The”Local TCP port” is the TCP port that NPort IA5150/5250 uses to listen to connections, and 
that other devices must use to contact NPort IA5150/5250. To avoid conflicts with well known

Optional 
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 IA5150/5250 
so that the user does not need to configure the program.
