title: TorCtl connection refused error
body: <p>While browsing about changing identity with tor I have the following script:</p>
  
  <pre><code>from TorCtl import TorCtl
  
  conn = TorCtl.connect(controlAddr="127.0.0.1", controlPort=9051, passphrase="123")
  
  TorCtl.Connection.send_signal(conn, "NEWNYM")
  </code></pre>
  
  <p>But I get this error:</p>
  
  <pre><code>Connection refused. Is the ControlPort enabled?
  Traceback (most recent call last):
    File "python_tor.py", line 18, in &lt;module&gt;
      TorCtl.Connection.send_signal(conn, "NEWNYM")
  TypeError: unbound method send_signal() must be called with Connection instance as first argument (got NoneType instance instead)
  </code></pre>
  
  <p>And What shoul be the passphrase? I have tried without passphrase the same error occurs.</p>
