Hi David!
I tested with your dll:

The PPS was not detected, I don't know what I did wrong.
Here is the content of my ntp.conf:

server minpoll 2 maxpoll 2 mode 89 prefer
fudge time2 0.125 refid NMEA
server minpoll 2 maxpoll 2 true
fudge refid uPPS

FYI, the pagehttps://kb.meinbergglobal.com/kb/time_sync/ntp/ntp_for_windows/using_pps_signals_on_windows  was updated today, there is a new link to "serialpps-20120321-signed.zip".


It's not "my" DLL, but one provided by Meinberg IIRC.

If you use the PPS you /must/ mark one of your other sources as "prefer". Without that any PPS doesn't work.

I take it that my Serial Port LEDs program shows a flashing DCD (when NTPd is stopped)?

Good to hear that there is an updated link.
