        // Do something else
      }
      // Socket channel is now ready to use
    } catch (IOException e) {
    }

    SocketChannel sChannel = SocketChannel.open();
    sChannel.configureBlocking(false);

    // Send a connection request to the server; this method is non-blocking
    sChannel.connect(new InetSocketAddress(hostName, port));
    return sChannel;
