Can you explain more clearly for me? I really don't specialize in programming. This project is really a bit overwhelming
Thank you

Solution 1

The driver will have to redirect the data directly to the second loaded driver, or to a software which will do that. You will have to implement a driver for that yourself providing the interface for that.

There is also software for doing that.
You can check i.e. com0com, which is under GPL.

If you require testing your software, you can also use two USB serial adapters and just connect them.

Solution 2

You will have to implement a driver redirecting the data to memory instead of hardware. You will also need a bit of software to push the data from one side to the other or at least to configure the driver to directly do that.

If you don't want to do it yourself, you can check com0com or just connect two serial adapters together.
