OK. Couldn't get the Oncore unit to work in any way
shape or form. I bought a DB9 LED tester like this:
Had PPS going to pin 1, DATA OUT to pin 2, and DATA IN to pin 3.
Bought a Garmin GPS 25-LVC, put it in an enclosure, commented
out the Oncore driver and added to ntp.conf:
# Garmin / PPS driver:
server 127.127.20.0 prefer
fudge 127.127.20.0 refid GPS
Checking the status:
# ntpq -c pe
remote refid st t when poll reach delay
xGPS_NMEA(0) .GPS. 0 l 15 64 377 0.000
Looks like it is being read, but is off by quite a bit. Any ideas on
to get it to behave?
