Abstract
In a data processing network using time slot protocol to transmit characters from a host computer to a plurality of users and to transmit a keystroke from a specified user back to the host computer, a terminal device for generating a first link flow control command in a designated time slot for stopping the transmission of characters which are being transmitted from the host computer to the terminal device at a rate faster than the rate at which they are first being outputted by the terminal device. The terminal device generates the link flow control command responsive to storing a first set number of characters received from the host computer. The terminal device further generates a second link flow control command for restarting the transmission to it of characters after it has outputted sufficient characters such that a number of characters less than or equal to a second set number is stored.
