I use the "Virtual Serial" driver example as base project for my own driver.

The driver itsself has been adapeted with a TCP-Socket-Connection (Client). The driver acts as "COM to TCP Adapter.

I installed more than one driver (in this case two). When I connect with a Serial-Tool (RealTerm) to the COM-Ports (24 and 25) an request some data from the driver, the response from the driver is visualized in the wrong terminal.

It's seems that this problem only occur on Windows10 (I currently use Version 1803).
We use this driver on Windows7, Windows8 without any problems.


Are there any known issues concering this problem?
What can cause this behaviour?


Are there any improvements done in the sample project "Virtual serial driver sample 2"?

Thanks!
