The VideoIO simply executes the commands send. For many applications, the desired behavior is to send a command to the VCR followed by a requestStatus. This class adds state requests to the command observable for requests that need it. Typical usage:

     VideoIO io = new RXTXVideoIO("COM 1");
     StatusDecorator decorator = new StatusDecorator(io.getCommandSubject());
     // That's it! Some commands will automatically trigger a status request.
     io.send(VideoCommands.STOP);
