[FX30S] Working with modem (accepting voice calls) from C app


I’m developping a legacy C application for a FX30S device. From the application, I need to accept a voice call. I would like to use directly AT commands sent to the /dev/ device but I’m not able to identify which is the name of the modem in /dev. Can you please help me with some tips?

Thank you

I found it; it is /dev/ttyAT
