3) Parameters
Local port
This is the TCP port number through which remote host can connect a TCP session, and, send
and receive data. Incoming connection request to the ports other than Local Port will be rejected.
The LS110 does not restrict the number to a specific range, but it is strongly recommended not to
use the well-known ports for certain application (See Appendix B: Well-known Port Numbers). To
change the port number, refer to next example.
