[title] Connect to Duet - Linux
[* blackicon_caution] This step is for '''Linux''' users only! See Step 2 to check the Duet is connected and the Serial Port name. Windows and Mac OS users skip this step.
[* blackblue] Most likely, the first thing you will need to do on a Linux installation is to add the user to the 'dialout' group, to allow permission to connect to the Duet. Do this by opening a Terminal window and sending '''sudo adduser [your_username] dialout'''. Following this, you will need to log out and back in, or possibly restart, to enable this.
[* black] Next, check that the Duet is showing up as connected. Open a Terminal window and send '''lsusb''', which should show an entry for the Duet, then '''ls /dev/tty*''', which amongst the list should show an entry ending 'ACM[number]'. This is the port the Duet is using.
[* blackblue] There are many options to connect using Linux. Our favourite is to use CuteCom, which is a GUI serial terminal. It's available in most package repositories, or install with '''sudo apt install cutecom'''. It should automatically detect the correct port (usually /dev/ttyACM0), and is configured correctly out of the box. Click 'Open' to connect.
[* blackblue] Alternatively, you can use a text-based serial terminal application such as Minicom. Install with '''sudo apt install minicom'''minicom''', and run from a Terminal window with '''minicom -s''', which starts it in setup mode.

[* black] (Instructions to come)
[* blackblue] Finally, you can use the built-in 'screen' terminal. However, you cannot see the commands you type in, and the responses from the Duet are not formatted nicely on the screen. If you want to use 'screen', do this:
[* black] Run '''screen /dev/ttyACM0 115200'''. (Replace "ttyACM0" with the port name if it's different.). You should see a blank screen. Ifscreen, but see note on Duet 2 WiFi below.
[* icon_note] No matter which connection method you use, if you are connecting for the first time to a Duet'''Duet 2 WiFiWiFi''', you willmay see lots of "WiFi''"WiFi reported error: no known networks found"found"'' messages. Don't worry, that's normal. Press returnnormal, and you should get 'ok'.it means that the Duet is working!
