The “Command port” is a listen TCP port for IP-Serial Lib commands from the host. In order to
prevent a TCP port conflict with other applications, the user can set the Command port to another
port if needed. IP-Serial Lib will automatically check the Command Port on NPort W2004 so that
the user does not need to configure the program.
