I've written a serial terminal in C-Sharp for the Arduino plattform.
The advantage against the serial terminal from the "Arduino IDE" is,
that you can receive and transmit the bytes not only in text (ASCII).
You can receive and transmit the bytes as binary, octal, decimal
and hexadecimal values too.
Also you can save and open the received and transmitted bytes.
You can download this application on the project-homepage:http://code.google.com/p/arduinotty/
This application works on Windows XP / Vista / 7 and on Linux based systems.
Please test this application, because I could it test it only on my PC.
Also it would be nice, if you can give some feedback to these questions:
1. Does it work on your system?
2. Is it easy to use?
3. What do you like to see in the next release of "Arduino TTY"?
4. Looks the icon ok, or does I need a new one?
5. What do you don't like?
Thank you for your attention!
