GRRRRRRRRRR. Stupid, Stupid, Stupid!
I see where I messed up and it is one of those "I couldn't be any
more stupid if I cut my head off" things!
I made the non-working board from the working circuit - copy and
paste and a little tweaking.
For the connection to the AVR I followed the legends on the working
circuit board which has the two signals marked Tx and Rx. For that
board, it was telling me what the pin does - relative to the MAX232
not the AVR!
So, I drilled out the traces on the Tx and Rx signals betwen the AVR
and the MAX232, wired in some cross-over jumpers, connected it all
back up again and viola! Things work - well, atleast my RS-232
tester thing is flashing the right lights.
GRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRR
Thump, thump, thump, thump, thump.... (sound of kicking self in butt)
