Well there's your problem...

In your devfs.conf you should have:

link cuad0 gps0

Before doing that you can just make symlinks yourself to tinker around. Then
edit the devfs file to retain the info when you reboot.

cuad0 = com1
gpsX = the last number in the below 127.127.20.x line

NTP assumes that if there is a PPS signal it will be on Pin 1 (DCD?).

Then in your ntp.conf file:

server  127.127.20.0 minpoll 4 prefer
fudge   127.127.20.0 time1 0.0

time1 you might need to adjust depending on the length of your cable, if not
then you can exclude the fudge line. You should not need to set flag3, you
could spend weeks reading all the posts and the for / against setting it.
