That is where I obtained the ppstest code and then later I

NetBSD list also suggested that I compare kernel traces on the two

differently than ntpd itself when it interfaces with the kernel. I
can provide traces to anyone that would like them for both the
pps-api test program and ntpd 4.2.6p3.

A shot in the dark, have you tried removing "flag3 1" to disable the
kernel PPS discipline?
Yes but ntpd still doesn't see the PPS signal on DCD with or without
flag3. So I'm lost on how to solve this problem. I know the PPS signal
is there on the wire, I know DCD is being asserted and cleared. I know
the test code can see it but for some reason I just can't make ntpd see it.
