Cross Platform Serial port communication in Java?

Question

I'm trying to do serial communication with Java. It's hard to believe that there's not some nice, out of the box solution like there is in C#.

I'm looking around the SerialIO website, but it's not clear that there's a free .jar I can download to get the functionality I need. (Is it just for sale? I can't find a link for a .jar download of any sort.)

All I need is read/write over a serial port, and setting a baud rate. Nothing fancier than that.

Edit: I require that it works on 64 bit Windows and Mac OS X. The Java Communications API only has implementations for Linux.

Answer 1

Maybe RxTx java library is what you are looking for http://rxtx.qbang.org/wiki/index.php/Main_Page

Answer 2

SerialIO is a commercial product.

Take a look at Java simple serial connector

jSSC-0.9.0 Released and available for download. jSSC (Java Simple Serial Connector) - library for work with serial port from Java. jSSC >support Win32 (Win98-Win7), Win64, Linux(x86, x86-64), Solaris(x86, x86-64), Mac OS X 10.5 >and higher(x86, x86-64, PPC, PPC64).

It is licensed under LGPL. We have been succesfully using it in production for over half a year now. It has shown to be stable, as opposed to RXTXcomm.
