I agree.

Unfortunatley were using a surface mount part, I'm hoping I can
determine if the reset pin has been disabled or if the lock bits are
set...

Thanks for the info, thats what I was afraid of. I'm going to have our
tech lift the reset pin to see if the pullup is still present... Does
anyone know if there is a way to tell if the lock bits are set?
