  Software serial multiple serial test

 Receives from the hardware serial, sends to software serial.
 Receives from software serial, sends to hardware serial.

 The circuit:
 * RX is digital pin 2 (connect to TX of other device)
 * TX is digital pin 6 (connect to RX of other device)

 Note:
 Not all pins on the Elbear Ace-Uno support interrupts,
 so only the following can be used for RX:
 2, 3, 4, 5, 8, 9
