1.1 Windows 64Bit

rxtx library by default has no Windows 64Bit *.DLL.

But there are people providing these on their own website, like: http://www.cloudhopper.com/opensource/rxtx/

The Install.txt from Cloudhopper says:

For a JDK installation:
Copy RXTXcomm.jar ---> <JAVA_HOME>\jre\lib\ext
Copy rxtxSerial.dll ---> <JAVA_HOME>\jre\bin
Copy rxtxParallel.dll ---> <JAVA_HOME>\jre\bin
