You might want to try libbulldog (http://www.libbulldog.org).
Here's an example: http://libbulldog.org/bulldog/examples/serial-example/ It can do "advanced" Serial communication as well, but has not been tested on Debian. By "advanced" I mean settings things like setting parity, databits and stop bits. Maybe that is sufficient for you. But you'll probably have to tweak the Java side a little, I don't know if the Debian devices match the angstrom serial devices. What I can say about the error, though, is, that you will also get it, when the binary format does not match your system. Am Mittwoch, 30.
