APPARATUS FOR MONITORING AND/OR CONTROLLING DG-243 THE OPERATIONS OF A COMPUTER FROM A REMOTE LOCATION ABSTRACT OF THE DISCLOSURE Apparatus for monitoring and/or controlling the operations of a computer at a user site from a support center over a telephone line, the computer at the user site including a central processing unit (CPU) and a display terminal. The apparatus includes a telephone instrument at each location connected to the telephone line, a display terminal connected to an acoustic coupler at the support center and a control and switching device at the user site connected to the CPU, to the display terminal at the user site and to an acoustic coupler. When a link is established between the acoustic coupler at the support center and the acoustic coupler at the user site over the telephone line, the display terminal at the support center is operable with the display terminal at the user site in either an on-line mode or a conversational mode. In the on-line mode, either display terminal can input to the CPU and the output from the CPU is displayed at both display terminals. In the conversational mode, the CPU is disengaged and inputs from either display terminal are displayed at both display terminals. In the absence of the link, the display terminal at the user site is operable with the CPU through the control and switching device. -1-
