Hi all, My experience with the OS telling me what the OS is doing is not good. Of course there are 'reasons' for whatever OS behaviour! But generally OS numbers about OS usage are in my experience, total garbage.
I find it better to put a bit out to the parallel port and measure what is going on with an o-scope. 1 = busy, in linrad, whatever; 0 = in OS (whatever that means). There are many parallel port bits so they can allow one to time various routines, etc. If you do do this experiment, be prepared for the REAL surprises!!
