Speaking of which: has anyone noticed the

	tp->t_char

field of the tty guys?  It's called "character temporary" which
doesn't mean much.  I can't see what it's used for.  In any case,
another problem with TANDEM mode is that when it sends ^S or ^Q,
it places them at the END of the outgoing queue!  It would be much
better if it placed them at the beginning.  Could tp->t_char be
used to hold a ^S?  If not, then perhaps another entry should be
added that could.  Of course, adding this would be a big pain in
the (uhhh...) drivers.  The other alternative is to move all of
the queued characters back to make room for a ^S at the front,
which would be ridiculous for large out queue lengths.
