This article describes a radio link controller which implements a serial bidirectional communications protocol so that a host computer can be used to control an AM-FM radio. The radio link controller disclosed herein implements a full duplex 1K baud serial link protocol. It enables a personal computer (PC) to use a set of send/receive buffers to communicate with a remote AM-FM radio and to control various performance parameters. A block diagram of the controller is shown in Fig. 1. The send/receive buffers and the timer are part of an adapter that is an interface between the PC and the link controller. The primary elements of the radio link controller are the idle controller, the command executor, and the timer interrupt handler.
