i was wondering whether it might not be useful
for the terminal handler (win/rio) to print a prompt
of some kind when it got a read request on /dev/cons.
that way you get a prompt for all other programs too
(e.g. db(1)) without the clutter of isatty() and the like.

only problem is you wouldn't be sure quite which
program was asking for input. hmm, maybe not quite
such a good idea after all.

  rog.
