 Important note:
 
-In order to compile and run this plugin, comm has to be installed into 
-the java installation. Once comm.jar is installed in your JRE, you'll
-need to quit and re-start Eclipse PDE in order to recompute the classpath.
+In order to compile and run this plugin, RXTX has to be installed into 
+the jvm. Once RXTXcomm.jar is installed in your JRE, you'll need to 
+quit and re-start Eclipse PDE in order to recompute the classpath.
 
-Linux or Solaris:
------------------
-* Get comm3.0_u1 or later from Sun at 
-  http://www.sun.com/download/products.xml?id=43208d3d
-* Follow the installation instructions. As per 3.0_u1 on Linux, you need to
-  - cp jar/comm.jar $JRE/lib/ext
-  - cp doc/javax.comm.properties $JRE/lib
-  - cp lib/*.so $JRE/lib/i386
-
-Windows:
---------
-* Get comm.jar 2.0.3 ZIP archive from Sun at
-  http://www.sun.com/download/products.xml?id=43208d3d
-  - Extract comm.jar into %JRE%\lib\ext
-* Get rxtx-2.0-7pre1-i386-pc-mingw32.zip from
+Installation:
+-------------
+* Get RXTX binaries from
+  ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7-bins-r2.zip
+* Copy RXTXcomm.jar into $JRE/lib/ext
+* Copy the native libs for your Platform (*.so, *.jnilib, *.dll)
+  into the respective native lib folder of your RSE 
+* More installation instructions are at
+  http://rxtx.qbang.org/wiki/index.php/Main_Page
+* More downloads for other platforms (currently about 30)
+  are available from the "ToyBox" link on
   http://users.frii.com/jarvi/rxtx/download.html
-  - Extract RXTXcomm.jar into %JRE%\lib\ext
-  - Extract rxtx*.dll into %JRE%\bin
-* Create new text file 
-	%JRE%\lib\javax.comm.properties
-  with the following line as contents:
-	driver=gnu.io.RXTXCommDriver
 
-Other platforms (MaxOS X etc):
-------------------------------
-* Get comm.jar 2.0.3 as explained for Windows
-* Get rxtx-2.0-7pre1.tar.gz sources for your platform from
-  http://users.frii.com/jarvi/rxtx/download.html
-* Follow instructions to compile and install. You'll need a 
-  javax.comm.properties file as explained for Windows.
