+  Software serial multiple 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), RX to pin 6(TX)
+ * Second serial device's TX attached to digital pin 8(RX), RX to pin 10(TX)
+
+ 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
+

+ This example code is in the public domain.
