I have a Trimble Acutime Gold GPS[1] and I got some problems installing that
device in both FreeBSD and Linux. That GPS has an USB Interface with FTDI
support.
FreeBSD configuration:
1) kldload uftdi
2) dmesg:
ucom0: <FTDI Dual RS232, class 0/0, rev 2.00/5.00, addr 2> on uhub3
ucom1: <FTDI Dual RS232, class 0/0, rev 2.00/5.00, addr 2> on uhub3
3) ln -s /dev/cuaU0 /dev/palisade0 (I tried cuaU1 with no success)
4) ntpd.conf configured without event polling [2]:
# The Primary reference
server 127.127.29.0 # Trimble Palisade GPS.
# Set packet delay
fudge 127.127.29.0 time1 0.020
# and set flag2 to turn off event polling.
fudge 127.127.29.0 flag2 1
First problem:
For some reason event polling (fudge options commented) does not work. The GPS
turn unreachable.
Second problem:
My GPS is a falseticker:
$> ntpq -np
remote refid st t when poll reach delay offset jitter

I appreciate any help.
