Open your preferred serial communication utility for the COM port.
Note
You can use any serial communication utility in your system. The Vitis IDE provides a serial terminal utility. We will use it throughout the tutorial; select Vitis → Serial Monitor in Vitis IDE to open it.
Note
In Linux, root privilege is required to use UART.
Navigate to Vits → Serial Monitor.
To find the correct COM port in Windows, verify the port details in the Device Manager. In Linux, check the COM port in
/dev.MPSoC UART-0 corresponds to the COM port with Interface-0. Windows Device Manager provides mapping between Interface-x and COM-x.

In the above example, use COM5 for Interface-0 and baud rate 115200.
From the Port dropdown menu, select the port number for Interface-0 (COM3 in this example).
Select 115200 as the baud rate.
Keep the other settings as-is and click OK to connect. The connection status is shown in the Vitis Serial Terminal window.
