I have this Dell Optiplex240 that is not reading the periferals hooked up to the COMM port. When I looked in the command prompt at the settings for the ports they were set the same and that dosn't look right to me because I thought only one is supposed to be "turned on" to work. I have spent the last week reading anything I can on Serial Ports and I have gone to the Dell site to find out what I can about that version of BIOS and how to change the settings but there is nothing out there. The BIOS version is A01 and the Service Tag is BRGY011. If someone can just point me in the right direction of where to look or what to try I would be much abliged.
