  <p>but i expect one character: F0        ð</p>
  
  <pre class="lang-java prettyprint-override"><code> public void WritingDataToPort() {
          SerialPort port = new SerialPort("COM26");
          try {
              System.out.println(port.openPort());
              port.setParams(9600, 8, 1, 0);
              port.writeString((char)240+""));
              port.closePort();
          } catch (SerialPortException ex) {
              System.out.println(ex);
          }
   }
  </code></pre>
