Hi,

Something odd is happening.
I've connected a garmin 18 lvc to a pc.
The system has a kernel with pps support and i verified it comes in:

root at hoei:/home/folkert# cat /sys/devices/virtual/pps/pps0/{assert,clear}
1372528130.997131540#54
1372528131.097120120#54

I'm running gpsd and it says the gps has a fix and it also has all
appropriate devices open:

gpsd      27762           nobody    7u      CHR               4,65 0t0 
1144 /dev/ttyS1
gpsd      27762           nobody    9r      CHR              251,0 0t0 
82440 /dev/pps0

gps is started with '-n'

ntpd is configurated to listen to the shared memory segments:

server 127.127.28.0 minpoll 4
fudge  127.127.28.0 refid NMEA
server 127.127.28.1 minpoll 4 prefer
fudge  127.127.28.1 refid PPS


Don't you need this for PPS?

server 127.127.28.0 minpoll 3 prefer
fudge 127.127.28.0 time2 0.275 refid NMEA
server 127.127.22.0 minpoll 3
fudge 127.127.22.0 refid PPS
