Only the device name changes and that's picked by the OS, not by us. So if before you did a gpsbabel -i garmin -f com3: -o gpx -F blah.gpx to read your waypoints from the garmin on com3 and write them in a gpx file name blah.gpx you can now gpsbabel -i garmin -f /dev/ttyUSB0 -o gpx -F blah.gpx only the device name changes. Some Linux systems don't always use ttyUSB0 so literally, but that's where I'd start. You may have permissions issues about opening device nodes as a user, but that works exactly the way UNIX permissions have worked for 50 years and isn't really a GPSBabel issue. Enjoy. RJL |
