The simple solution is to set the option to output the time near the top of
the second.  Which is not the default. 

Is there any documentation for how to do that?  (Running a Windows program 
doesn't count.)

Does gpsd know anything about Venus chips?  I poked from gpsmon and it didn't 
get out of NMEA mode.  There was stuff on the screen, but it's not in the log 
file.

There used to be a web page of all the packages/chips and how well they 
worked.  Is that still around?  Should we add a slot?

Hal, Gary,

I searched for quite some time looking for a way using something other than Windows to configure this module.
Here is the only real attempt that I found.

https://github.com/r0ro/skytraq

I was unsuccessful in getting that code to do anything...

I have been working from that and have code that can guess the serial speed, set the serial speed, get the software version(s) of the module, get the CRC of the software.  Lastly and most important to me set when the NMEA message is delivered.

It's my non-programmer attempt to get something working that doesn't require me finding a Windows box simply to change a setting or two.

If there is an interest I can put it up on github or somewhere.

The docs do not directly state a command that changes when the NMEA message is delivered.  After some experimentation I've found that the 0x08 command will indeed do just that.

To the best of my knowledge the Venus 6 will only ever show up to gpsd as a NMEA device.  As such none of the related tools can change settings on the module.  I believe that it's either in NMEA mode or Skytraq binary mode.
