 * The driver core will do all the protocol handling and provides
 * the following (interface independent) parts already
 *    upsdrv_updateinfo()
 *    upsdrv_shutdown()
 * Communication with the UPS is done through blazer_command() of which
 * the prototype is declared below. It shall send a command and reads
 * a reply if buf is not a NULL pointer and buflen > 0.
 * Returns < 0 on error, 0 on timeout and the number of bytes send/read on
 * success.
