Setting up a Serial Terminal with Mac* OS X*


You have assembled your Arduino* expansion board or your mini breakout expansion board, installed the appropriate drivers, and flashed the OS image (formerly called firmware).

Steps to Set Up a Serial Terminal

  1. Launch Spotlight by pressing Cmd + Space.
  2. Type terminal.
  3. Select the Terminal app.
  4. In the Terminal window, enter the command:

    ls /dev/cu.usbserial-*

  5. In the list of connected devices, look for a device that contains cu.usbserial. In the example above, the device name is /dev/cu.usbserial-A402YSYU.
    Note: If your device is not in the list, verify that your board is powered on and connected to your system. Select the appropriate link below:
  6. Connect to the USB serial device using the Terminal screen utility by entering the command:

    screen /dev/xx.usbserial-XXXXXXXX 115200 –L

    where /dev/xx.usbserial-XXXXXXXX is replaced by your device unique name. Using the example above, the command would be:

    screen -L /dev/cu.usbserial-A402YSYU 115200 –L

    Note: Adding –L to the command, as shown above, turns on output logging so you can see the results of your commands. To end a session in Screen type Ctrl + A and then Ctrl + K to kill the session. You will be prompted to end the session.
  7. At the blank screen, press Enter twice. A login screen is displayed. 


  8. At the login prompt, type root and press Enter.
  9. Press Enter when prompted for a password. The following screen is displayed: 

    You have now established a serial communication with your board. You can interact with your board by entering common Linux commands. For a summary of useful commands, see Common commands for the Intel® Edison board.
