Well, this means, that you have such a shell, that has a ``second''
initialisation file.  (Eg: csh has .cshrc, sh/ksh has the file named in the
ENV variable, bash has Idontknowthename, etc.)  In that file, you have an
stty command.  You have to ``ifdef'' the stty command, like this:
sh/ksh/bash:
if "$-" in
	*i*)	# it is an interactive shell
	stty ...
	any command, which hasn't any meaning in non-interactive shells
	;;
	*)	# it is a non-interactive shell
	any command, which has any meaning in non-interactive shells
	;;
esac

csh/tcsh:
if ( $?prompt ) then
	# interactive shell
	stty ...
	any command, which hasn't any meaning in non-interactive shells
else
	# non interactive shell
	any command, which has any meaning in non-interactive shells
endif

That's it.
