Hi Corona688
Sorry for the late reply, but it took me a while to test your recommendation about real-time signals.

My system also have a CLI and it seems that using real time signals interrupt the CLI. Is it the common behaviour of CLI with RT signals or is it something I need to check in our impelemntation of the CLI ?

Thank you!
