10.7.2 Interface Description
This command disables a TCP/UDP connection or disables the TCP/UDP function.
If <link_id> is set to 1–5, it indicates that the corresponding established connection is
disconnected. To disconnect a TCP connection, four handshaking operations are
needed for both party. UDP connection can be disconnected directly.
If <link_id> is set to 6, it indicates that the server listening function is disabled for the
module.

which is similar to dial-up disconnection.
