Thanks for the information. I tried what you described and now the
system is working on PPS with only the "20" driver. But, I'm confused.
I thought you had to use the "22" driver to get PPS.
I'm trying various options of NTPD_USE_INTERP_DANGEROUS, flag3 on the
"20" driver, and process priority to see what has any effect.
(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.)
