I have just gotten an original box, foam pads inside that has a manual
and modem inside, probably unused. It says it's a Motorola UDS 201 BC,
made for Motorola by Universal Data Systems of Huntsville AL. The
manual says it's copyright 1986. Has the cable to connect to the regular
RJ11 lines (telco) and and RJ45 connector on back to hook in multline
phones or regular lines dependant upon the cable used. It also has a 25
pin d-sub on back but it's a female, marked DTE and the manual says its
an RS-232C connection. Pretty much like any external modem except for
the front switch positions. It's a rotary switch with the following
positions:
RDLIST
RDL
LDL
AL
DATA
TLK
TTP
RTP
ST
and it has 8 leds that are marked
MR/RI
TR
RS
CS
CD
RD
TD
TM
My guess is that it will do a multitude of things more than a stock dial
up modem. Many of you that have been into his stuff when it was new
probably know all about it.
Anyone willing to make a trade of some standard PC oriented stuff? PS/2
items? make me an offer if you want this as I don't think it's worth
much in $$ but a lot to someone that uses this type of equipment or for
their collection. A little high brow for me.

After spending seven years with Motorola, I consider myself
well qualified to comment on this beastie.
What you have there is one of the early 4-wire leased-line
modems. It requires another Motorola 201 or compatible on the opposite
end to talk to, and is not capable of handling dial-up connections
because it has no autodialer in it. It was designed pretty much
exclusively for dedicated private lines.
It tops out at 2400bps, speed-wise, and was designed to handle
synchronous transmission only. There's a weak possibility that a
commercial datacomm company might still be interested in it, but I've
seen people having trouble -giving- those things away at swap meets.

Apart from the "gee, that really was slow" potential for demonstration,
recreating the past, is there *any* use for old modems?

Sure: poor-man's Network Interface Card. I wrote a Ethernet IPX/SPX
translation program for a Commodore 64 and hooked the thing up to my
network (with a hardware converter between the modem and the hub of
course) at home. No real purpose to it for me, but it was a fun
project. Granted, the connection is slow as balls, but there it is
anyway!

Your question could be posed to most of us , substituting "old computer" for
"old modems" by anyone who's bought into the merchandising game perpetuated
by the computer corporations.

Luddite ? No, but I remember cars with 500 HP that you had to have otherwise
you'd be left standing at the stop sign. (And not get girrls)
