I think this actually refers to the "Page Mode" of a "tty" window.  Strictly
speaking, that is in Suntools rather than in SunOS itself, although there
may be some kernel support involved.  It certainly works well, and I see
no reason why such a scheme couldn't be much more widely adopted.

Unfortunately, the Suntools implementation is incomplete.  It works fine as
long as the window is connected to a local process, but if I rlogin to
another node it acts as if I had disabled page mode and I have to fall back
on "more" or ^S/^Q (which do still work).
