Announcement of "Arduino TTY". It's a self-written serial terminal for Arduino.


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:

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!

What is the max baud-rate it supports?

The range is from 300 to 115200.

The arduino can easily send at 230400 and 345600 baud (500K worked for me too). Supporting those speeds would give your app an advantage.

Can you set the font?

Many application provide semi-formatted data that needs a mono-spaced font so the characters line up.



thanks for your replies. I'm now coding the next version "Arduino TTY v0.2", and I'll add your improvements:

  1. Higher Baudrate (300 - 500000).
  2. Font selections.

I hope I can deliver it in the next or next two weeks.

But if you have another ideas, please post it.

  • log incoming data to a logfile
  • reverse engineer a few serial terminals and you know your todo-list :slight_smile:


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:

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.


Downloaded the OSX 10.7.5 version and it does not launch after install.
I get the following error in Console:
