Has anyone done anything like this with STREAMS-oriented tty drivers?
It seems to me that windows/multiple screens would be relatively
easy to implement by just PUSHing an appropriate module onto the
stream that controlled your physical terminal that kept track of
what was on your (physical) screen at all times, similar to curses.

It could also be handy to have a `virtual' screen of, say, 66 lines,
allowing one to scroll both up and down.

The more I think about it, the more I could do with a STREAM-based
tty driver.  Now all I need do is figure out how to get one...
