The modem is a wakeup device. IIRC there's a separate GPIO line with interrupts specifically for this.

That's handy, thanks for letting me know! I assume that applications that are resumed from suspension can then continue checking for incoming phone calls and alert the user when necessary, much like how (from my 'experiments' with the PinePhone) pressing the power button to wake the phone will still allow applications to capture the keypress event.
