On the SCO box I have here with tcsh the same applies to
/etc/csh.cshrc (I just tested this).

You can (on this system at least) get away with calling stty on
non-interactive shells, although it does generate an error so one
probably should not.

Unfortunately on this SCO box (which I did not set up) it was doing
ALL of the things it should not!
