What os? What accuracy are you shooting for? In linux I have enabled
high rez timers and written some code to put out a carriage return "on
time" on a serial port. Seems like sub 100 microsecond was the norm. I
could probably scrounge the data. Or are you just asking if there is a
way to turn something on? If so, I don't know about that.

Subject: [ntp:hackers] Output disciplined PPS from RS-232?
Hello list,
May be some of you have more experience on PPS than me (almost none), I
would like to know if is it possible to output a PPS from a disciplined
(pps-kit) stratum 1 server on the RS-232 interface, the scenario is
this:
a ntp server (stratum 1) with a gps reference clock, and a pps input
from the same gps disciplining the clock via pps-kit patch...
Thank you very much in advance...
Best regards,
--
Fer
