Supplementary explanation

• When all the applications belonging to the communication box acquires the message, a null string is set.
• No <type>onreceive</type> is notified if a communication error occurs.
  To notify the disconnection event, implement the <reconnect>.
• If a communication error occurs and it is deemed that no recovery will take place, notify <disconnect>.
  Since no <type>onreceive</type> is notified, detect data transmission failures in <disconnect>.
