+            <p>When this option is set to <c>false</c>, as it is by

+              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

+              <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

+              and one which was aborted (intentionally or unintentionally)
+              by the TCP peer. A call to

+              will return <c>{error, econnreset}</c>. In

+              <c>{tcp_error, Socket, econnreset}</c> message
+              before the usual <c>{tcp_closed, Socket}</c>, as is
