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: 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 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 ------- 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 drives the device through the regular serial line driver. It must be attached to the serial line to which the M101 is connected with the ldattach(8) command (requires util-linux-ng release 2.14 or later), 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. 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 +++ 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 controlled by the kernel configuration option "Support for undocumented USB requests" (CONFIG_GIGASET_UNDOCREQ). If you encounter error code -ENOTTY when trying to use some features of the M105, try setting that option to "y" via 'make {x,menu}config' and recompiling the driver. 2.7. 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. For the M105, these commands require the "Support for undocumented USB requests" configuration option (see section 2.6.) to be enabled. 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.) Problem: You want to configure your USB DECT data adapter (M105) but gigacontr reports an error: "/dev/ttyGU0: Inappropriate ioctl for device". Solution: Recompile the usb_gigaset driver with the kernel configuration option CONFIG_GIGASET_UNDOCREQ set to 'y'. (see section 2.6.) 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 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. 4.
