serial port

hardware to which you may attach a modem, serial printer or other RS-232C device. Java does not currently officially support such a device. Serial port support arrived with the JDK 1.2 javax.comm.SerialPort. You can read up on how it works in a JavaWorld article or see what Sun has to say about the Java Communications API 2.0. Solutions Consulting has implemented a commercial implementation.

Central Data has created the PortIO interface and an implementation for their EtherLite ® serial/parallel cards. The source code is in the public domain to make it easy to port to other hardware or platforms. Take a look at Trent Jarvi's RXTX which comes free with source code for Linux, Irix, SunOS, and other Unixes. See the essay More Than You Wanted To Know About RS232C 2004-06-28 . EOS overview, Oberon Software, JavaWorld article. At Gamelan, there is a shareware library by Markus Bauer (from Germany) that does serial comm. Kevin Timm and Mark are working on an WIN/OS2/Linux serialport class.

Serialio.com have created the SerialPort package. It handles various platforms including Linux. It lets you also get at virtual ports.

Finally, Sun themselves have created a Java Communication's API which defines a platform-independent way to do serial port communication. You can get it from JavaSoft. Beware, it has compatibilty problems with Java Web Start.
