Ive been scouring the pages here trying to find a solution, but nothing seems to work for me at the moment.
-------------
I first followed the phouqueq tutorial on making a simple jtag checked all connections before firing up the IRD and trying it out...no go.

I went through the makeshift troubleshooter by ozz2001 and found that only the first few solutions were applicable to me because I couldnt even get JKeys (latest build 299_26) to detect anything.

I attempted editing the DEF file to add my IRD...no go.
**randomly the IRD drop down box did become selectable once and i was able to select 3900 but got a peek error, after reattempting to read i wasnt able to get any further than 0xFFFFFFFF
I came across another layout of how to wireup a JTAG and tried that as well...no go.

I tried connecting directly to the serial port from my ird, cables run about 6 inches, and through an extension cord ~3ft...no go.
I tried on 3 different computers, first checking settings in Device Manager, then checking the BIOS on each to make sure they are BiDirectional/SPP, also making sure that the port addresses were set correctly...no go
-------------
the only thing about the setup that may be the cause of the error is the grounding. I have it running from pins 18-25 to the ground pad of the jtag, even tried running an additional line to a screw on the case. any suggestions as to where to ground?
ive tried on 2 different 3900s, both with same results. i noticed the green light doesnt power on anymore, but skimmed through a fix for this that I will get back to later. i am under the impression that i can still read/write the tsop under these circumstances
all assistance would be greatly appreciated. have an atmega on the way and would like to get this project going!! thanks in advance.
