Win2000 is the main interest right now.

What problem do you hope to avoid by not using 'polling
and timeouts'? (Note that if you specify a sizable
read timeout, you're closer to being interrupt-driven
than you are to what is traditionally called 'polling'.)

Peter,
Thanks for the reply. I'm working on a s/w test program using python
code. Com1 and com2 play a part. The problem is that the python code
has a lot of work to do..and the results from the hardware under test can
come from either com1 or com2..at any time. It may be a few milliseconds,
or several seconds, sometimes minutes, before a response is expected.
I'm not sure what timeout value I'd use. Using threads, and re-loading the
timeout values on the fly may be a solution, but I'm not experienced with
threads..and was hoping to avoid them.

NOTE: you MUST set the hardware stack size in Bascom's Options - Compiler. '. Chip = 40. Enable interrupts on timer 1 overflow and both output compares. This Dumps Strings Over The Serial Port To Indicate Why We Recently.
