Dave, et al,


My most humble apologies, In summary I tried windows ntpd on another box and PPS works as it should.

I am now getting pps tally and GPS_NMEA(1) PPS_RELATE_PHASE in debug.

Before It worked the first box joined the GPS sentences together, not good.

So I ended up using an identical box to my freebsd ntp server and it works perfectly.

This is where I wanted to be! As they say in America, Dang!


Anyway, I will confirm by trying drives in other systems but it seems a serial port problem with HP servers.

So far I have tried

DL360 G1 - PPS relate none
DL360 G5 - GPS sentences joined together.

The boxen ntpd works fine on is a pair of old HP procurve 760wl wireless lan controllers.
These have a pc system board with an intel P4 celeron and hardisk etc. basically a rack mount PC.

As I said I will try the same model DL series but with different hardware and see if PPS works.
I do hope it's not a design problem with the HP servers.


Many thanks,
Mark
