We have verified the frequency and have the corresponding value in 
the ISP program (14745).

That's what we are using as well. 

Last night we were able to get it to work once, but today - we don't 
seem to be having any luck. We were hoping to see if there was 
something we were missing. But it *seems* like we've got everything 
covered. I wonder if it's something on the PC side. All the other 
designs (the ashling board, your board (Leon) use the MAX3232 
converter). We didn't have that on our board, and so we connected our 
PC to the ashling board and then jumpered the Rx and Tx pins to our 
board. (worked once or twice last night but not today). 

Ah, life's mysteries!  Anybody available by phone that we might be 
able to confer with? We'll pay for the call, of course!

Thanks,
Bryan
