[comp.dcom.modems] Multi-Tech EC2400 problems

Here's a problem that has the Multi-Tech support people stymied. I though
throw it out for suggestions. Any and all would be appreciated.
Hardware: Zenith 286, Multi-Tech EC2400 internal modem.
Software: Procomm Plus
Configuration: Com 1 ISN network, Com 2 Microsoft serial mouse, Com 4 modem.

The Problem: I pulled the modem card out of a Zenith 386 where it worked fine.
When I installed it into the 286 all would appear normal i.e., it dialed,
found a carrier, but then no response. It was installed in com 3. I called
Multi-Tech and they said the serial mouse (386 had a bus mouse) was conflicting
with the modem (something about IRQ conflicts, but I'm no techie) Anyway
we played with the dip switches. And Com 4 seemed to work. And it does,
sometimes. Sometimes it answers the carrier, sometimes it doesn't. Sometimes
I lose my mouse and have to reboot after a modem session. Sometimes it won't
respond to a carrier and I still lose my mouse.

So there it is as best as I can explain it. I've been on the phone to Multi-
Tech support several times. I get different answers from different people.
Nothing has worked.  Any suggestions to this irritating problem would be
most appreciated.

This may sound funny but I would try using the unit from com1 or com2. Support
for Com3 and Com4 can be flaky. Are you using windows by any chance? If yes
that could very well be your problem.
