This command sets the command line termination character S3. S3 saves the command line termination character in the ASCII code format.

The character is also sent by the MT to compose the headers, tails, and end flags of the result code and response information.

When running S3=<value> to set S3, use the current S3 as the termination character. The new S3 will be immediately returned with the result code.
