ABSTRACT:
A data processing network having a host computer, a plurality of terminals, a cable for transmitting data between the host computer and the terminals, and a controller for controlling character data sent from the host computer to the terminals and keystroke data sent from the terminals to the host computer. Data is transmitted in a cycle of time frames, with each time frame having a plurality of time slots, one time slot being allocated to the transmission of one character from the host computer to a designated terminal. Further, each time frame includes a time slot for the transmission of a keystroke from a designated terminal to the host computer. The terminal which may transmit a keystroke to the host computer is designated in a syn/poll character generated at the beginning of each time frame by the controller.
