Someone that cares should roll the few important parts into gpsctl.

On my list, but not very high up.

Sure, at least it is a start.  Mostly gpsctl just needs to know
the binary to send, and the gpsctl can frame it in a packet with 
proper checksums.

What is the exact command that works for you?  That could be added
to the gpsd venus init string.

Here are the Venus 6 Binary docs:

IN the Windows program, I see "Set GPS Measurement Mode" and you set it
to "Sync to UTC Second when UTC Fix"

The message their Windows software sends is:

    a0 a1 00 03 3e 01 01 3d 0a 0d

But when I look in the Venus 6 docs, the 3e seems to have to do with PPS 
not measurement...

Nothing about 3e in the Venus 8 doc, but the Venus 8 ACKs that command.

Skytraq Binary mode is Venus Binary mode.  Same thing.
