Yes, thanks, I just transposed the letters when typing my email,
and they are simply a text field irrelevant to operation anyway.
Since posting, I've read some info suggesting that WinXP is a great
deal different from Win2K under the hood, taking a lot more resources.
One other experiment that I need to try besides recording the exact
timecode= message on the WinXP machine is to hook my Acutime 2000
to the offending laptop and see if it causes the same behavior as
the Praecis. I have plenty of equipment, but not a lot of time to
troubleshoot problems.
Incidentally, my Win2K laptop (which has no problems with the Praecis)
when configured to use the Praecis on COM1 as a server and a RH9 Linux
box having an Acutime 2000 as another server shows the two clocks
agreeing to under 200 us, e.g. reporting offsets like 0.990 and 0.870,
respectively. I didn't realize sub-millisecond timing was possible
in Windows at all. Not bad.
Off topic: I've also had problems with Digi brand serial drivers
working fine on Win2K Dell laptop and WinXP Dell desktop, but failing
on WinXP Dell laptop. Conclusion: use Win2K? Works in the short
term, but M$ will stop supporting it someday. Alternate conclusion:
don't trust Dell laptops? Less likely to be the problem, I think.
Thanks for any hints.
Best regards,
Chris Burian
