| This driver supports GPS receivers with the $GPRMC, $GPGLL, $GPGGA,
| $GPZDA, and $GPZDG NMEA sentences by default.
| The driver expects the receiver to be set up to transmit at least one
| supported sentence every second.
| Specific GPS sentences and bitrates may be selected by setting bits of
| the 'mode' in the server configuration line:
| server 127.127.20.x mode X
| bit 0 - process $GPMRC (value = 1)
| bit 1 - process $GPGGA (value = 2)
| bit 2 - process $GPGLL (value = 4)
| bit 4 - process $GPZDA or $GPZDG (value = 8)
Any one of the supported sentences will work.
