Mark:

I have been wondering if I might be able to create a driver for this device
using the Java interface to ECS.  I know that the Java interface works for
applets.  I am wondering if it works for applications.  Since I need to get
access to the serial port, I think that I would have to create an
application.

What are your thoughts?

Kevin
