Abstract: A communications terminal control circuit is described which includes a preprogrammed memory. The memory provides a plurality of sequential instruction signals each serving to direct at least a selected operational sequence of the terminal. Two command and two status decoders are included, each responsive to at least one of the instructional signals and capable of initiating a unique terminal operation in response to a selected instructional signal from the memory. Means are provided for comparing outgoing and incoming coded information with selected memory locations thereby analyzing such coded information and directing selected operative terminal instructions in response thereto.
