On any platform, with flag1 1 for the NMEA driver, PPSAPI is attempted. If it fails, you will see the driver whinge to syslog. If it succeeds and PPS is working, you'll see 'o' tally code in the first column of ntpq -p output (PPS peer) rather than '*' (system peer). With flag3 1 (kernel hardpps, that is, kernel sync directly to PPS without ntpd involvement) you can check for PPS indicated in one of several similar outputs: ntpdc -c kerninfo ntpq -c kerninfo (requires recent 4.2.7 ntpq and ntpd) ntptime Cheers, Dave Hart _______________________________________________ questions mailing list [email protected] http://lists.ntp.org/listinfo/questions
