Hi,
I'm running a version of Tom Igoe's cat email program.
Basically a sensor is hooked to an Arduino and a Processing program reads the incoming data and sends an email.  Everything works fine on my MAC.  I need to put it on a Dell with XP. I downloaded drivers for XP from here http://www.ftdichip.com/Products/FT232R.htm and it now reads the Arduino fine.
However, when it starts to read actual data it gives me the following error:

Error 0x5 at /home/bob/foo/rxtx-devel/build/../src/termios.c(482): Accejava.io.IOException: No error in nativeavailable

ss is denied.

Anyone know how to fix this?  Is it a driver issue, a java issue or Processing issue?
Thanks.
