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. 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
which uses the regular serial port driver to access the device, and must
therefore be attached to the serial device to which the M101 is connected.
The ldattach(8) command (included in util-linux-ng release 2.14 or later)
can be used for that purpose, 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
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.
The modules accept the following parameters:
Module Parameter Meaning
gigaset debug debug level (see section 3.2.)
startmode initial operation mode (see section 2.5.):
bas_gigaset ) 1=ISDN4linux/CAPI (default), 0=Unimodem
ser_gigaset )
usb_gigaset ) cidmode initial Call-ID mode setting (see section
2.5.): 1=on (default), 0=off
Depending on your distribution you may want to create a separate module
configuration file /etc/modprobe.d/gigaset for these, or add them to a
custom file like /etc/modprobe.conf.local.
2.2. Device nodes for user space programs
------------------------------------
The device can be accessed from user space (eg. by the user space tools

You can also select a "default device" which is used by the frontends when
If you connect more than one device of a type, they will get consecutive
device nodes, eg. /dev/ttyGU1 for a second M105.
You can also set a "default device" for the user space tools to use when
no device node is given as parameter, by creating a symlink /dev/ttyG to
one of them, eg.:
ln -s /dev/ttyGB0 /dev/ttyG
ln -s /dev/ttyGB0 /dev/ttyG
The devices accept the following device specific ioctl calls
(defined in gigaset_dev.h):
ioctl(int fd, GIGASET_REDIR, int *cmd);
If cmd==1, the device is set to be controlled exclusively through the
character device node; access from the ISDN subsystem is blocked.
If cmd==0, the device is set to be used from the ISDN subsystem and does
not communicate through the character device node.
ioctl(int fd, GIGASET_CONFIG, int *cmd);
(ser_gigaset and usb_gigaset only)
If cmd==1, the device is set to adapter configuration mode where commands
are interpreted by the M10x DECT adapter itself instead of being
forwarded to the base station. In this mode, the device accepts the
commands described in Siemens document "AT-Kommando Alignment M10x Data"
for setting the operation mode, associating with a base station and
querying parameters like field strengh and signal quality.
Note that there is no ioctl command for leaving adapter configuration
mode and returning to regular operation. In order to leave adapter
configuration mode, write the command ATO to the device.
ioctl(int fd, GIGASET_BRKCHARS, unsigned char brkchars[6]);
(usb_gigaset only)
Set the break characters on an M105's internal serial adapter to the six
bytes stored in brkchars[]. Unused bytes should be set to zero.
ioctl(int fd, GIGASET_VERSION, unsigned version[4]);
Retrieve version information from the driver. version[0] must be set to
one of:
- GIGVER_DRIVER: retrieve driver version
- GIGVER_COMPAT: retrieve interface compatibility version
- GIGVER_FWBASE: retrieve the firmware version of the base
Upon return, version[] is filled with the requested version information.

2.4. CAPI
----
If the driver is compiled with CAPI support (kernel configuration option
GIGASET_CAPI, experimental) it can also be used with CAPI 2.0 kernel and
user space applications. ISDN4Linux is supported in this configuration

be loaded. The capiinit command (included in the capi4k-utils package)
does this for you.
The CAPI variant of the driver supports legacy ISDN4Linux applications
via the capidrv compatibility driver. The kernel module capidrv.ko must
be loaded explicitly ("modprobe capidrv") if needed.
