yep, get a serial modem, one that is external to the pc itself.You will need a serial modem cable to go with it
Ive got some generic one I bought from pcliquidators.com that works fine

what your looking for is a HARD modem, one that has a chipset that has all the functions built in instead of a soft modem which requires software emulation for drivers, external modems have no choice but to be hard modems usually-->tough to do software emulation over a serial line
