I have study Legato Getting Started guid and try to test. But I can’t using CM command and I have no idea how to debug it. So I have some question as below. 1. Why the CM command didn’t response(cm.png) , Do I miss something? And what’s the log means?

I have the same Problem as okqqkimo1, although modemService is started. I´ve checked the startup Messages and tried both with and without SIM Card, but i can´t get any response. Strangely i also don´t get any log with `cm data` or `cm data info` Thanks. ---
