    This example shows how to set up an echo TCP/IP server. Start the echo server on port 4000 and create a TCP/IP client object. Connect the TCP/IP client object to the host.

    echotcpip('on',4000)
    t = tcpclient('localhost',4000);
    

    Write to the host and read from the host.

    writeline(t,'echo this string.')
    data = readline(t)
    
    data = 
    
        "echo this string."
    
    

    Stop the echo server, disconnect the TCP/IP client object from the host, and clear the TCP/IP client object.
