Dale, there are not 8 variations. Don't start saying software vs.
hardware again, because the client doesn't get a choice on that, at least
not on a per-call basis.

Parport is supposed to be independent from the architecture. I'm not
saying it's perfect in that regard _now_ -- as Joerg pointed out, it's
very PC-biased. But independence is the aim, and so moving _toward_ the
hardware is counter-productive.

If you really want separate functions to do the transfer handshaking in
software rather than hardware, there had better be a _very_ good reason.
So far you haven't convinced me that there is. (You are welcome to keep
trying though.)
