This attribute exists only for installed cards that support detecting an interlock break.
Otherwise, the return value will be nil.
If card supports detecting an interlock break, set this attribute to the desired response.
To enable interlock override on the card, set to slot.ON. Otherwise (if an override
performed on card is not desired), set to slot.OFF. This setting applies to all interlocks
on the card.

slot[3].interlock.override = slot.OFF
