sent over the Erlang binary protocol.

f.send!(:result, "You said: #text")
f.receive_loop
end
end

== USAGE (Erlang side):

-module(echo).
-export([test/0]).

test() ->
Cmd = "ruby echo.rb",
Port = open_port(Cmd, [4, use_stdio, exit_status, binary]),
Payload = term_to_binary(<<"hello world!">>),
port_command(Port, Payload),
receive
{data, Data} ->
Text = binary_to_term(Data),
io:format("~p~n", [Text])
