Re: [gpsd-dev] [PATCH] [log.chk] [TPV timing] implement $GPVTG message, and proper timing for output "TPV" messages

[teyrana]

Hey, guys -- 

We've implemented the $GPVTG message, and I wanted to get the list's opinion on what the proper behavior is for emitting messages on $GPVTG vs storing and waiting.  ( I've attached the .log.chk)

The intended (/implemented) behavior was for VTG to populate, but not trigger output.

This sample input is relatively sparse, to illustrate the effects of the VTG message:  the file only includes GGA, VTG, ZDA, and HDT messages.

Cheers,
-Dan

p.s. I ran into the list's size limit, which is why I tried to inclcude
