21 #. Initialize the modem in 0710 mux mode (usually ``AT+CMUX=`` command) through
22 its serial port. Depending on the modem used, you can pass more or less
28 #. Configure the mux using ``GSMIOC_GETCONF_EXT``/``GSMIOC_SETCONF_EXT`` ioctl if needed.
30 #. Configure the mux using ``GSMIOC_GETCONF``/``GSMIOC_SETCONF`` ioctl.
32 #. Configure DLCs using ``GSMIOC_GETCONF_DLCI``/``GSMIOC_SETCONF_DLCI`` ioctl for non-defaults.
34 #. Obtain base gsmtty number for the used serial port.
