staging: remove isdn capi drivers

Browse Source 
As described in drivers/staging/isdn/TODO, the drivers are all
assumed to be unmaintained and unused now, with gigaset being the
last one to stop being maintained after Paul Bolle lost access
to an ISDN network.

The CAPI subsystem remains for now, as it is still required by
bluetooth/cmtp.

================================
Driver for active AVM Controller
================================
The driver provides a kernel capi2.0 Interface (kernelcapi) and
on top of this a User-Level-CAPI2.0-interface (capi)
and a driver to connect isdn4linux with CAPI2.0 (capidrv).
The lowlevel interface can be used to implement a CAPI2.0
also for passive cards since July 1999.
The author can be reached at calle@calle.in-berlin.de.
The command avmcapictrl is part of the isdn4k-utils.
t4-files can be found at ftp://ftp.avm.de/cardware/b1/linux/firmware
Currently supported cards:
- B1 ISA (all versions)
- B1 PCI
- T1/T1B (HEMA card)
- M1
- M2
- B1 PCMCIA
Installing
----------
You need at least /dev/capi20 to load the firmware.
::
mknod /dev/capi20 c 68 0
mknod /dev/capi20.00 c 68 1
mknod /dev/capi20.01 c 68 2
.
.
.
mknod /dev/capi20.19 c 68 20
Running
-------
To use the card you need the t4-files to download the firmware.
AVM GmbH provides several t4-files for the different D-channel
protocols (b1.t4 for Euro-ISDN). Install these file in /lib/isdn.
if you configure as modules load the modules this way::
insmod /lib/modules/current/misc/capiutil.o
insmod /lib/modules/current/misc/b1.o
insmod /lib/modules/current/misc/kernelcapi.o
insmod /lib/modules/current/misc/capidrv.o
insmod /lib/modules/current/misc/capi.o
if you have an B1-PCI card load the module b1pci.o::
insmod /lib/modules/current/misc/b1pci.o
and load the firmware with::
avmcapictrl load /lib/isdn/b1.t4 1
if you have an B1-ISA card load the module b1isa.o
and add the card by calling::
avmcapictrl add 0x150 15
and load the firmware by calling::
avmcapictrl load /lib/isdn/b1.t4 1
if you have an T1-ISA card load the module t1isa.o
and add the card by calling::
avmcapictrl add 0x450 15 T1 0
and load the firmware by calling::
avmcapictrl load /lib/isdn/t1.t4 1
if you have an PCMCIA card (B1/M1/M2) load the module b1pcmcia.o
before you insert the card.
Leased Lines with B1
--------------------
Init card and load firmware.
For an D64S use "FV: 1" as phone number
For an D64S2 use "FV: 1" and "FV: 2" for multilink
or "FV: 1,2" to use CAPI channel bundling.

GigaSet 307x Device Driver
==========================
1. Requirements
=================
1.1. Hardware
-------------
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:
Bases:
- 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
(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.

1. About the driver
===================
The drivers/isdn/hysdn subdir contains a driver for HYPERCOPEs active
PCI isdn cards Champ, Ergo and Metro. To enable support for this cards
enable ISDN support in the kernel config and support for HYSDN cards in
the active cards submenu. The driver may only be compiled and used if
support for loadable modules and the process filesystem have been enabled.
These cards provide two different interfaces to the kernel. Without the
optional CAPI 2.0 support, they register as ethernet card. IP-routing
to a ISDN-destination is performed on the card itself. All necessary
handlers for various protocols like ppp and others as well as config info
and firmware may be fetched from Hypercopes WWW-Site www.hypercope.de.
With CAPI 2.0 support enabled, the card can also be used as a CAPI 2.0
compliant devices with either CAPI 2.0 applications
(check isdn4k-utils) or -using the capidrv module- as a regular
isdn4linux device. This is done via the same mechanism as with the
active AVM cards and in fact uses the same module.
2. Loading/Unloading the driver
===============================
The module has no command line parameters and auto detects up to 10 cards
in the id-range 0-9.
If a loaded driver shall be unloaded all open files in the /proc/net/hysdn
subdir need to be closed and all ethernet interfaces allocated by this
driver must be shut down. Otherwise the module counter will avoid a module
unload.
If you are using the CAPI 2.0-interface, make sure to load/modprobe the
kernelcapi-module first.
If you plan to use the capidrv-link to isdn4linux, make sure to load
capidrv.o after all modules using this driver (i.e. after hysdn and
any avm-specific modules).
3. Entries in the /proc filesystem
==================================
When the module has been loaded it adds the directory hysdn in the
/proc/net tree. This directory contains exactly 2 file entries for each
card. One is called cardconfX and the other cardlogX, where X is the
card id number from 0 to 9.
The cards are numbered in the order found in the PCI config data.
4. The /proc/net/hysdn/cardconfX file
=====================================
This file may be read to get by everyone to get info about the cards type,
actual state, available features and used resources.
The first 3 entries (id, bus and slot) are PCI info fields, the following
type field gives the information about the cards type:
- 4 -> Ergo card (server card with 2 b-chans)
- 5 -> Metro card (server card with 4 or 8 b-chans)
- 6 -> Champ card (client card with 2 b-chans)
The following 3 fields show the hardware assignments for irq, iobase and the
dual ported memory (dp-mem).
The fields b-chans and fax-chans announce the available card resources of
this types for the user.
The state variable indicates the actual drivers state for this card with the
following assignments.
- 0 -> card has not been booted since driver load
- 1 -> card booting is actually in progess
- 2 -> card is in an error state due to a previous boot failure
- 3 -> card is booted and active
And the last field (device) shows the name of the ethernet device assigned
to this card. Up to the first successful boot this field only shows a -
to tell that no net device has been allocated up to now. Once a net device
has been allocated it remains assigned to this card, even if a card is
rebooted and an boot error occurs.
Writing to the cardconfX file boots the card or transfers config lines to
the cards firmware. The type of data is automatically detected when the
first data is written. Only root has write access to this file.
The firmware boot files are normally called hyclient.pof for client cards
and hyserver.pof for server cards.
After successfully writing the boot file, complete config files or single
config lines may be copied to this file.
If an error occurs the return value given to the writing process has the
following additional codes (decimal):
==== ============================================
1000 Another process is currently bootng the card
1001 Invalid firmware header
1002 Boards dual-port RAM test failed
1003 Internal firmware handler error
1004 Boot image size invalid
1005 First boot stage (bootstrap loader) failed
1006 Second boot stage failure
1007 Timeout waiting for card ready during boot
1008 Operation only allowed in booted state
1009 Config line too long
1010 Invalid channel number
1011 Timeout sending config data
==== ============================================
Additional info about error reasons may be fetched from the log output.
5. The /proc/net/hysdn/cardlogX file
====================================
The cardlogX file entry may be opened multiple for reading by everyone to
get the cards and drivers log data. Card messages always start with the
keyword LOG. All other lines are output from the driver.
The driver log data may be redirected to the syslog by selecting the
appropriate bitmask. The cards log messages will always be send to this
interface but never to the syslog.
A root user may write a decimal or hex (with 0x) value t this file to select
desired output options. As mentioned above the cards log dat is always
written to the cardlog file independent of the following options only used
to check and debug the driver itself:
For example::
echo "0x34560078" > /proc/net/hysdn/cardlog0
to output the hex log mask 34560078 for card 0.
The written value is regarded as an unsigned 32-Bit value, bit ored for
desired output. The following bits are already assigned:
========== ============================================================
0x80000000 All driver log data is alternatively via syslog
0x00000001 Log memory allocation errors
0x00000010 Firmware load start and close are logged
0x00000020 Log firmware record parser
0x00000040 Log every firmware write actions
0x00000080 Log all card related boot messages
0x00000100 Output all config data sent for debugging purposes
0x00000200 Only non comment config lines are shown wth channel
0x00000400 Additional conf log output
0x00001000 Log the asynchronous scheduler actions (config and log)
0x00100000 Log all open and close actions to /proc/net/hysdn/card files
0x00200000 Log all actions from /proc file entries
0x00010000 Log network interface init and deinit
========== ============================================================
6. Where to get additional info and help
========================================
If you have any problems concerning the driver or configuration contact
the Hypercope support team (support@hypercope.de) and or the authors
Werner Cornelius (werner@isdn4linux or cornelius@titro.de) or
Ulrich Albrecht (ualbrecht@hypercope.de).

TODO: Remove in late 2019 unless there are users
I tried to find any indication of whether the capi drivers are
still in use, and have not found anything from a long time ago.
With public ISDN networks almost completely shut down over the past 12
months, there is very little you can actually do with this hardware. The
main remaining use case would be to connect ISDN voice phones to an
in-house installation with Asterisk or LCR, but anyone trying this in
turn seems to be using either the mISDN driver stack, or out-of-tree
drivers from the hardware vendors.
I may of course have missed something, so I would suggest moving
these into drivers/staging/ just in case someone still uses one
of the three remaining in-kernel drivers (avm, hysdn, gigaset).
If nobody complains, we can remove them entirely in six months,
or otherwise move the core code and any drivers that are still
needed back into drivers/isdn.

menuconfig ISDN_DRV_GIGASET
tristate "Siemens Gigaset support"
depends on TTY
select CRC_CCITT
select BITREVERSE
help
This driver supports the Siemens Gigaset SX205/255 family of
ISDN DECT bases, including the predecessors Gigaset 3070/3075
and 4170/4175 and their T-Com versions Sinus 45isdn and Sinus
721X.
If you have one of these devices, say M here and for at least
one of the connection specific parts that follow.
This will build a module called "gigaset".
Note: If you build your ISDN subsystem (ISDN_CAPI or ISDN_I4L)
as a module, you have to build this driver as a module too,
otherwise the Gigaset device won't show up as an ISDN device.
if ISDN_DRV_GIGASET
config GIGASET_CAPI
bool "Gigaset CAPI support"
depends on ISDN_CAPI='y'||(ISDN_CAPI='m'&&ISDN_DRV_GIGASET='m')
default 'y'
help
Build the Gigaset driver as a CAPI 2.0 driver interfacing with
the Kernel CAPI subsystem. To use it with the old ISDN4Linux
subsystem you'll have to enable the capidrv glue driver.
(select ISDN_CAPI_CAPIDRV.)
Say N to build the old native ISDN4Linux variant.
If unsure, say Y.
config GIGASET_BASE
tristate "Gigaset base station support"
depends on USB
help
Say M here if you want to use the USB interface of the Gigaset
base for connection to your system.
This will build a module called "bas_gigaset".
config GIGASET_M105
tristate "Gigaset M105 support"
depends on USB
help
Say M here if you want to connect to the Gigaset base via DECT
using a Gigaset M105 (Sinus 45 Data 2) USB DECT device.
This will build a module called "usb_gigaset".
config GIGASET_M101
tristate "Gigaset M101 support"
help
Say M here if you want to connect to the Gigaset base via DECT
using a Gigaset M101 (Sinus 45 Data 1) RS232 DECT device.
This will build a module called "ser_gigaset".
config GIGASET_DEBUG
bool "Gigaset debugging"
help
This enables debugging code in the Gigaset drivers.
If in doubt, say yes.
