---------------------
2.1. Modules
-------
To get the device working, you have to load the proper kernel module. You
can do this using
modprobe modulename
where modulename is ser_gigaset (M101), usb_gigaset (M105), or
bas_gigaset (direct USB connection to the base).
For the devices to work, the proper kernel modules have to be loaded.
This normally happens automatically when the system detects the USB
device (base, M105) or when the line discipline is attached (M101). It
can also be triggered manually using the modprobe(8) command, for example
for troubleshooting or to pass module parameters.

The module ser_gigaset provides a serial line discipline N_GIGASET_M101
which drives the device through the regular serial line driver. To use it,
run the Gigaset M101 daemon "gigasetm101d" (also available from
http://sourceforge.net/projects/gigaset307x/) with the device file of the
RS232 port to the M101 as an argument, for example:
gigasetm101d /dev/ttyS1
This will open the device file, set its line discipline to N_GIGASET_M101,
and then sleep in the background, keeping the device open so that the
line discipline remains active. To deactivate it, kill the daemon, for
example with
killall gigasetm101d
before disconnecting the device.
which drives the device through the regular serial line driver. It must
be attached to the serial line to which the M101 is connected with the
ldattach(8) command (requires util-linux-ng release 2.14 or later), for
example:
ldattach GIGASET_M101 /dev/ttyS1
This will open the device file, attach the line discipline to it, and
then sleep in the background, keeping the device open so that the line
discipline remains active. To deactivate it, kill the daemon, for example
with
killall ldattach
before disconnecting the device. To have this happen automatically at
system startup/shutdown on an LSB compatible system, create and activate
an appropriate LSB startup script /etc/init.d/gigaset. (The init name
'gigaset' is officially assigned to this project by LANANA.)
Alternatively, just add the 'ldattach' command line to /etc/rc.local.

Solution:
Select Unimodem mode for all DECT data adapters. (see section 2.4.)

Problem:
You want to configure your USB DECT data adapter (M105) but gigacontr
reports an error: "/dev/ttyGU0: Inappropriate ioctl for device".
Solution:
Recompile the usb_gigaset driver with the kernel configuration option
CONFIG_GIGASET_UNDOCREQ set to 'y'. (see section 2.6.)
