Arduino TPDD update

I tried to change the RS-232 Shifter to provide the signals that my 102 needed, but that didn't work out.  So I made a null modem cable based on the Club 100 documentation.  So that's all soldered and looking good.

However, testing completely failed.  Using the new cable, no tests worked and no communications at all.  Going back the old cable, my tests worked.  So the new cable is the problem.

But I checked continuity on all the lines and everything was correct.

I'm stumped right now.
