confi rmation format
Send commands as if operate the buttons on the operation panel. As a general rule, do not send commands continuously,
but send the next command after checking that the present command has been executed and completed. After sending
a command, the command execution result, error type, and command name can be checked by the status returned from
the recorder. To check the actual execution, view the output screen of the recorder on the monitor screen.
Example) Playing back the recorded data in still frame playback.
