story.

Golly, back in the day, the UDS modems were just as common as the Milgo, Vadic and Bell modems. It's surprising that docs haven't been preserved on these. (I don't have any)

Yep. Bitsavers is empty too, which was a surprise.

I'm looking at a few of these modems for my PDP-11/44 setup... Did you end-up finding any documentation?
