[2.0] "LIST\r\n" Not retrieving ftp directory?

[high6]

I send TCP packets to login to an ftp server and everything works but "LIST\r\n" doesn't return anything not even an error.

What I am trying to do is have an rss type feed of these files.

ftp://64.151.85.204/zf/

here is the code I am trying.

            tcp.Connect("64.151.85.204", 21);
            tcp.Client.Send(Str2Buf("USER anonymous\r\n"));
            tcp.Client.Send(Str2Buf("PASV\r\n"));
            tcp.Client.Send(Str2Buf("CWD /zf/\r\n"));
            tcp.Client.Send(Str2Buf("NLST */*\r\n"));

Here is what I received.



(I know there is an ftp class but it is easier to work with tcp packets for me)
