To ensure that we do not keep any 3270 sockets where the client is not connected anymore, we send a packet with the timing mark option after ten minutes of client inactivity. If the client does not answer it, then the socket will be closed automatically. This helps to ensure that there is no half-open situation on the 3270 socket.
