Looking at the schematic diagram for the AVR-P8B prototype board, I noticed that the RS-232 interface circuitry is a little different than I expected.
The transmit circuit uses a transistor and appears to be inverting, as I expected. However, the receive circuit has the AVR pin connected to the RS-232 line *without* any inversion. Is this correct?
Thanks,
Eric
