I have an sh script that asks the user a question and reads
the answer into a variable in the usual method.  I want to
be able to flush the input buffer just before the read so
that any slips or double key bounces get ignored, rather than
used as the answer.  I realize this disables type ahead, but
I can live with that.  Anyone know how to do this?

Thanx,
