You can change the owner of /bin/cu to 'root' and set the permissions to 4555. (This may have serious security repercussions tho'...) This will allow "cu" to run with the UID of the owner (which you set to 'root'). The "real" solution for this problem is being worked through defect support and
final solution will not be available for at least two updates (>3004).
I am not real sure where the default port permissions are set, but I know that
this was changed for a "security enhancement".
