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.
