Well, I have an Intel Connection Co-Processor in my machine at work. The way
you tell the CCP to answer with the modem and not the fax is to set the
"ATS0=1" register, for answering on the first ring. This takes care of it.

The Intel CCP has an 80188 processor on board. It shares the bus and does all
of its "faxing" in the background. This includes storing it on disk as it
comes in. The problem with most fax machines makes your computer become a Fax
ONLY. The CCP allows you to go about your business and receives them at will.

Yes. Again, the Intel CCP allows you to send out a request for a certain
document to the remote fax.

I only have experience with the Intel CCP because it's part of my job.
