Warner, Thanks so much for your response. This is really a case where I'm a bit over my head! I thought on a a "busy" machine, there was a fundamental "no uppper bound" on the wait on a sleep; independent of the Hz? Not real-time blah, blah, ...... I am trying to understand if a driver "sleep" gets special attention (i.e higher "priority") so that I see less slop in the timing. Of course, I could hack up a driver and try some tests, but wanted some advice before diving into that pool. Thanks again. -- Len
