/*
This example is for Series 2 (ZigBee) XBee Radios only
Receives I/O samples from a remote radio.
The remote radio must have IR > 0 and at least one digital or analog input enabled.
The XBee coordinator should be connected to the Arduino.
 
This example uses the NewSoftSerial library to view the XBee communication.  I am using a 
Modern Device USB BUB board (http://moderndevice.com/connect) and viewing the output
with the Arduino Serial Monitor.    
You can obtain the NewSoftSerial library here http://arduiniana.org/libraries/NewSoftSerial/
