Modems that still have a 16550 based uart interface to them, but just happen to sit on the PCI bus. I'm not at all planning on writing support for winmodems, just making sio.c understand UARTs on the PCI bus. There *are* PCI modems out there that aren't winmodems, they're just hard to find. 3Com makes one, as well as a few other companies.
