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

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�504) receives keystrokes from connected terminals (501-503) and sends them to the application program (550), and receives images from the application program and transmits them to the terminals.

An arrangement for interactively coupling a first and a second station each having a keyboard and a display, the second station further having a screen buffer for storing display signals that represent images displayed by the display of the second station and a keyboard buffer for storing keystroke signals generated by the keyboard of the second station, which stations are interconnected by a signal transmission path, the arrangement comprising: first control means resident at the first station for transmitting keystroke signals generated at the first station\s keyboard to the second station, and responsive to display signals received from the second station for displaying an image represented by the received display signals on the first station\s display; and second control means resident at the second station responsive to keystroke signals received from the first control means for storing the received keystroke signals in the keyboard buffer of the second station as keystroke signals received from the second station\s keyboard, and responsive to the second station storing in the screen buffer of the second station signals representing an image for display by the second station\s display, for transmitting display signals representing the image to the first control means.
