|
|
==========================
|
|
|
|
1. Requirements
|
|
------------
|
|
1.1. Hardware
|
|
--------
|
|
This release 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
|
|

|
|
|
|
See also http://www.erbze.info/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 2.4.)
|
|
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 ISDN4linux and so can be used with any software
|
|
which is able to use ISDN4linux for ISDN connections (voice or data).
|
|
CAPI4Linux support is planned but not yet available.
|
|
|
|
There are some user space tools available at
|
|
http://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
|
|
-------
|
|
To get the device working, you have to load the proper kernel module. You
|
|
can do this using
|
|
modprobe modulename
|
|
where modulename is ser_gigaset (M101), usb_gigaset (M105), or
|
|
bas_gigaset (direct USB connection to the base).
|
|
|
|
The module ser_gigaset provides a serial line discipline N_GIGASET_M101
|
|
which drives the device through the regular serial line driver. To use it,
|
|
run the Gigaset M101 daemon "gigasetm101d" (also available from
|
|
http://sourceforge.net/projects/gigaset307x/) with the device file of the
|
|
RS232 port to the M101 as an argument, for example:
|
|
gigasetm101d /dev/ttyS1
|
|
This will open the device file, set its line discipline to N_GIGASET_M101,
|
|
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 gigasetm101d
|
|
before disconnecting the device.
|
|
|
|
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)
|
|
|
|
You can also select a "default device" which is used by the frontends 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
|
|
|
|
2.3. ISDN4linux
|
|
----------
|
|
This is the "normal" mode of operation. After loading the module you can
|
|
set up the ISDN system just as you'd do with any ISDN card.
|
|
Your distribution should provide some configuration utility.
|
|
If not, you can use some HOWTOs like
|
|
http://www.linuxhaven.de/dlhp/HOWTO/DE-ISDN-HOWTO-5.html
|
|
If this doesn't work, because you have some recent device like SX100 where
|
|
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
|
|
you might need to use unimodem mode:
|
|
|
|
2.4. Unimodem mode
|
|
-------------
|
|
This is needed for some devices [e.g. SX100] as they have problems with
|
|
the "normal" commands.
|
|
|
|
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 load the driver using e.g.
|
|
modprobe usb_gigaset startmode=0
|
|
to prevent the driver from starting in "isdn4linux 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 http://sourceforge.net/projects/gigaset307x/.
|
|
Please note that the USB drivers are not able to change the state of the
|
|
control lines (the M105 driver can be configured to use some undocumented
|
|
control requests, if you really need the control lines, though). 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 /etc/modprobe.conf. If your distribution has some local module
|
|
configuration file like /etc/modprobe.conf.local,
|
|
using that should be preferred.
|
|
|
|
2.5. 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 driver ("modprobe usb_gigaset cidmode=0" or modprobe.conf).
|
|
|
|
If you want both of these at once, you are out of luck.
|
|
|
|
You can also use /sys/class/tty/ttyGxy/cidmode for changing the CID mode
|
|
setting (ttyGxy is ttyGU0 or ttyGB0).
|
|
|
|
2.6. M105 Undocumented USB Requests
|
|
------------------------------
|
|
|
|
The Gigaset M105 USB data box understands a couple of useful, but
|
|
undocumented USB commands. These requests are not used in normal
|
|
operation (for wireless access to the base), but are needed for access
|
|
to the M105's own configuration mode (registration to the base, baudrate
|
|
and line format settings, device status queries) via the gigacontr
|
|
utility. Their use is disabled in the driver by default for safety
|
|
reasons but can be enabled by setting the kernel configuration option
|
|
"Support for undocumented USB requests" (GIGASET_UNDOCREQ) to "Y" and
|
|
recompiling.
|
|
|
|
|
|
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.conf. If your distribution has some local module
|
|
configuration file like /etc/modprobe.conf.local,
|
|
using that should be preferred.
|
|
|
|
Problem:
|
|
Your isdn script aborts with a message about isdnlog.
|
|
Solution:
|
|
Try deactivating (or commenting out) isdnlog. This driver does not
|
|
support it.
|
|
|
|
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 2.4.)
|
|
|
|
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 0x10a020 > /sys/module/gigaset/parameters/debug
|
|
enables the standard 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 /etc/modprobe.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
|
|
http://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.
