+
+ Receives from the two software serial ports,
+ sends to the hardware serial port.
+ Based on Mikal Hart's twoPortRXExample
+
+ 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 10(RX), RX to pin 11(TX)
+ * Second serial device's TX attached to digital pin 8(RX), RX to pin 9(TX)

+sentence=Enables serial communication on any digital pin.
+paragraph=The SoftwareSerial library has been developed to allow serial communication on any digital pin of the board, using software to replicate the functionality of the hardware UART. It is possible to have multiple software serial ports with speeds up to 115200 bps. This version also supports devices without PCINTs using regular interrupts instead.
