Believe me you are not the first one to do this!
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!
