Serial Port Not Working.

For some reason my serial port does not want to work. I have tried 3
different computers. A Windows XP, Windows 2000 and a Linux box
running Ubuntu. Both Windows machines I tried HyperTerminal and
Putty. For Linux I used minicom. All of these program do the same
thing, they show a blinking cursor. The S-Video out works and so does
the audio out. I do not know about the DVI-D out because I don't have
the hook ups for that. I just want to see if it is a PEBKAC problem
or it really is a bad serial port. The IDC10-DB9M adapter that I am
using is from http://www.pccables.com/07120.htm The serial cable that
I am using is from Radio Shack. A standard RS232 DB9F to DB9F with a
pin out of 1-1, 2-2, 3-3, 4-4, 5-5, 6-6, 7-7, 8-8, 9-9. Here is a
picture of the IDC10 connected to the Beagle Board to make sure that I
am plugging it in the right way, http://www.flickr.com/photos/29554476@N04/2761879892/
The red cable I assume is pin 1, but hey what do I know. If anyone
has any suggestion please let me know

Thanks for the help.

That's your problem. You need a null modem cable. This
has pairs 2-3, 4-6, and 7-8 crossed.

That sounds like a straight through cable, you need a null modem cable where
pins 2 and 3 are crossed over.

Have a look at the diagram at

for
the pinout "Simple null modem without handshaking"

I had the same problem. I had a DB9F-DB9F cable which i though was
crossed but that was not in reallity...
If you want to do the change quickly and easily, just switch the pin 2
& 3 of the DB9M of the ICD10-DB9M adapter with a soldier iron.

Thanks for the help. Switching pins worked!! I figured it was some
stupid thing on my part and it was.
