    Create a TCP/IP client to connect to your server object using tcpclient. You must specify the same port number you use to create server.

    client = tcpclient("localhost",4000);

    Write some data to the client and view the number of bytes available to be read in the server input buffer.

    write(client,1:5,"uint8")
server.NumBytesAvailable
    ans = 5

    Flush both the input and output buffers of the server.

    flush(server)

    View the number of bytes available to be read.

    server.NumBytesAvailable
    ans = 0

    The input buffer has no data.
