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!
