Hello, Erlang team!
I try to send magic pack of wake on lan feature (
http://en.wikipedia.org/wiki/Wake_on_lan) in erlang.

code below:
> {ok,S} = gen_udp:open(2025).
{ok,#Port<0.275>}
> gen_udp:send(S, Pack).
{error,einval}
> gen_udp:close(S).

Pack is the magic packet.
i.e. I have an error in gen_udp:send(S, Pack). Please, help me.

PS: sorry for my english, I'm from Russia =)
