Just put together a new system, Abit KT7A with 1.33GHz T-Bird, but now am having trouble with U.S. Robotics 56k modem. When I first installed it, it worked fine. I began installing software and updating all of my programs. For some reason it stopped working and it keeps telling me that the port it is trying to use is already in use. I have tried changing the irq and the com port it is trying to use to no avail. I have also made sure that those ports are enabled in the bios which they are. I can't figure out why it thinks that the port is in use, any help would be appreciated. Thanks.
