#  The string "localhost" is for testing on a single computer.
#  It would typically be replaced with an IP hostname, such

#  Set maximum timeouts for reading an writing (in millisec)

#  The server (in this example) is going to send a "Hello World!"
#  message.  Read it:

    print socket.lastErrorText() + "\n"
    exit
end

#  Close the connection with the server
#  Wait a max of 20 seconds (20000 millsec)
socket.Close(20000)
