ABSTRACT:
The present invention describes an integrated text and data processing system allowing processing of link data before output. The system also provides simultaneous dual emulation of a display and printer normally associated with a host data processor. In accordance with the first aspect of the invention, an input/output terminal includes a support logic circuit for interconnecting the input/output terminal to a port of an intermediate control unit attached to a central processing unit. The input/output terminal includes separate link and display buffers whereas link data may be stored in the link buffer for processing before output to the display associated with a text processor. In accordance with another aspect of the invention, the input/output terminal may include a plurality of support logic circuits each connected to one of the ports of one or more control units associated with one or more central processing units. This structure allows the text processor in the input/output terminal to simultaneously yet independently emulate a display and printer normally associated with a host central processing unit.
