*  Bind to a port and listen for incoming connections:
*  This example will listen at port 5555 and allows for a backlog
*  of 25 pending connection requests.

*  Get the next incoming connection
*  Wait a maximum of 20 seconds (20000 millisec)

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

*  Send a "Hello World!" message to the client:

IF (lnSuccess <> 1) THEN
    =MESSAGEBOX(loConnectedSocket.LastErrorText)
    RELEASE loConnectedSocket

*  Close the connection with the client.
