Java SE (Java Platform, Standard Edition)

Hello, I was trying the latest version of javax.comm in Linux (this is the first release for this OS). But I get this IOException when I open /dev/ttyS0 in SerialDemo (as root):

I'm running Debian Testing, linux kernel version 2.6.12-1-686, JDK 1.5.0_04 and running 1.4.2_07 I also get this error.

Maybe I should post this as a bug, but I wanted some feedback from you first.

Thanks!
