It feels like I must be missing something here, running with -d I can
confirm that PPS doesn't appear to be working - after enabling flag3 as
well.
25 Feb 13:53:21 ntpd[75656]: 0.0.0.0 041d 0d kern PPS enabled
25 Feb 13:53:21 ntpd[75656]: 0.0.0.0 042d 0d kern PPS no signal
..
Is there any other way to watch the signal to see if it's reaching the
serial port correctly?
