 * This component checks the functionality of the device and sends a
 * report message over both the UART and the radio.  It should be run
 * with the java program hardware_check.java, which interprets the
 * report messages. To test the radio, program a second mote with
 * generic_base_high_speed, which will forward the received radio
 * packets to the java program for interpretation.  This program also
 * prints out he serial_ID for the ID chip of the mote.
