The problem is that most PCI modems are controllerless "WinModems". A hardware modem has its own CPU that responds to AT commands, dials telephone numbers, and negotiates speed, error correction and compression protocols with other modems. A "WinModem" relies on the PC to do all the work. For this it needs driver software that is only available for Windows 9x (or Linux for some modems, see www.linmodems.org).
