GigaSet 307x Device Driver
==========================
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:
307x/417x:
Gigaset SX255isdn
Gigaset SX353isdn
Sinus 45 [AB] isdn (Deutsche Telekom)
Sinus 721X/XA
Vox Chicago 390 ISDN (KPN Telecom)
M101:
Sinus 45 Data 1 (Telekom)
M105:
Gigaset USB Adapter DECT
Sinus 45 Data 2 (Telekom)
Sinus 721 data
Chicago 390 USB (KPN)
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.
For example, Gigaset SX205isdn/Sinus 721 X SE and Gigaset SX303isdn bases
are just versions without answering machine of models known to work, so
they should work just as well; but so far we are lacking positive reports
on these.
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 usb_gigaset (M105) or bas_gigaset (direct USB
connection to the base).
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/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.
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/module/<name>/parameters/cidmode for changing
the CID mode setting (<name> is usb_gigaset or bas_gigaset).
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.
