There is already code that 'turns up' the system clock frequency (I believe the pc-audio code to be exact) to (I think) 10KHz so you could do similar and get 100uSec time, but the question is: do you want to be doing other things while waiting for this timeout, or just spinning awaiting it's completion? julian > > Thanks > -Chitra Venkatramani > (chitra@cs.sunysb.edu) > >
