The negative saw-tooth field _is_ the cure. As long as you apply the correction, you are in pretty amazing shape. The trouble is when you do not apply the correction. Curing that would take more involved hardware than the oncore has, so firmware access would not help you. The more involved hardware is what the CNS Clock is all about as far as I can tell. If you feed a PRS10, and it's firmware is new enough, you just need to read the serial data from the oncore, and send the correction to the PRS10 and everybody are happy. -- Poul-Henning Kamp | UNIX since Zilog Zeus 3.20 [EMAIL PROTECTED] | TCP/IP since RFC 956 FreeBSD committer | BSD since 4.3-tahoe Never attribute to malice what can adequately be explained by incompetence. _______________________________________________ time-nuts mailing list [email protected] https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts
