-  // Mini-tutorial for Connect() :-)
-  // ---------------------------
-  //
-  // There are two ways to use Connect(): blocking and non-blocking,
-  // depending on the value passed as the 'wait' (2nd) parameter.
-  //
-  // Connect(addr, true) will wait until the connection completes,
-  // returning true on success and false on failure. This call blocks
-  // the GUI (this might be changed in future releases to honour the
-  // wxSOCKET_BLOCK flag).
-  //
-  // Connect(addr, false) will issue a nonblocking connection request
-  // and return immediately. If the return value is true, then the
-  // connection has been already successfully established. If it is
-  // false, you must wait for the request to complete, either with
-  // WaitOnConnect() or by watching wxSOCKET_CONNECTION / LOST
-  // events (please read the documentation).
-  //
-  // WaitOnConnect() itself never blocks the GUI (this might change
-  // in the future to honour the wxSOCKET_BLOCK flag). This call will
-  // return false on timeout, or true if the connection request
-  // completes, which in turn might mean:
+  // we connect asynchronously and will get a wxSOCKET_CONNECTION event when
+  // the connection is really established

   //
   //

-  //   a) That the connection was successfully established
-  //   b) That the connection request failed (for example, because
-  //      it was refused by the peer.
-  //
-  // Use IsConnected() to distinguish between these two.
-  //
-  // So, in a brief, you should do one of the following things:
-  //
-  // For blocking Connect:
-  //
-  //   bool success = client->Connect(addr, true);
-  //
-  // For nonblocking Connect:
-  //
-  //   client->Connect(addr, false);
-  //
-  //   bool waitmore = true;
-  //   while (! client->WaitOnConnect(seconds, millis) && waitmore )
-  //   {
-  //     // possibly give some feedback to the user,
-  //     // update waitmore if needed.
-  //   }
-  //   bool success = client->IsConnected();
-  //
-  // And that's all :-)
+  // if you want to make sure that connection is established right here you
+  // could call WaitOnConnect(timeout) instead
