00057 * The prints are sent to the terminal window (9600, 8n1).
00058 * The program initializeds the LED to blue-green.
00059 * If the program is successful at reading the hardware ID
00060 * then it prints out a successful message, and if not, then
00061 * it turns on the red LED.
00062 * To run the program, drag and drop the .bin file into the 
00063 * DAPLINK folder. After it finishes flashing, cycle the power or 
00064 * reset the Pegasus after flashing by pressing the button on
00065 * the Pegasus next to the battery connector or the button
00066 * on the MAXREFDES100HDK.
