I am not familiar with this modem, however, my basic assumption is that they
should support a standard, and common in practice, configuration of multiple
modems on a single cpu.  If so, I think the fault lies in IRQ sharing, and I
don't trust WIN XP.  I would try setting IRQ 3 and 4 to legacy support only
in the bios, disable all comm ports if any exist, make sure the modems are
set to ports 1 and 2, 2 and 3, 3 and 4, or 1 and 4 which are the only valid
pairings that will assign irq 3 to one modem and irq 4 to the other.

If the problem persists, I would guess one of the probable causes is a less
than perfect implementation of the original driver into Win XP, which would
be unresolvable by yourself.  This would discourage me from putting more
time in searching for a solution.

Here I am again with another hardware issue. I got a pair of Intel
hardware PCI modems - good price on e-bay ($9.95). Installation of one
modem went well; there was included software to support XP; modem runs
great. However, I wanted to use two modems with two phone lines in
mulitlink to increase my throughput. I had been doing this with some
older modems I had. Installed the second Intel modem and found that the
second modem did not work. Turns out that the modem is not bad, but when
two of these are installed in the same computer, problems happen. When I
tried to delete the non-working modem form the device manager display,
XP Pro crashed! This is perfectly repeatable on different system running
XP Pro.

Sinopsys: one modem runs fine. Two modems - big problems. Has anyone
else run into such problems with two PCI modems? Note that these are
hardware modems - not Winmodems. I would still like to know why it did not
work
with the two PCI devices installed.
