Advice needed - How to resolve serial port conflicts Windows XP
I have a brand new Dell Optiplex system I am setting up as a POS. This requires 3 serial ports so I added a 2 port serial card for a grand total of three serial ports. Although Windows XP reports no conflicts between the ports, the system sort of hangs up whenever I plug a device into a port on the serial card I added. Can somone point me in the direction of resolving this? Im lost since XP shows that there arent any conflicts when obviously there are. IRQs are all different for each of the three ports.
