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
