I was using ntp-4.0.98a.
After reading your message I understand the source of my trouble.
I downloaded and compiled ntp-4.0.98d
This ntp-4.0.98d is now working OK.
I normally read the -Stable Mailing List, but missed your message
because I unsubscribed temporarily to reduce email while travelli
You don't say which version of ntp you are using. If you are using something
older than ntp-4.0.98b, please read the message I sent on Oct 16 to
freebsd-stable with the subject line:
HEADS UP: ntpd users
If you are using ntp-4.0.98b or later tell me and I will look into it,
because it is working
SUMMARY:
ONCORE GPS Clock source for NTPD on FreeBSD was working
with 3.3-Stable (Oct 8 1999). With 3.3-Stable (Nov 4 1999)
NTPD fails with a 'time_pps_setparams: Inappropriate ioctl for device'
message. It seems that '/dev/pps' may have been changed to '/dev/lppps0'
