+ Receives from the main serial port, sends to the others.
+ Receives from serial port 1, sends to the main serial (Serial 0).

+ This example works only with boards with more than one serial like Arduino Mega, Due, Zero etc

+ The circuit:
+ * Any serial device attached to Serial port 1
+ * Serial monitor open on Serial port 0:
