[FOSS-GPS] RTKNavi hanging

[dannym at austin.rr.com]

OK, I think I've got it... I had NMEA going to the port on the direct USB link to the computer.  I'm not sure why this would be a problem, AFAIK RTKLib recognizes NMEA and UBX binary and only accepts the binary.  The extra bandwidth for the unneeded data might overrun the buffers though, and might only do so when there's enough satellites overhead?
