Hi all,

I now have my USB GPS working at an acceptable level on both Windows and 
Linux using only NTPD.  I have the GPS server line set as prefer, but 
there are other server lines which poll the internet.  Sometimes, the 
system selects an internet clock rather than my GPS.  How do I force NTP 
to use my GPS if it's available, no matter what (within reason).  The 
only time I ever want it to select an internet server is if the GPS 
fails or is not plugged in.



(PS - If you email me and don't get a quick response, don't be concerned.
I get about 300 emails per day from alternate energy mailing lists and
such.  I don't always see new messages very quickly.  If you need a
reply and have not heard from me in 1 - 2 weeks, send your message again.)
