An ugly fix

It is ugly, but it works:

I soldered leads to a 1-gate logic inverter.  This wasn’t easy because the part is so small.  Then connect it to 3.3v, GND, and the RTS line coming out of the WiReach.  Then I cut the RTS trace on the bottom of the board.  I connected the output of the inverter to the input of the line driver IC.

Some Kapton tape holds it all in place.   It is a really terrible hack, but it works.  Hardware flow control works as expected, now.

I’m going to design a version 1.1 of the board that includes the inverter.  Also I can remove the extra GPIO/Reset stuff since the “power good/reset” circuit works.
