title: Connecting to Biometrics Fingerprint Machine via Java Sockets
body: <p>So I am trying to create this application where I can retrieve the data from different types of biometric fingerprint devices. Most, if not all of them, I think, does not have SDKs. A stand-alone app (the same as what I am trying to achieve) was provided together with these devices and I can connect to them via TCP/IP (<code>192.168.1.201:4370</code>). However, if I try to access it via sockets in Java, it refuses to connect. </p>
  
  <p>Code:</p>
  
  <pre><code>    Socket socket = new Socket("192.168.1.201", 4370);
      BufferedReader in = new BufferedReader(new InputStreamReader(socket.getInputStream()));
  
      String line;
      while (true){
          line = in.readLine();
          if (line != null){
              System.out.println(line);
          }
      }
  </code></pre>
  
  <p>Where do you think should I go from here?</p>
  
  <p>Thanks!</p>
