1. A method for performing input/output between an application executing on a computer system and a graphics display terminal connected to the computer system by a local area network, comprising the steps of:

  • executing the application on a central processor;

    within the application, generating output which is not in a form capable of driving a graphics terminal;

    when output is generated by the application, communicating such output to a separate display controller processor within the computer system over a computer system bus;

    on said display controller processor, executing graphics display routines for translating generated output into a form capable of driving a graphics terminal;

    communicating translated output from the display controller processor to a graphics terminal, over the local area network, for display;

    when input is generated at the graphics terminal, communicating the generated input to the display controller processor over the local area network;

    on the display controller processor, translating generated input to a form capable of communication to the application; and

    communicating the translated input to the central processor, over the computer system bus, for use by the application.
