I'm trying to write an Imap4 client.
For that I use a SslStream to Connect to the Server.
Everything's fine until I send the "Login" command.
When I try to get an Answer to it, SslStream.ReadByte() block the thread.
The result is that my programm crashes always.
Whats happening here??

Code:

 if (ssl)
{
     s = stream;
}


        int cc = 0;
        MessageBox.Show("entered");
        while (true)
        {
            int xs = s.ReadByte();
            MessageBox.Show(xs.ToString());
            if (xs > 0)
            {
                buf.Add((byte)xs);
                cc++;

                if (xs == '\n')
                {
                    break;
                }
                if (cc > 10)
                    MessageBox.Show(en.GetString(buf.ToArray()));
            }
            else
            {
                break;
            }
        }
        MessageBox.Show("left");
