I'm starting to get it, chan_kern is the place to start to understand
what happens when a read or write irq goes off. I don't think there is a
short-circuit mechanism for hooking up the internal fd for a tty
directly to an fd within a channel driver without breaking this design.
So what if I modified port_task_proc to copy the incoming data in the
appropriate direction? I'll give that a try next.

Jeff, please, what does "winch" stand for?

And also, if I submit some patches that just contain brief source
comments about how things work will you accept them? I notice you don't
use them much.
