  • Data conferencing arrangement for stations having keyboards and displays, using a keyboard buffer and a screen buffer
    Patent number: 4939509
    Abstract: An arrangement for data conferencing either multiple computers (FIG. 1), or multiple terminals with a computer (FIG. 4), includes software (21;511) for communicating keystrokes from conference participants to an application program (22;550) that is the object of the conference, and for communicating display signals from the application program to the participants. In one embodiment (FIG. 1), a first program (23) executing on a first computer (PC 2) transmits first computer-generated keystrokes to a second computer (PC 1), and displays on the first computer images received from the second computer, while a second program (21) co-resident with the application program (22) on the second computer enters received first computer keystrokes into the second computer, and sends second computer-generated images for display to the first computer. In a second embodiment (FIG. 4), a program (511) executing on a UNIX.RTM.
