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.

Is there any other way to watch the signal to see if it's reaching the serial port correctly?

I've used radioclkd2 to setup my pulse stretcher and pps
ouput pulse length from MSF. I wasn't able to do this with
any accuracy using a scope. Intended purpose is decode of
DCF77 and MSF which it does very well here from both Linux
or NetBSD.
