title: Serial communication API for Java on 64 bit systems (modem interaction)
body: <p>I'm searching for an serial communication API for Java. Very important is the support of 64 bit systems. I've used rxtx with the 64 bit libs of <a href="http://www.cloudhopper.com/opensource/rxtx/">Cloudhopper</a> but on some Windows Server 2008 systems I got heavy problems with jvm crashes when accessing (virtual) serial ports.</p>
  
  <p>The main purpose is interacting with analogue modems, maybe there is another way of modem communication in Java?</p>
  
  <p>It would be very nice if the API is free of charge.</p>
