Fair enough - I was thinking of the (clearly redundant) BSD "script".
Here is what you want from standard UNIX tools. Let "dialog.cu" be a
shell script to do your thing. It "read"s from cu and "echo"s to it,
and after doing its job lets you continue by doing

	cat -u < $TTY &
	exec cat -u > $TTY

Start your session like this:

	TTY=`tty`
	export TTY
	mknod tocu p
	mknod fromcu p
	dialog.cu <fromcu >tocu &
	cu <tocu >fromcu

You can be more elaborate and check the fifos first and remove them
afterward etc., but I think the above should be enough to get you
started.
