You mentioned using the replacement serialpps.sys driver. Keep in mind that the easiest way to use this with a PPS-enabled GPS connected via serial is to configure only the NMEA driver (20) and leave out the PPS/atom driver (22). The details depend on which version of ntpd you're working with, but the NMEA driver is capable of using PPSAPI to get high-quality PPS timestamps from serialpps.sys, and in a single- driver configuration, there is no need for a separate prefer source. If you do choose to configure both drivers, make sure NMEA isn't attempting to use PPSAPI and leave that to the PPS/atom driver alone, and add prefer to the "server 127.127.20.1" line. Cheers, Dave Hart P.S. Very little of the code in ntpd is "Dave Hart code".
