+ Software serial multple serial test
+
+ Receives from the two software serial ports,
+ sends to the hardware serial port.
+
+ In order to listen on a software port, you call port.listen().
+ When using two software serial ports, you have to switch ports
+ by listen()ing on each one in turn. Pick a logical time to switch
+ ports, like the end of an expected transmission, or when the
+ buffer is empty. This example switches ports when there is nothing
+ more to read from a port
+
+ 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
+
+ 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).
+
+ created 18 Apr. 2011
+ modified 25 May 2012
+ by Tom Igoe
+ based on Mikal Hart's twoPortRXExample
+
+ This example code is in the public domain.
