??? example "Access to PiKVM via serial" ??? example "Access to PiKVM via serial console"
Serial is sometimes needed to recover your PiKVM or review what it's doing due to boot failures or due to general network issues A serial console is a convenient and fast way to connect to PiKVM when there is no network, or get boot logs and a console if something goes wrong.
* **Step 1.** Remove the PiKVM from the Target system 1. Remove the PiKVM from the target system.
* **Step 2.** You can reuse the OTG cable for this step, place the USB-C end into the IOIOI port (CON port on the v3), V2 you'll need to get the right TTY to USB cable, we recommend the [RPi Debug Probe](https://www.pishop.us/product/raspberry-pi-debug-probe/) and follow existing RPi TTY serial setups. 2. Connect to the physical UART console:
* **Step 3.** Place the USB-A end into the port you want serial to be accessed, typically done on the host * On PiKVM V3 or V4, you have a built-in USB-UART adapter in your device. Just disconnect the OTG cable and place the USB-C end into `IOIOI` port on V4 (or `CON` port on V3). Place the USB-A end into the port you want serial to be accessed, typically done on the host. If you have a Windows host, you may need to install this [driver](https://www.silabs.com/developers/usb-to-uart-bridge-vcp-drivers), other OS's may not need one.
* **Step 4.** For windows you may need to install this [driver](https://www.silabs.com/developers/usb-to-uart-bridge-vcp-drivers), other OS's may not need one * On DIY PiKVM V1 or V2, you'll need to get the right TTY to USB cable, we recommend the [RPi Debug Probe](https://www.pishop.us/product/raspberry-pi-debug-probe/) and follow existing RPi TTY serial setups.
* **Step 5.** Install Putty (Windows) or use GNU screen (may need to install this on your Host if using another OS) 3. Install GNU Screen on Linux or macOS host, or [Putty](https://www.putty.org/) on Windows.
* **Step 6.** Select the COM port in Putty (you can verify this looking in Device Manager), then select 115200 or use `screen /dev/ttyUSB0 115200` for other OS's 4. Select the COM port in Putty (you can verify this looking in Device Manager), then select 115200, or use `screen /dev/ttyUSB0 115200` for other OS's
* **Step 7.** You should now be able to see and interact with the Serial Port 5. You should now be able to see and interact with the Serial Port.
