This example shows how to set up an echo TCP/IP server.

Start the echo server on port 4000 and create a TCPIP object. Connect the TCP/IP 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 object from the host and clear the TCPIP object.

echotcpip('off')
clear t
