+GigaSet 307x Device Driver
+ This driver supports the connection of the Gigaset 307x/417x family of
+ ISDN DECT bases via Gigaset M101 Data, Gigaset M105 Data or direct USB
+ connection. The following devices are reported to be compatible:
+ Siemens Gigaset 3070/3075 isdn
+ Siemens Gigaset 4170/4175 isdn
+ Siemens Gigaset SX205/255
+ Siemens Gigaset SX353
+ T-Com Sinus 45 [AB] isdn
+ T-Com Sinus 721X[A] [SE]
+ Vox Chicago 390 ISDN (KPN Telecom)
+ RS232 data boxes:
+ Siemens Gigaset M101 Data
+ T-Com Sinus 45 Data 1
+ USB data boxes:
+ Siemens Gigaset M105 Data
+ Siemens Gigaset USB Adapter DECT
+ T-Com Sinus 45 Data 2
+ T-Com Sinus 721 data
+ Chicago 390 USB (KPN)
+ See also http://www.erbze.info/sinus_gigaset.htm and
+ We had also reports from users of Gigaset M105 who could use the drivers
+ with SX 100 and CX 100 ISDN bases (only in unimodem mode, see section 2.5.)
+ If you have another device that works with our driver, please let us know.
+ Chances of getting an USB device to work are good if the output of
+ at the command line contains one of the following:
+ ID 0681:0001
+ ID 0681:0002
+ ID 0681:0009
+ ID 0681:0021
+ ID 0681:0022
+ The driver works with the Kernel CAPI subsystem as well as the old
+ ISDN4Linux subsystem, so it can be used with any software which is able
+ to use CAPI 2.0 or ISDN4Linux for ISDN connections (voice or data).
+ There are some user space tools available at
+ which provide access to additional device specific functions like SMS,
+ phonebook or call journal.
+2. How to use the driver
+ 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 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
+ 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 like /etc/modprobe.d/gigaset.conf for these.
+2.2. Device nodes for user space programs
+ The device can be accessed from user space (eg. by the user space tools
+ mentioned in 1.2.) through the device nodes:
+ - /dev/ttyGS0 for M101 (RS232 data boxes)
+ - /dev/ttyGU0 for M105 (USB data boxes)
+ - /dev/ttyGB0 for the base driver (direct USB connection)
+ 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
+ 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);
+ (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);
+ Retrieve version information from the driver. version 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.
+ If the driver is compiled with CAPI support (kernel configuration option
+ GIGASET_CAPI) the devices will show up as CAPI controllers as soon as the
+ corresponding driver module is loaded, and can then be used with CAPI 2.0
+ kernel and user space applications. For user space access, the module
+ capi.ko must be loaded.
+ Legacy ISDN4Linux applications are supported via the capidrv
+ compatibility driver. The kernel module capidrv.ko must be loaded
+ explicitly with the command
+ modprobe capidrv
+ if needed, and cannot be unloaded again without unloading the driver
+ first. (These are limitations of capidrv.)
+ Most distributions handle loading and unloading of the various CAPI
+ modules automatically via the command capiinit(1) from the capi4k-utils
+ package or a similar mechanism. Note that capiinit(1) cannot unload the
+ Gigaset drivers because it doesn't support more than one module per
+ If the driver is compiled without CAPI support (native ISDN4Linux
+ variant), it registers the device with the legacy ISDN4Linux subsystem
+ after loading the module. It can then be used with ISDN4Linux
+ applications only. Most distributions provide some configuration utility
+ for setting up that subsystem. Otherwise you can use some HOWTOs like
+2.5. Unimodem mode
+ In this mode the device works like a modem connected to a serial port
+ (the /dev/ttyGU0, ... mentioned above) which understands the commands
+ ATZ init, reset
+ => OK or ERROR
+ ATDT dial
+ => OK, CONNECT,
+ NO DIAL TONE,
+ NO CARRIER,
+ NO ANSWER
+ <pause>+++<pause> change to command mode when connected
+ ATH hangup
+ You can use some configuration tool of your distribution to configure this
+ "modem" or configure pppd/wvdial manually. There are some example ppp
+ configuration files and chat scripts in the gigaset-VERSION/ppp directory
+ in the driver packages from http://sourceforge.net/projects/gigaset307x/.
+ Please note that the USB drivers are not able to change the state of the
+ control lines. This means you must use "Stupid Mode" if you are using
+ wvdial or you should use the nocrtscts option of pppd.
+ You must also assure that the ppp_async module is loaded with the parameter
+ flag_time=0. You can do this e.g. by adding a line like
+ options ppp_async flag_time=0
+ to an appropriate module configuration file, like
+ Unimodem mode is needed for making some devices [e.g. SX100] work which
+ do not support the regular Gigaset command set. If debug output (see
+ section 3.2.) shows something like this when dialing:
+ CMD Received: ERROR
+ Available Params: 0
+ Connection State: 0, Response: -1
+ gigaset_process_response: resp_code -1 in ConState 0 !
+ Timeout occurred
+ then switching to unimodem mode may help.
+ If you have installed the command line tool gigacontr, you can enter
+ unimodem mode using
+ gigacontr --mode unimodem
+ You can switch back using
+ gigacontr --mode isdn
+ You can also put the driver directly into Unimodem mode when it's loaded,
+ by passing the module parameter startmode=0 to the hardware specific
+ module, e.g.
+ modprobe usb_gigaset startmode=0
+ or by adding a line like
+ options usb_gigaset startmode=0
+ to an appropriate module configuration file, like
+2.6. Call-ID (CID) mode
+ Call-IDs are numbers used to tag commands to, and responses from, the
+ Gigaset base in order to support the simultaneous handling of multiple
+ ISDN calls. Their use can be enabled ("CID mode") or disabled ("Unimodem
+ mode"). Without Call-IDs (in Unimodem mode), only a very limited set of
+ functions is available. It allows outgoing data connections only, but
+ does not signal incoming calls or other base events.
+ DECT cordless data devices (M10x) permanently occupy the cordless
+ connection to the base while Call-IDs are activated. As the Gigaset
+ bases only support one DECT data connection at a time, this prevents
+ other DECT cordless data devices from accessing the base.
+ During active operation, the driver switches to the necessary mode
+ automatically. However, for the reasons above, the mode chosen when
+ the device is not in use (idle) can be selected by the user.
+ - If you want to receive incoming calls, you can use the default
+ settings (CID mode).
+ - If you have several DECT data devices (M10x) which you want to use
+ in turn, select Unimodem mode by passing the parameter "cidmode=0" to
+ the appropriate driver module (ser_gigaset or usb_gigaset).
+ If you want both of these at once, you are out of luck.
+ You can also use the tty class parameter "cidmode" of the device to
+ change its CID mode while the driver is loaded, eg.
+ echo 0 > /sys/class/tty/ttyGU0/cidmode
+2.7. Dialing Numbers
+ The called party number provided by an application for dialing out must
+ be a public network number according to the local dialing plan, without
+ any dial prefix for getting an outside line.
+ Internal calls can be made by providing an internal extension number
+ prefixed with "**" (two asterisks) as the called party number. So to dial
+ eg. the first registered DECT handset, give "**11" as the called party
+ number. Dialing "***" (three asterisks) calls all extensions
+ simultaneously (global call).
+ This holds for both CAPI 2.0 and ISDN4Linux applications. Unimodem mode
+ does not support internal calls.
+2.8. Unregistered Wireless Devices (M101/M105)
+ The main purpose of the ser_gigaset and usb_gigaset drivers is to allow
+ the M101 and M105 wireless devices to be used as ISDN devices for ISDN
+ connections through a Gigaset base. Therefore they assume that the device
+ is registered to a DECT base.
+ If the M101/M105 device is not registered to a base, initialization of
+ the device fails, and a corresponding error message is logged by the
+ driver. In that situation, a restricted set of functions is available
+ which includes, in particular, those necessary for registering the device
+ to a base or for switching it between Fixed Part and Portable Part
+ modes. See the gigacontr(8) manpage for details.
+3.1. Solutions to frequently reported problems
+ You have a slow provider and isdn4linux gives up dialing too early.
+ Load the isdn module using the dialtimeout option. You can do this e.g.
+ by adding a line like
+ options isdn dialtimeout=15
+ to /etc/modprobe.d/gigaset.conf or a similar file.
+ The isdnlog program emits error messages or just doesn't work.
+ Isdnlog supports only the HiSax driver. Do not attempt to use it with
+ other drivers such as Gigaset.
+ You have two or more DECT data adapters (M101/M105) and only the
+ first one you turn on works.
+ Select Unimodem mode for all DECT data adapters. (see section 2.5.)
+ Messages like this:
+ usb_gigaset 3-2:1.0: Could not initialize the device.
+ appear in your syslog.
+ Check whether your M10x wireless device is correctly registered to the
+ Gigaset base. (see section 2.7.)
+3.2. Telling the driver to provide more information
+ Building the driver with the "Gigaset debugging" kernel configuration
+ option (CONFIG_GIGASET_DEBUG) gives it the ability to produce additional
+ information useful for debugging.
+ You can control the amount of debugging information the driver produces by
+ writing an appropriate value to /sys/module/gigaset/parameters/debug, e.g.
+ echo 0 > /sys/module/gigaset/parameters/debug
+ switches off debugging output completely,
+ echo 0x302020 > /sys/module/gigaset/parameters/debug
+ enables a reasonable set of debugging output messages. These values are
+ bit patterns where every bit controls a certain type of debugging output.
+ See the constants DEBUG_* in the source file gigaset.h for details.
+ The initial value can be set using the debug parameter when loading the
+ module "gigaset", e.g. by adding a line
+ options gigaset debug=0
+ to your module configuration file, eg. /etc/modprobe.d/gigaset.conf
+ Generated debugging information can be found
+ - as output of the command
+ - in system log files written by your syslog daemon, usually
+ in /var/log/, e.g. /var/log/messages.
+3.3. Reporting problems and bugs
+ If you can't solve problems with the driver on your own, feel free to
+ use one of the forums, bug trackers, or mailing lists on
+ or write an electronic mail to the maintainers.
+ Try to provide as much information as possible, such as
+ - distribution
+ - kernel version (uname -r)
+ - gcc version (gcc --version)
+ - hardware architecture (uname -m, ...)
+ - type and firmware version of your device (base and wireless module,
+ if any)
+ - output of "lsusb -v" (if using an USB device)
+ - error messages
+ - relevant system log messages (it would help if you activate debug
+ output as described in 3.2.)
+ For help with general configuration problems not specific to our driver,
+ such as isdn4linux and network configuration issues, please refer to the
+ appropriate forums and newsgroups.
+3.4. Reporting problem solutions
+ If you solved a problem with our drivers, wrote startup scripts for your
+ distribution, ... feel free to contact us (using one of the places
+ mentioned in 3.3.). We'd like to add scripts, hints, documentation
+ to the driver and/or the project web page.
