1G Diagnostic port issues?

[lookinfor400hp]

#1- I searched and found nothing on this. Everything seems to be 2G related.

#2-Ok , so I have tried all three of my Palms (old Palm IV, and two M130's)

Still unable to log with my new pocketlogger setup, it displays connection error. I have used two different serial cables for the M130's with the same error (one eBay cable and one I bought through Pocketlogger). They hotsync just fine, but still unable to log. Could this be a data port problem?

Keep in mind my IV with mmcd worked fine before I switched to Pocketlogger. Short of attempting to reload mmcd and trying it that way I don't know what else to do.

How can I check my diagnostic port to see if its the culprit? Is this something that anyone else has gone though?

FYI

I just swapped in my working non-EPROM ECU with the same results. So I believe I can rule out the ECU as a cause.
Any ideas where to look. I have been digging though my factory manual with no luck as of yet where the diag port might be faulty.

Its probably your software, why dont you want to go back to MMCD?

If MMCD works then I would say the port is fine. I would say you have a software problem. The diag port sends the same data no matter what program is being used to read it.

Well , I tried my old palm with mmcd and I get a ECU comm error.
I get that error with all three palms (mmcd and pocketlogger) and both ECU's.
Spent all night trying to figure it out.Still a no go.With pocketlogger its a "connection error" with mmcd its says "serial port in use"
How can a diagnostic port go bad???WTF
When I get home today I will go back over my manual and trace out the diag port and follow back to all the components there and I guess I should find something....
