I am running 4.2.7p98-o and I am uncertain whether or not PPS is working.
Under windows device manager I can see drivers for the port:
Serenum.sys
Serial.sys
Serialpps.sys
Serenum.sys & Serial.sys have a green tick next to them.
In event viewer, when starting ntpd I can't see any reference to PPS.
My relevant ntp.conf:
server 127.127.20.1 minpoll 4 maxpoll 4 mode 24 prefer # NMEA serial port, 16 = 9600 baud, 8 = $GPZDA
fudge 127.127.20.1 flag1 1 time2 -0.4781
the time2 fudge is the only way I can get the HP 58534 GPS timing antenna not to be marked a false ticker.
The loopstats all look good, but I am curious to know whether PPS is active or not.
Many thanks,
Mark
