On this particular box, the QAUTOCFG has always been 1.  I really don't
like that (for just this reason) and changed it to 0.

I don't think that would work in out situation.  The local (to the 400)
router actually emulates a 5494 and creates the devices even if the
remote controller isn't there.  Turning the terminal off has no effect
on this part.

I don't know of any security problem with QAUTOCFG, but if the attacker
has lan access, the QAUTOVRT SYSVAL would apply.  There is no Internet
access to the 400 in question, so someone would have to have physical
access to the LAN.
