Have you tried to set the ID_MM_TTY_FLOW_CONTROL udev tag in the TTY port so that flow control settings are applied by ModemManager before the connection is started? E.g. ID_MM_TTY_FLOW_CONTROL set to "rts-cts" or to "xon-xoff" Also, if using 115200, have you set ID_MM_TTY_BAUDRATE to 115200 as well as a udev tag in the TTY port? The default in MM is 57600 really. -- Aleksander https://aleksander.es _______________________________________________ networkmanager-list mailing list networkmanager-list@gnome.org https://mail.gnome.org/mailman/listinfo/networkmanager-list
