Mauro Carvalho Chehab 5a5e045bb3 docs: isdn: convert to ReST and add to kAPI bookset 
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.

(archived at https://web.archive.org/web/20100717020421/http://www.erbze.info:80/sinus_gigaset.htm ) and
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.)
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.
