   No, the serving side would not need to cooperate. If the receiving end   
   senses incoming data after a certain threshold, it could very well sound   
   an audible alarm signalling that fact without help from the sending end.   
   Afair I have never looked into the telnet sources, but one could eg   
   record the time of incoming data and if the difference between two   
   events exceeds the threshold, an audible alert could be raised.
