OS - Windows 10
Qt version - Qt5

In my Qt GUI, I have a QComboBox for the COM port selection and "connect" push button. When I click on connect button, able to configure serial port properly and open() call is successful.

I am trying to build an serial port application between PC and a device.

But I am able to see a serial console terminal on clicking connect button. Can somebody help me out here!

Thanks in Advance,
