/**
 * Sends DEADBEEF out the UART pins.
 *
 * Written to put the EEPROM argument to rest.
 * It creates code that LOOKS broken, but is so broken it actually 
 * works.  EEPROM data apparently needs to be 16-bit aligned for some 
 * reason, and the useless 'retlw' instruction that doesn't even belong 
 * in EEPROM makes it line up just right.
 *
 * So in the end we get DEADBEEF out of the EEPROM, character by 
 * character, despite it all.
