A receiver unit is added to a Personal Computer (PC) between the existing keyboard output and the PC keyboard input port. The receiver unit is responsive to a hand-held keypad transmitting infrared or ultrasonic signals which are passed to the PC. Also keystroke signals for the keyboard are transmitted via the unit to the PC. As the receiver unit is added by plugging in, no change is required to the PC itself or to its keyboard. A method is described to input a remote keypad to existing designs of the Personal Computer and main-frame terminals. By plugging the existing keyboard into the receiver unit and then the receiver unit into the keyboard socket, as shown in the figure, a very useful design has been implemented.
