Abstract

This invention solves the problem of supporting two logical display sessions on one physical display station with no modifications to either the host computer (hardware or software) or the display station. A popular and useful function to provide computer users that require access to more than one system is the ability to support more than one logical display session on a single display station. This has been especially popular on personal computers, providing access to the local operating system and programs and to a host computer and its programs. With the advent of the three-tier computer system architecture, an intermediate or departmental system enters the picture. This computer may have attached to it either dependent or intelligent work stations.
