Alternate generic way to reset your favorite tty settings: "stty -g"
outputs a string of the current stats that you can't read but stty can.

	$ stty -g
	d26:5:dad:3b:7f:1c:8:15:4:0:0:0

It turns out that it maps directly to |struct termio| fields,
but you don't need to pay attention to the specifics.  Now,
set this string in your .profile after setting your favorite
stty modes:

	STTYMODES=`stty -g` ; export STTYMODES    # save tty modes

Now `oops' (I call it `reset') can be a shell script that does:

	if [ "$STTYMODES" ] ; then
		stty $STTYMODES
	else
		stty sane erase '^h' intr '^c' kill '^y' echoe ixany
	fi
	stty

If you have saved your tty modes, they are restored, otherwise you
get some hopefully reasonable defaults.
