Is anyone out there old enough, that might remember the old Dell Optiplex GX280, and give me some advice on how to troubleshoot the 9 pin serial port?
I have a device that works from the serial port and works when I plug it into a borrowed Dell Dimension 2350 PC but I can't get it to work with that GX280 PC. Device Manager shows only COM1 and LPT1 and both are showing they are working properly?
huwyngr thank you for that link and reply. There is a lot of information in there that I hope will help me solve that serial port problem. I really don't know if it has ever worked because I haven't needed it. Most everything I'm currently using are the USB drivers. The old nine pin serial port is almost going the way of the old as the 5 1/4 inch drives. I'll read through that link and get back to you.
huwyngr - Your link gave me the clue that helped me solve my serial problem. I again thank you for the posts. After reading your link, I was given a hint that led me to discover that I already had some PC to PC communictation using the serial port. Even though the PC's were not connected, the port was showing it was still in use. After I deleted that communication setup, the serial port started working again. Thanks again for you clue..

Wow! You made my day! <g>
I'm glad you resolved the problem because USB/Serial converters are notoriously unreliable and should be avoided like the plague. Much better on a desktop anyway to put a PCI type plug in serial board and get the real thing, and may be even cheaper than a converter.
