Ah, I misunderstood then, sorry. I thought you meant to suggest the use of interrupts for asynchronous operation - just the opposite of what we have now with bitbang-all-the way. Yes, that makes sense as long as the bit-banging doesn't take too much time. (How much time does this interrupt handler actually take ?) - Werner
