<h3>Installing Java Comm Drivers for Linux</h3>
<ol>
<li>Extract the Solaris version of the comm drivers
(<code>javacomm20-x86.tar.Z</code>) to <code>/java</code>.</li>
<li>Copy <code>comm.jar</code> to
<code>/usr/lib/java/jre/lib/ext/</code>.</li>
<li>Copy <code>javax.comm.properties</code> to
<code>/usr/lib/java/jre/lib</code>. Change the driver line to read
<code>Driver=gnu.io.RXTXCommDriver</code>.</li>
<li>Extract the low-level "RXTX" drivers (<code>rxtx-2.0-4.tgz</code>)
to <code>/java</code>. <u>Make sure you have the version that uses
<code>javax.comm</code> (not <code>gnu.io</code>)</u>. This refers
to the packages that the Javacomm classes appear in, not the
low-level driver referred to in the previous step.</li>
<li>Change directory to <code>/java/rxtx-2.0-4</code> and build the
low-level drivers as root (make sure your system has the standard
build tools installed): make sure <code>JAVA_HOME</code> is set,
then run <code>./configure</code>, <code>make</code>, and <code>make
install</code>.</li>
</ol>
<h3>Installing Java Comm Drivers for Windows</h3>
<ol>
<li>Extract the Windows version of the comm drivers
(<code>javacomm20-win32.zip</code>) to <code>C:\java</code>.</li>
<li>Copy <code>comm.jar</code> to
<code><java-install-dir>/jre/lib/ext/</code>.</li>
<li>Copy <code>javax.comm.properties</code> to
<code><java-install-dir>/jre/lib</code>.</li>
<li>Copy the low-level driver (<code>win32com.dll</code>) to
<code><java-install-dir>/bin</code>.
</ol>
<p>Because of the locations these files are installed to, there is no
need to add the drivers to your classpath.

Just FYI. If you set $JAVA_HOME and extract the CommAPI from Sun, The
configure script will place comm.jar and the javax.comm.properties file
in the correct locations and put the correct text in the properties file.
Either method is fine.
The CommAPI documentation from Sun was intended for JRE/JDK 1.1. There
was no ext directory at that time. This often causes confusion with new
java users.
