code: private static String getShortString(IoBufferEx buffer)
      {
          int len = buffer.getUnsigned();       
          StringBuilder builder = new StringBuilder();
          for (int i = 0; i < len; i++)
          {
              builder.append((char)(buffer.getUnsigned()));
          }
          String s = builder.toString();
          return s;
      }
