[erlang-questions] TCP Flow Control

[Joel Reymont]

{active, once} should do it, e.g after accepting

     inet:setopts(Socket, [{active, once},
                           {packet, 0},
                           binary]),

and then

handle_info({tcp, Socket, Bin}, State)
   when Socket == State#state.socket ->
     inet:setopts(Socket, [{active, once}]),
     {ok, State1} = dispatch(Bin, State),
     {noreply, State1};
