Bad.

Try to get a logfile from Exchange.  If that one works in class 2 mode,
I'm very much interested to see what they do differently.  If they run the
modem in class 1 mode (what I suspect), don't bother - in class 1 mode,
the modem firmware can be very dumb, because the host CPU does all the
work.

incoming fax call recognized.

So far, everything fine.

But the sender and your modem can't agree upon actually starting a page
transfer.

Try different sending fax machines, and different modems on your end to
pin down the problem.  I'd say that this is a firmware problem that only
MultiTech can do something about.

Ah, there *is* the log file. Great. Let's see...

Hmmm, that's just the basic modem initialization, no *FAX*
commands/responses.  So this is pretty useless :-(
