garminctl 1 08 Oct 2006 garminctl control the modes of a Garmin GPS garminctl -? -h -n -b -D debuglevel -V serial-port garminctl can switch a serial Garmin GPS to NMEA or Garmin Binary mode. On exit it leaves the serial port set to the proper baud rate. This program is not for use with Garmin USB devices. Those are permanently set to Garmin Binary mode. You will probably need to be root to run this program, as the serial device it uses is normally privileged. The program accepts the following options: -? Display program usage and exit. -b Force GPS into binary mode. After the GPS resets itself autobaud to the new speed. Binary mode is always 9600 8N1. -n Force GPS into NMEA mode. After the GPS resets itself autobaud to the new speed. -h Display program usage and exit. -D Set debug level. -V Display program version and exit. The logic for hunting the GPS's baud rate is vulnerable to various sorts of RS232 flakiness. If it hangs for longer than a few seconds, kill the program and restart. gpsd8, gps1, libgps3, libgpsd3, gpsprof1, gpsfake1, gnuplot1. There are plans to merge this program with other GPS-type-specific control utilities. Similar functionality will be available, but name and invocation optins may be different. Gary E.
