3.3.2 Description
This command is used to set the command line carriage return character S3. S3
saves the command line carriage return character in the form of ASCII code value.
This character is sent by TE. It means the end of a command line, and is identified by
the MS. This character is also sent by MS, and serves as a part of the header, tail and
end mark of the “result code” and “information response”.
When using the “S3=<value>” command to set S3, the current S3 character can serve
as carriage return character of this command line, and the “result code” of this
command line will use the newly set S3 character immediately, rather than waiting
until the next command line.
