Yes, it is USB CDC ACM.
How can I find out if my device supports RTS toggling or not?
Host generates a request when I toggle DTR from terminal and it also
updates the RTS status correctly in the same request.
But it is not generating the request when I toggle RTS from terminal.

I also tried using windows default driver. But it showing 'Device cannot
start (Error 10)'.
How can I make my device compatible with windows default driver?



With regards,
