Hi,
I've written the version 0.2 of "Arduino TTY".
You can now save the bytes as textfile, as binary file and as Xml file.
I added a notify-icon, a preferences and about dialog.
"Arduino TTY v0.2" runs on Windows XP/Vista/7, Mac OS X 10.5/10.6/10.7, Ubuntu Linux 11.10 and on other linux based systems.
You can download this application on the project-homepage:
http://code.google.com/p/arduinotty/
In the next version I'll fix a known bug (sometimes when you're connected and you quit the application, it doesn't quit),
as well I want that this applications integrates better on Windows, Linux and Mac OS X.
