Hi there, We're using a SIMCom SIM7100 modem which has the ability to exchange call audio data over a USB serial endpoint⁰. To enable this, the modem needs an AT command after the call has connected, AT+CPCMREG=1, and a command after call has disconnected, AT+CPCMREG=0.
Not knowing the internals of ModemManager too well, I'm wondering if anyone could advise on an appropriate way to add these AT commands for our particular modem? Thanks, Bob ⁰ http://simcomm2m.com/UploadFile/TechnicalFile/SIM7100_SIM7500_SIM7600%20Series_USB%20AUDIO_Application%20Note_V1.03.pdf -- Bob Ham <r...@settrans.net> for (;;) { ++pancakes; }
