[time-nuts] More from the obsolete gps file: oncore nmea

[mike cook]

Norm,
   I am not sure about the M12+ as I think that had NMEA support from 
the start. GT+ also does but there are GT firmware versions that do not 
support NMEA. Are ou sure it is a GT+ . Motorola give GT plus model 
numbers R3211G11x, R3111G11xn. Does that fit?  If you use the ID 
command, @@CjC<cr><lf> , you will see the firmware version.  I found a 
synergy systems tech note indicating that you  need 2.x + to use NMEA if 
it is a GT.  GT with lower versions gives your symptom..
