 You can complete this Learning Path on Windows, macOS, and Linux host computers.
 
 ### Windows
 
-Install [PuTTY](https://www.putty.org/index.html), which provides a lightweight serial terminal for UART communication.
-
-After installation:
-
-1. Connect the development board over USB.
-2. Open **Device Manager** and locate the board's COM port under **Ports (COM & LPT)**.
-3. Open PuTTY and configure:
-
-   - **Connection type**: `Serial`
-   - **Serial line**: your board's COM port (for example `COM5`)
-   - **Speed**: `115200`
-
-4. Select **Open** to connect to the Zephyr UART shell.

 ### macOS
 
-macOS includes a built-in UART terminal utility through the `screen` command, so no additional software is required.
-
-After connecting the development board over USB:
-
-1. Open a terminal window.
-2. List available serial devices:
-
-   ```bash
-   ls /dev/tty.*
-   ```
-3. Connect to the UART shell with:
-
-   ```bash
-   screen /dev/tty.usbmodemXXXX 115200
-   ```
-
-Replace `/dev/tty.usbmodemXXXX` with the serial device shown on your system.
-
-To exit `screen`, press the `Ctrl` key and `A`, then `K`, then `Y` to confirm.

-3. If you see a permission error when connecting, add your user to the `dialout` group and log out and back in:
-
-   ```bash
-   sudo usermod -aG dialout $USER
-   ```
-4. Connect to the UART shell with:
-
-   ```bash
-   screen /dev/ttyACM0 115200
-   ```
-
-Replace `/dev/ttyACM0` with the device shown on your system. Boards using a CP210x or FTDI USB-UART chip typically appear as `/dev/ttyUSB0`.

 Workbench for Zephyr supports multiple debug runners depending on the connected board. The FRDM-MCXN947 board uses the onboard CMSIS-DAP/LinkServer interface for flashing and debugging, and UART over USB for shell access.
