I don't have such a beast in my machine, but I remember someone posting
how to get a PCI modem (controller-based, not winmodem) working under
Linux.
However, from what I remember, you want to do an 'lspci -v', or 'cat
/proc/pci' if you don't have a 2.0 kernel, and look for an unknown device
or a 'serial controller' or something similar. You should see a value for
I/O ports. If your PCI serial card uses a UART instead of memory mapping
you should see an IO port for each of the serial ports, and you would want
to give those port addresses and the card's IRQ to serserial.
Again, I'm going completely from memory here, and I know I'm missing some
information you'll need to make it actually work, but hopefully I've
pointed you in the right direction.
I know (unless I'm really lucky) you might hose your system if you do
setserial without double-checking everything. SO MAKE SURE YOU FIND OUT
WHAT YOU'RE DOING first.
Hope you can get it working.
