More than 2 modems can cause grief real fast. PC clones normally have
only two interrupt codes for serial ports. You can't just add new ones
willy-nilly, they're very much built into the hardware and the
drivers.

I suggest that for this many modems, you definitely need some sort of
serial expander. Alternatively, there are several types of network
ready multiple modem servers which might save you a lot of work and
grief and be overall more reliable: you might then be able to use the
Linux box to handle the fax service. I believe some people have done
this on this group....
