title: possible to import javax.comm on Android? want to open serial device
body: <p>I have a rooted Android device with a USB serial device connected.  The device shows up as "/dev/ttyUSB5"</p>
  
  <p>I would like to open the serial port and read/write from it.  First and foremost... within Android, will it even allow me to read/open /dev/ttyUSB5?  Or within the application will I be prohibited from touching /dev ?  If I cannot touch anything in /dev, then this is all irrelevant.</p>
  
  <p>However, if I can, then I am wondering if it is possible to import javax.comm so that I can communicate with the serial device.</p>
  
  <p>As of right now, I am able to get around this by spawning a native C application which opens the serial port, then I use a socket to read/write to the serial port in Java.  However, it would be much better to do it all in Java.</p>
