Now I see, i have to often used config when other end was other end of
physical cable ;)
There where sevaral topics about detecting connection break, with
techniques like Keep-Alive Packets mentioned.
TCP/IP itself is capable of delivering packets in connection even when
physical link was down between them, sothere is no simple/ultimate
"other plug out" on this layer.
