Java(TM) Communications application programming interface (API) gives Java applications a platform-independent way of performing serial and parallel port communications for technologies such as voice mail, fax, and smartcards. After writing serial or parallel port communications for your application, you can then include those files with your application. Use Java Communications API if you want to write Java programs that access serial or parallel ports.
The Java Communications API supports Electronic Industries Association (EIA)-232 (RS232) serial ports and Institute of Electrical and Electronics Engineers (IEEE) 1284 parallel ports and is supported on systems with the IBM(R) Runtime Environment for Windows, Java 2 Technology Edition, version 1.4.2.
The Java Communications API is supported on the following products:
Using Java Communications API, you can:
To install the Java Communications API:
For example, if you accepted the default directory when you installed the Runtime Environment, the comm.jar file is in the C:\Program Files\IBM\Java142\jre\lib\ext directory.
If you unzip the file in another directory, the files are placed in the same directory structure, but C:\Program Files\IBM\Java142\ is replaced by the directory where you unzipped the file.
If you plan to redistribute Java Communications API with the IBM 32-bit SDK for Windows and your product, you must package the files listed in Installing Java Communications API.The files must be included as part of your product installation and placed in the appropriate subdirectories on the user's system.
To uninstall Java Communications API, delete the following files from the directory where you installed the Runtime Environment:
By default, the Runtime Environment is installed in the C:\Program Files\IBM\Java142\ directory.
You can find API documentation and samples for Java Communications API at the Sun Web site: http://java.sun.com.
