The modems in both cases are similar: Multitech external > and Multitech internal. Both have MNP, but only the caller is in auto- 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. -- ========================================================================== Disclaimer: are you kidding?
