[gpsd-users] 1 PPS and Ubuntu11.10 serial port problem

[Robert Livingston]

Receiver is Trimble Resolution T; using 1 PPS output for NTP.

The receiver connects, is recognized as TSIP and transfers time/position 
data correctly.  However, debug reports the device as offline (briefly) 
after every packet.  Could this be related to the two different baud 
rates reported during the initialization?

Thanks for any clue.
