Hello everyone,
I have a VM running OS2 (necessary for work), and I would like to add a COM port.

I manage to configure it for communication with my equipment, but when I need to send or receive data, I experience a disconnection after a certain period of time. I can restart it, and with a bit of luck (which is rare), I manage to resume where I left off.

I no longer have this issue with version 5.2.28; however, I am unable to install it on Windows 11.
Do you have a solution for me?

Thank you for advance

Do you mean that it worked with 5.2.28 but doesn't work with a more recent version? Is it possible you know which is the first version where it stopped working?
