        Tim,
        No DIN or weird 3 pin doodad, in fact it looks like I could go
out to RS and buy any 'ol wall transformer for it. The connector is
the same used in US Robotics modems, most Walkmans, portable CD
Players, etc. Basically a hollow cylinder on the jack with conductors
on the inside and outside of the cylinder. This plugs into the back
of the modem, which has a recepticle for the plug containing a small
pin in the center. I'm sure you know what I mean, but I don't know
the term for this kind of plug.

        Anyway, it looks deceptivly simple, but I don't want to go out
and buy the wrong transformer only to discover that I've blown the
modem. Does it take 12V, 9V, 3V, AC or DC (probably DC)? Oh well. I
also wrote Telebit, which was recently bought out, but I'm not
expecting an answer from them any time soon.

Thanks for the quick responce!
