Serial port open issue

Ratheesh

Hi Team,

I need your support for identifying the serial port Open issue (Failure during Port opening)

Software Used: Virtual serial port Driver version 10.0.963.0
Qt version : Qt creator 6.0.2 based on Qt 6.2.2
Platform : Windows 10

we have created 4 pairs of virtual serial port separately in windows PC .
we have used these virtual serial ports for testing our application through QtTest framework(Qt API's are used to open or close the serial port).

It is not working properly(unstable) in PC.
Error : Port open failure is happening, and we are not able to find the solution for this problem

Com port configuration :
portName=COM7
baudRate=115200
parity=NoParity
flowControl=NoFlowControl
stopBits=OneStop

All ports are configured with above configuration with different portName

Please support/help us on identifying the issue

Have you tried to check the serial ports connection using one of the existing tools such as PuTTY or Teraterm?
