  • "SerialSend" is a really useful little Windows .exe for command line serial connections. By default it just sends your string to the highest COM port. See

  • On my Debian sid Linux system, dedicated FTDI-like adapters show up as /dev/ttyUSB*, and Arduino Uno shows up as /dev/ttyACM*. The following command lists all of them:

    $ ls /dev/ttyUSB* && ls /dev/ttyACM*

  • A good Linux serial terminal option available in most repositories is gtkterm. Run it with:

    $ gtkterm -p <port_name> -s <baud_rate>

    or just launch it and use the menu options to set the device and other configuration.

  • PuTTY could be added to this since that does have Serial support, otherwise a very good Serial primer.

  • Well written, and highly informative. Thank you for saving me a ton of time.

  • Great work! This was quite helpful. Love the OG reference. I have an autographed copy of that ICE-T album...
