I installed a US robotics 56k pci controlle-based faxmodem in a dell optiplex gx110. The com port was setup as 5 (plug and play). The software that I have can only use com ports 1,2,3, & 4.When I try to manually change the modem to one of the above ports, I get an in use error message. There is no where in the bios for me to disable com 2 as some tech papers sugested. The vendor will not upgrade software to recognize com 5, so that’s out of the question. Thanks for any help.
