    4.4.1 DDNS (Dynamic Domain Name System) If the CSE-M32 obtains its IP address, it notices to the service provider. Then the service provider serves DNS service. So, even though user doesn’t know the CSE-M32’s IP address, user can connect to the CSE-M32 by the host name (after DNS looking up.) The DDNS service provider that the CSE-M32 supports is only Dyndns (https://dyn.com/dns/) currently.

    Data before TCP connection will be handled based on the [Event Byte] settings. If the [Event Byte] is 0, the data that comes to CSE-M32’s serial port will not be recognized. If it is not 0, the serial data before TCP connection will be temporarily saved to be sent to the host after the connection.
