I did find an old Computerworld ad from 1989 which matched. Informer
213 - emulating a 3274 control unit with an attached 3178 mod 2 terminal.
Someone with IBM knowledge might share what that means and how the
terminal can be used.
Reading the add it looks like you need a dial-up SDLC (that?s synchronous
data)
link into a mainframe with a telecoms controller running VTAM, l which I
guess is as rare as hens teeth these days.
When you get to the set up menu's can you
check if it can run bi-sync as that
might be hackable, providing a suitable
synchronous modem can be found.
Some time around 1992, give or take, there were piles of Informer 207s for
sale cheap at the Dayton Hamfest. We were doing Bisync and SNA products at
the time, so we bought a couple. We were able to fiddle our environment
enough to get one of them to connect - our flagship product was an SNA PU
type 2, much like a 3274 terminal controller, but with interactive sessions via
VT100 + software 3270 emulation instead of a real IBM 3270. My memory is
that you could dial up your
37x5 (via sync modem, as Dave mentioned) from one Informer 207, then attach
several "child" Informer 207s to the first, as if you had a real 3274 +
multiple
3270s. I have to think the later Informer terminals had the same functionality
(unless it was later determined that it was "better" (and/or cheaper) to do
one-
modem-one-user instead of supporting a remote office and multiple sessions
off of one connection.
Essentially, what we had to do with out Informer 207 was to provision our
environment pretty much the same as adding a new 3274 and get the settings
to match on both sides of the phone line. I think it took a few hours of fiddling
to get both sides happy.
The 207 was SNA-only. It did not support HASP or 3780, the predominant bisync
protocols (we supported those on other products, and they are _far_ simpler
than anything SNA).
Sorry I don't have any data on the 213. It sounds like a device we would have
liked to have had 20+ years ago.

Looking at the documents on the web it looks like the AE is a straight forward VT100
terminal, the PT was the 3270 version.
If it is an AE it should work with any Unix/Linux/PDP/VAX etc. etc. out of the box.
