I'm trying to acccess the serial port using the Java Communications API and I get this error. I followed these instructions to install:
1. Download and unpack the javacomm20-win32.zip file.
2. Place the win32com.dll in <jdk>\jre\bin directory (or the \jre\bin subdirectory f your current J2SDK directory.)
3. Place the comm.jar in <jdk>\jre\lib\ext.
4. Place the javax.comm.properties in <jdk>\jre\lib.
5. Do not alter the CLASSPATH.
I ran this on XP with 1.5.0 and 1.4.2 and both gave the same exception. What can I do to fix this?
