The ISDN documentation is a mix of admin guide, uAPI and kAPI. Ideally, it should be split. Yet, not sure if it would worth the troble. Anyway, we have the same kind of mix on several drivers specific documentation. So, just like the others, keep the directory at the root Documentation/ tree, just adding a pointer to it at the kAPI section, as the documentation was written with the Kernel developers in mind.

|
|
http://gigaset307x.sourceforge.net/
|
|
|
|
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::
|
|
|
|
lsusb
|
|
|
|
at the command line contains one of the following::
|
|
|
|
ID 0681:0001
|
|
ID 0681:0002
|
|
ID 0681:0009
|
|
ID 0681:0021
|
|
ID 0681:0022
|
|
|
|
1.2. Software
|
|
-------------
|
|
|
|
The driver works with the Kernel CAPI subsystem and can be used with any
|
|
software which is able to use CAPI 2.0 for ISDN connections (voice or data).
|
|
|
|
There are some user space tools available at
|
|
https://sourceforge.net/projects/gigaset307x/
|
|
which provide access to additional device specific functions like SMS,
|
|
phonebook or call journal.
|
|
|
|
|
|
2. How to use the driver
|
|
==========================
|
|
|
|
2.1. Modules
|
|
------------
|
|
|
|
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
|
|
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.
|
|
|
|
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=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[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.
|
|
|
|
2.3. 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.
|
|
|
|
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
|
|
driver.
|
|
|
|
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
|
|
ATD
|
|
ATDT dial
|
|
=> OK, CONNECT,
|
|
BUSY,
|
|
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 https://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::
|
|
|
|
/etc/modprobe.d/gigaset.conf.
|
|
|
|
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::
|
|
|
|
/etc/modprobe.d/gigaset.conf
|
|
|
|
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
|
|
--------------------
|
|
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).
|
|
|
|
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. Troubleshooting
|
|
====================
|
|
|
|
3.1. Solutions to frequently reported problems
|
|
----------------------------------------------
|
|
|
|
Problem:
|
|
You have a slow provider and isdn4linux gives up dialing too early.
|
|
Solution:
|
|
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.
|
|
|
|
Problem:
|
|
The isdnlog program emits error messages or just doesn't work.
|
|
Solution:
|
|
Isdnlog supports only the HiSax driver. Do not attempt to use it with
|
|
other drivers such as Gigaset.
|
|
|
|
Problem:
|
|
You have two or more DECT data adapters (M101/M105) and only the
|
|
first one you turn on works.
|
|
Solution:
|
|
Select Unimodem mode for all DECT data adapters. (see section 2.5.)
|
|
|
|
Problem:
|
|
Messages like this::
|
|
|
|
usb_gigaset 3-2:1.0: Could not initialize the device.
|
|
|
|
appear in your syslog.
|
|
Solution:
|
|
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::
|
|
|
|
dmesg
|
|
|
|
- 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
|
|
|
|
https://sourceforge.net/projects/gigaset307x
|
|
|
|
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.)
|
|
|
|
