While it's true that any current machine which can report the keyswitch
position has a secure mode which ignores breaks, it's worth noting
that there are sun systems with keylocks that don't offer this
functionality - the E220R would bean example. It should also be noted
that kbd -a will control this functionality on 'most systems'
according to the man page.

These are dependent on the particular terminal concentrator/console
server you are using - for instance, we use a Lightwave unit which
does not drop attached servers to the OBP when it's power cycled, and
uses a different command sequence to send a break to an attached
device. The bottom line is each device is different, and without the
precise make and model, all one can effectively do is refer the poster
to the documentation for their device.
