/* 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.
*
* You can also just use the serial terminal to send and receive
* APRS packets, but keep in mind that several fields in the packet
* are bit-shifted from standard ASCII (so if you're receiving,
* you won't get human readable callsigns or paths).
*
* To use the KISS example with YAAC:
* 1. open the configure YAAC wizard
* 2. follow the prompts and enter in your details until you get to the "Add and Configure Interfaces" window
* 3. Choose "Add Serial KISS TNC Port"
* 4. Choose the COM port for your Arduino
* 5. set baud rate to 9600 (default)
* 6. set it to KISS-only: with no command to enter KISS mode (just leave the box empty)
* 7. Use APRS protocol (default)
* 8. hit the next button and follow directions to finish configuration
