I was considering the possibility of combining both a software and hardware combination such that software would provide for pre-and post delays if the required delays were outside the abilities of the hardware. Am yet to create an implementation of this though, and I'm still pondering on how to cleanly communicate the abilities between the general serial-core and the lower level hardware interface. > > > So I suggest not to mix hardware and software direction control > as the same issue.

I may, if I get my act together, use your patch as a basis for demonstrating a software/hardware combination (but don't hold your breath!).
