+ Receives from software serial, sends to hardware serial.
+ 
+ The circuit: 
+ * RX is digital pin 10 (connect to TX of other device)
+ * TX is digital pin 11 (connect to RX of other device)
+ 
+ Note:
+ Not all pins on the Mega and Mega 2560 support change interrupts, 
+ so only the following can be used for RX: 
+ 10, 11, 12, 13, 50, 51, 52, 53, 62, 63, 64, 65, 66, 67, 68, 69
+ 
+ Not all pins on the Leonardo support change interrupts, 
+ so only the following can be used for RX: 
+ 8, 9, 10, 11, 14 (MISO), 15 (SCK), 16 (MOSI).
