Must be 2.• Port : Specify a local port number, or set to 0 (the local portnumber will be chosen by the Ethernet subsystem). For TCPclient operations, specify 0 unless you want a specific local portnumber. For TCP server communications, specify the portnumber on which to accept incoming connection requests. ForUDP, to receive datagrams on a specific port, you must specify alocal port number.• Addr : Specify an IP address.
