Displaying windowing application programs on a terminal

摘要

A video display terminal operating with a graphical user interface which provides windowing functionality to permit use of popular application programs resident on a server, without requiring more than application data to be transmitted from the server, and keyboard and mouse information to be transmitted from the terminal to the server. The terminal includes processing means adapted to receive windowing information supplied by programs executing on a remotely located application server. The terminal also includes a display for the windowing information supplied by programs executing on the remotely located application server. The present invention further provides for simultaneously maintaining more than one connection between the terminal and server and establishing more than one virtual machine on the terminal with each virtual machine running an open session.
