Also, why doesn't the PPS show up in my status screen anywhere? I know
it's working, based on the graphs.

Ron:
Here are my ntp.conf lines I use for my SureGPS running under FreeBSD
plugged into Com Port 1 ( /dev/cuau0). I also create link (ln -s)
from /dev/gps0
to cuau0.

Hi Alby,
Thanks for the information. I tried what you described and now the
system is working on PPS with only the "20" driver. But, I'm confused.
I thought you had to use the "22" driver to get PPS.
I'm trying various options of NTPD_USE_INTERP_DANGEROUS, flag3 on the
"20" driver, and process priority to see what has any effect.
Sincerely,
Ron
