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 (If you have not yet enabled the serial monitor or you cannot see it under the vitis tab then enable it by navigating to Vits → New Feature Preview, select Serial Monitor and then select Enable).
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.
