It still didn't fix my communication problem but gives you something to check..

I have 0.00 ohms on that link. So that should not be the problem.
Looking at the board under the magnifier ... I am pretty embarrassed by the re-soldering that I did. It looks like pin 1 on U4 is a cold solder. Perhaps I should go over the board again with a soldering iron and try to make it a bit more of an example of what you SHOULD do instead of the present state - an example to AVOID.
It's been years since I soldered anything ... but it should come back with practice!
