Both com ports claimed my USR Sportster modem wasn't functioning properly. I knew it worked perfectly. I tested both ports with feedback plugs and MDR, the shareware modem doctor. Both UARTS failed analog feedback. In other words, both ports were useless. I am using an old controller card for my com ports now. I have seen a report that you have to use the cables that came with the motherboard for the ports to work. I did use them. In fact they were in use when I did my testing. MDR tests work fine on the controller board I have in there.
