FUNCTION process_packets

DESCRIPTION
  This function is the main loop implementing the DMSS Async Download
  Protocol.  It loops forever, processing packets as they arrive.

DEPENDENCIES
  All necessary initialization for normal CPU operation must have
  been performed, and the UART must have been initialized, before
  entering this function.

RETURN VALUE
  This function does not return.

SIDE EFFECTS
  None.
