During modem initialization we detected the flow control settings supported by the modem, and selected the best one to use from them, notifying it to the device via AT+IFC. The device was therefore instructed to use that flow control setting for data transmission in the TTY (i.e. not during AT control commands). The missing thing was to also configure ourselves our end of the serial port with the same flow control settings when getting into data mode. By doing it ourselves, we avoid requiring any explicit setting in pppd for flow control; pppd can assume the flow control settings are already the expected ones. Worth noting that all this setup is completely ignored for TTYs exposed directly via USB. https://bugs.freedesktop.org/show_bug.cgi?id=100394
