The ZOOM 2400 Baud modems are Decent modems.
At least 3 models of the 2400 exist.
A half card PC internal which supports COM1-4
An external model which is wall mountable.
And a full size internal version that has far too many options to 
describe here.
Some of the nice features of the big-board model are automatic DTMF
tone recognition, a built in bbs, voice recording and playback
Real-time clock built in.

Ive used the half-card version on my DOS BBS with excellent results.
Approx 34% of my callers use 2400 Baud.

I recently tried it on the XENIX box and it worked well for dial-out.
Dial in worked ok too when I used the non-modem tty.
(no auto logoff an disconnect).
Almost certainly I didn't have it configured properly because when I 
used the modem port  (TTY1A rather than TTY1a), the modem would connect
OK but the system would send a message to the console saying...
"garbage or loose cable on port9, shutting port down" or similar
Then XENIX would disconnect me.

Anybody know why this happens?

Oh other nice things about ZOOM modems is that they use the
Fast UART chip (not the flakey 8250A which misses interrupts)
They all have adaptive equalization.
