Anybody have a clue on why my GPS_NMEA continues to show the following?
godzilla# ntpq -p
remote refid st t when poll reach delay offset
jitter
==============================================================================
GPS_NMEA(0) .GPS. 0 l - 16 0 0.000 0.000
0.002

Now I know I can see data from /dev/cuau0 (a /dev/gps0 link points to
/dev/cuau0) when I cat the port.
But when I start up the NTP daemon, I get nothing.
godzilla# cat /dev/cuau0

When I run ntpdc -c kern I get the following:

Any idea what could be the issue? I figure its with FreeBSD, because when
I had my Sure Electronic's box
hooked up to a "kfreebsd" box, I got reachability, delays, offsets,
jitters, etc. I'm just not sure what is
missing or incorrect.
