I'm pretty sure you have an accident here, but only because both of your
modems are by the same manufacturer. I have been using the MT224EH as the
only working modem on this 3B1 for about a year now, and had a devil of a
time getting it set up properly. The modem serial port is strapped for NO-AUTO-
BAUD, but the modem phone port is set to auto-baud. This forces the modem to
buffer the data, and conduct speed changes. I also had to disable the modems
own handshaking so that only the remote devices perform the xon/xoff (the
modems do pass it through, but take no action). The cable had to be correct,
the cpu port had to ignore dtr/rts/cts, the modems had to do the speed changes,
and they had to ignore stop/start, before I finally got everything to work
with lot's of different remotes.
