This is the configuration for the first one

# PPS & NMEA
server 127.127.20.0 mode 18 prefer minpoll 4 maxpoll 4
fudge 127.127.20.0 flag1 1 flag2 0 flag3 1 time2 0.400

The other machine has

# NMEA only
server 127.127.20.0 mode 2 prefer minpoll 4 maxpoll 4 iburst
fudge 127.127.20.0 time2 0.315 flag1 0 flag4 1

# PPS (PPS in kernel)
server 127.127.22.0 minpoll 4 maxpoll 4
# This is for kernel PPS
fudge 127.127.22.0 flag2 0 flag3 1

Many thanks!

Cheers,
Miguel
