Abstract: A data processing system having a central or main data processor and a plurality of remote data terminals each having at least one selectively changeable terminal address. The central processor is coupled in a poll-select environment to the various remote terminal processors via a communication link. The respective remote terminals are able to modify the poll-select sequence as set up by the central processor by selectively changing its terminal address for either the poll or select mode. Additionally, groups of the remote terminals may be assigned a selectively changeable group or broadcast address which may be changed either locally at the remote terminal or remotely by the central processor.
