garminnmea [Drivers] Device driver for the Garmin geko 201 handheld GPS unit. Interacts with the unit by speaking NMEA over a serial line. As such, this driver may work with other Garmin units, and (likely with some modification) other NMEA-compliant GPS units. The driver may also attempt to read DGPS RTCM corrections from a multi-cast network address, and forward these corrections to the GPS unit. The dgps_server utility may be used to gather and broadcast the DGPS RTCM corrections.
