API Configuration - VM204

Hello, I have several VM204 boards.

I use it through the API control from a VB.NET program in Visual Basic.

My problem is that when I send an API command to the board, it responds with a text that Visual Basic interprets as a .json file.

Upon receiving this .json file, the program stops and asks if I want to open or download it.

Is it possible to disable board responses? Or modify the firmware to be able to edit those answers?

It would be very helpful if you could give me a solution to this.

Thanks a lot.
