A virtual display driver that can be dynamically loaded and unloaded for remote control of a host computing system. The host computing system includes an original display driver that updates an output display of the computing system based on display commands. A remote control executive executes in kernel-mode within an operating environment provided by the computing system and dynamically loads and unloads the virtual display driver as requested by a user. The remote control executive inserts hooks within the functions provided by the original display driver to trap the display commands received by the original display driver and direct the commands to the virtual display driver for communication to a remote client computer.

Disclosed herein are a system and method for using a remote terminal to control processes executing on a client terminal by transmitting data to the client terminal emulating keystroke inputs at the client terminal. A remote control application program executing at the remote terminal initiates the transmission of a message for emulating keystroke inputs to the client terminal. The remote terminal also executes an operating system having logic for responding to a detection of any one combination of keystrokes of a set of predetermined combinations of keystrokes, independently of any application program executing on the remote terminal. While the remote control application is active, the remote terminal inhibits the operating system from responding to detected keystrokes and transmits a message to the client terminal emulating an input of the detected keystrokes at the client terminal.

A method of sharing glyphs between a source computer and a destination computer having graphical user interfaces includes the step of receiving a first request to display a specified glyph at a first position of a source computer display. A glyph bitmap is created from the specified glyph if an identical glyph was not previously sent to the destination computer. The glyph bitmap is sent to the destination computer. The first request is also sent to the destination computer. The destination computer stores the received glyph bitmap. The first request received by the destination computer is replaced by a second request. In response to the second request, the second computer copies the glyph bitmap to the first position on a destination computer display.
