There are a few opensource ones that support the javax.comm interfaces on top of the serial io stuff from http://www.rxtx.org/
We've been looking at the SerialIO (http://www.serialio.com) product and have found it to be pretty good so far and fairly inexpensive. As you need to hook in some binary libraries into the JVM for serial support, it's nice to get the source for both the driver and Java classes (which SerialIO) provides in case you run into any issues.

Guys,
This is slightly off-topic, but since there are so many Java experts around
here, I hope someone will react and help me off-list.
For a private pet project I need to connect to a microcontroller using the
serial port. I currently have this running as a Delphi program on a Windows
95 machine, but I want to replace it with an improved version in Java/Cocoon
on a Linux machine.
To keep things simple I want to write a simple program that can read the
serial port and put the info in a text file in a directory and read a text
file from a (other) directory and put it on the serial port.
A Cocoon-based webapp will read the resulting files and generate graphs (in
SVG e.g.) and ask for user input which is written to other files.
The problem is: how do I write the part that can communicate with the serial
port? I don't know if I can do this in Java and I have never written
software specifically for the Linux platform.
Thanks.
Bye, Helma
