Actually, you can dispense with the business of hitting rubout to
terminate a read, by using the mods Marcus figured out and I installed
some months ago.  A card with $$EOF in the first five columns and the
rest blank will be seen as end-of-file on /dev/cr (use /dev/rcr if
you don't want this).  This way, you can do everything in one step:

	dd if=/dev/cr of=foo cbs=80 conv=trim

will get you a normal text file from the cards.  This won't work for
/dev/rcr and the rubout trick, you'll have to use the two-stage method
for that.
