serial ports not working...

Hi again,
Uh, Simran, if I read your comment correctly then maybe the loopback test you described would not completely prove that the hardware was ok, because you said you only connected pins 2 and 3, and turned off the flow control. So what if somehow it was just the flow control pins that were at fault? I'm not sure if it's possible for that to happen, or for that matter for some virus etc to grab just one pin of a port- it sounds somehow unlikely, but the whole situation sounds kinda weird anyway The loopback circuit shown on the page Eric linked would be more complete.

Hi Tomble!

I read his last post a little differently--I think Simran was saying that the pin 2-to-3 thing would show (at least minimally) that the com port was working--and that they'd tried this and couldn't get any echo off it. If you read it right and I read it wrong, then I'm totally with you on this. I can't think of any reason for a virus to just grab the flow control pins either.

Simran, you must explain exactly (and not just with these little 6-line replies) what you've tried and what exactly isn't working. Are you getting gibberish on the ports? Are you just getting nothing? Does Hyperterminal report that the ports are in use? Have you tried a Linux live CD? If not, then *why not*?

Throw us a bone here!
