The logs, once pulled off the device are nmea. I can deal with those OK using gpsbabel, etc. Pulling the logs off the device requires some kind of command interaction that is buried in a Windows program. I could not get gpsd/sirfmon to do any thing useful. Looking through the output from strings data_load.exe I did find these format strings: $GPGGA,%02d%02d%02d.000,%.2d%07.4f,%c,%.3d%07.4f,%c,%d,00,,0.0,M,0.0,M,,0000 $GPRMC,%02d%02d%02d.000,A,%.2d%07.4f,%c,%.3d%07.4f,%c,%06.2f,15.15,%02d%02d%02d,,,E $GPGGA,%02d%02d%02d.000,%.2d%07.4f,%c,%.3d%07.4f,%c,%d,00,,%06.1f,M,0.0,M,,0000 so figuring out the serial protocol may be a bit ugly. If you have any pointers, that would be great. I tried using minicom and info from the man pages to manually talk to the device, but had no success. http://www.linuxjournal.com/node/7582/ Snooping the USB Data Stream was referenced from the site Ben sent. I'm hoping that will do the trick. -- Lloyd Kvam Venix Corp DLSLUG/GNHLUG library http://www.librarything.com/catalog/dlslug http://www.librarything.com/profile/dlslug http://www.librarything.com/rsshtml/recent/dlslug _______________________________________________ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/
