Abstract
A state information communications system includes a bus and first and second terminal units of TV set and VCR connected to the bus. The first terminal unit includes control command generator for generating a control command, an information request command generator for generating an information request command, a first communications control for sending the control command and the information request command to the bus, and for receiving information data directed to the first terminal unit. The second terminal unit includes a second communications control for receiving control command and the information request command from the bus, a terminal device having tape deck which operates in response to the control command, a state code generator for generating a fixed state code when the tape deck is in a fixed state and a transient state code when tape deck is in a transient state changing from one fixed state to another fixed state. The first terminal unit is informed, when the second terminal unit produces the transient state code in reply to the information request command, that the second terminal unit is in a transient state for carrying out a state change from a previous state to a state required by the control command.
