+ <p>When this option is set to <c>false</c>, as it is by
+ default, an RST that is received from the TCP peer is treated
+ as a normal close (as though a FIN was sent). A caller
+ to <seealso marker="gen_tcp#recv/2">gen_tcp:recv/2</seealso>
+ will get <c>{error, closed}</c>. In active
+ mode the controlling process will receive a
+ <c>{tcp_close, Socket}</c> message, indicating that the
+ peer has closed the connection.</p>
+ <p>Setting this option to <c>true</c> will allow you to
+ distinguish between a connection that was closed normally,
+ and one which was aborted (intentionally or unintentionally)
+ by the TCP peer. A call to
+ <seealso marker="gen_tcp#recv/2">gen_tcp:recv/2</seealso>
+ will return <c>{error, econnreset}</c>. In
+ active mode, the controlling process will receive a
+ <c>{tcp_error, Socket, econnreset}</c> message
+ before the usual <c>{tcp_closed, Socket}</c>, as is
+ the case for any other socket error.</p>
+ <p>A connected socket returned from
+ <seealso marker="gen_tcp#accept/1">gen_tcp:accept/1</seealso>
+ will inherit the <c>show_econnreset</c> setting from the
+ listening socket.</p>
