My understanding is that 31 is illegal as a device address, used to 
untalk/unlisten all devices. Perhaps what you mention is something from 
early HPIB (as opposed to newer GPIB/IEEE-488).

There are non-HP talk-only devices, but they would use a normal 0-30 
device address.

But, I could be wrong, I don't pretend to be an expert on 488.
