I think this is the bug I reported last year after Field Day. With
CT-DOS 9.90 on a 386sx
running DOS 6.22, I experienced significant slow down of the PC clock.
Here is Ken's response:
I completely re-wrote the interrupt handler for the counter timer chip
in
order to support CW sending from the paddle. The old scheme set up the
counter timer to interrupt at each baud interval. The new interval
interrupts every millisecond.
I don't think I'll ever get around to investigating 386SX in this
regard.
This would agree with my experience that earlier versions of CT-DOS 9.x
didn't have
clock slow down problems. I've never bothered to see if it affects 486.
CT-DOS
and CTWin have always shown the correct time on my P90 computers, even
when CT-DOS is
run under Win98SE.
