The circuit:
Two devices which communicate serially are needed.
* First serial device's TX attached to digital pin 2, RX to pin 3
* Second serial device's TX attached to digital pin 4, RX to pin 5
* First serial device's TX attached to digital pin 10(RX), RX to pin 11(TX)
* Second serial device's TX attached to digital pin 8(RX), RX to pin 9(TX)

Note:
Not all pins on the Mega and Mega 2560 support change interrupts,
