OK silly question. How do I add a com port in XP ? It's been a long time since I've had to do this and XP is totallu different.

Thanks in advance.

ah ah ah. Need it for my card reader. Changing over all machines on network to XP (trying). There is only one com port installed and I need the second one also.
