I misread "modem PCI board" as "modern PCI board" in your original post. The
correct response is much shorter:

You should use the existing serial devices.

No. You should copy how the existing devices (eg. serial ports) work.
You don't need parallel operation. Modems are low-bandwith devices, so you're
not going to get any performance benefit from using multiple threads.
