Question: I'm having problems with the JavaComm (javax.comm) serial / parallel A

Question: I'm having problems with the JavaComm (javax.comm) serial / parallel API from Sun ver 2.0 for the Win32 platform. It works with JDK 1.1.8 or lower, but I cannot get it to work with Java2 - 1.2.2 and 1.3. It refuses to see my serial ports...
Answer: JavaComm 2.0 works with all Java 2 distributions including 1.3 and 1.3.1. However there are a few rules:

1. Install JavaComm for each JRE you are using. Often it's difficult to figure out what JRE is in use. It can happen that you use two different versions from command line and form your IDE where you develop your program.

2. Install three files into the places:

in32com.dll --> jre/bin
comm.jar --> jre/lib/ext
javax.comm.properties --> jre/lib

After that it should work!
