I'm trying to use the serial port header on an Intel DQ965GF mainboard with XP pro. Windows detects and installs the associated COM port but it doesn't work. I've tried printing through it and installing a modem on it. It WILL NOT detect anything hooked to that port. I have 5 machines with the same motherboard and it doesn't work on any of them.
I have flashed to the latest BIOS and also installed the latest chipset drivers. Thoughts?
