Can I use WinDriver to define additional serial/parallel ports, using a PLX card?

Yes. You can plug-in the serial/parallel port or modem ISA device to a PLX card, then use WinDriver to write a driver application that loads before Windows' standard serial/parallel port driver, detects your PCI hardware and its resources, and writes the resources back to the port's Registry. Then, when the port driver loads, it will install itself also on your serial/parallel port.

A working sample for a serial port driver for Windows NT 4.0, based on the PLX 9050 hardware, can be found in the WinDriver/plx/9050/serial/ directory.
