#
# A function that works as a front end for both stty and the `bind'
# builtin, so the tty driver and readline see the same changes
#
#
# Convert between the stty ^H control character form and the readline \C-H
# form
#
cvt()

echo "$@" | cat -v | sed 's/\^/\\C-/'

#
# stty front-end. Parses the argument list and creates two command strings,
# one for stty, another for bind.
