Besides the Trimble devices, the other devices include the Z3801, Z3811/Z3812 (aka Lucent KS2xxxx), Trimble/Symmetricom "UCCM" GPSDOs, Oscilloquartz STAR-4 GPSDO, NEC GPSDO, and NMEA, Ublox, Motorola, Venus, SIRF, NVS, etc GPS receivers, and GPSD. It is probably compatible with the Z3805/Z3816/HP53xxx devices but has not been tested with them. In most cases it can auto-detect the device type and serial port configuration. The code is compatible with Windoze, Linux, and macOS. Runs well on the Raspberry PI... --------------- > Would have been great to have the TBolt and Z3801 working.
