Yeah - so if you want to talk between them via serial, you need to
leave the jumpers in place.

i2c-io.hex doesn't print anything on the serial port. I'd recommend
trying Flash-LED.hex. It flashes the LEDs once per second and writes
stuff to both UART-0 and UART-1 (at 38400 baud).

I use either the sertest program or serial-log program.
