uWAVE_Example_2.ino

/* 
 *   Necessary hardware:
 *      - Arduino UNO board
 *      - uWAVE underwater acoustic modem
 *      
 *   Connect uWAVE's TX wire to Arduino's PIN 2
 *   Connect uWAVE's RX wire to Arduino's PIN 3
 *   Connect uWAVE's CMD wire to Arduino's PIN 4
 *   Connect uWAVE's GND wire to any Arduino's GND PIN
 *   Connect uWAVE's VCC wire to Arduino's 5V PIN
 *   
 *   Connect Arduino board to a PC with USB cable
 *   
 *   If you have another uWAVE modem, turn it on and make sure its tx and rx channels IDs set to 0
 *   
 *   Open Arduino IDE
 *   Open this scketch in the IDE
 *   Open Port Monitor in Main menu -> Tools -> Port monitor
 *   
 *   Program your board
 *   
 *   Now you can use Arduino IDE's port monitor as a Chat terminal to chat with another uWAVE modem,
 *   which is suppose to be connected either the same way with another Arduino board or via UART-USB converter
 *   to a PC with any terminal software intalled.
