Thanks! I know that you said it was easy, which is why I went the
OpenBSD route - didn't know it would be that easy though.
So, just to confirm, I need to change the rc.conf line to this, based on
the GPS being connected to the first serial port, with PPS on the
carrier detect pin:
nmeaattach_flags="-t dcd /dev/cua00"
Cheers
