/* Hamshield
 * Example: KISS
 * This is a example configures the HamShield to be used as 
 * a TNC/KISS device. You will need a KISS device to input 
 * commands to the HamShield
 * Connect the HamShield to your Arduino. Screw the antenna 
 * into the HamShield RF jack. Connect the Arduino to wall 
 * power and then to your computer via USB. Issue commands 
 * via the KISS equipment.
