[avr-gcc-list] Butterfly RS232?

[Mike Young]

Looking at the schematic for the Butterfly, it's not readily apparent how it 
manages to translate levels for outbound data. The docs seem to say it's 
supposed to work, but my primitive understanding of electronics matches the 
results: non-receipt of "transmitted" data. It could also be my primitive 
understanding of the mega169's usart that's at fault. Is the ported gcc 
Butterfly usart code supposed to work?

Many thanks.
Mike.
