[erlang-questions] Flash client communication with Erlang Server problem

This is an erlang problem, it seems. I have this code to test the client
sending data, written in Actionscript 3:
Code:var socket:Socket=new Socket("localhost", 2345);
socket.addEventListener(Event.CONNECT, connected);
private function connected(event:Event):void {
socket.writeInt(12); //packet length, should be correct? 4 bytes each?
socket.writeInt(3);
socket.writeInt(6);
socket.writeInt(9);
socket.flush();
}
Then I have this small server, written in Erlang:
Code:start_nano_server() ->
{ok, Listen} = gen_tcp:listen(2345, [binary, {packet, 0},
{reuseaddr, true},
{active, true},
{packet_size, 128}]),
{ok, Socket} = gen_tcp:accept(Listen),
gen_tcp:close(Listen),
receive_data(Socket, []).
receive_data(Socket, SoFar) ->
receive
{tcp,Socket,Bin} ->
receive_data(Socket, [Bin|SoFar]);
{tcp_closed,Socket} ->
Bytes=list_to_binary(reverse(SoFar)),
io:format("~p~n",[Bytes])
end.
Now, no matter what I send from the client, I ALWAYS get
[<<0,0,0,4,0,0,0,32>>] as the response. I can try writing bytes to the
socket directly instead of ints, and I get the same thing. I can write more
or less data, same result. UTF strings same result. Even when specifying "4"
as the packet header length, I just get the same consistant result of
[<<0,0,0,32>>] instead. I don't understand what I'm doing wrong here.
