I will be beating myself up over this for a long while - that was
just plain stupid! Especially for me who has a lot of experience
wiring up a whole variety of RS232 devices - GRRRRRRRRRRRRR!
ABout that scope, I am going to post another thread about it.
Thanks!

I spent much time of good hard thinking (and soldering) over that,
because
it can get really confusing with the what relative to what things.
I usually end up making a schematic with arrows ;-)
Anyway, it is working now, so stop hitting yourself, you fixed it!
Now wasn't that MUCH easier to figure out than even a tiny mistake
in
software? Thought so!
If your scope was operating(-ed) properly you'd see something
arriving at
the transmit pin of the avr when you send with the PC and start
scratching
your chin.

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!
