| 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] |

 |  | 
 |      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 |

 |  | 
 |      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 2.5.) | 
 |      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 as well as the old | 
 |      ISDN4Linux subsystem, so it can be used with any software which is able | 
 |      to use CAPI 2.0 or ISDN4Linux for ISDN connections (voice or data). | 
 |  | 
 |      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 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=ISDN4linux/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 /etc/modprobe.d/gigaset for these, or add them to a | 
 |      custom file like /etc/modprobe.conf.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) | 
 |  | 
 |      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 | 
 |      ---- | 
 |      If the driver is compiled with CAPI support (kernel configuration option | 
 |      GIGASET_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. | 
 |  | 
 |      Legacy ISDN4Linux applications are supported via the capidrv | 
 |      compatibility driver. The kernel module capidrv.ko must be loaded | 
 |      explicitly with the command | 
 |         modprobe capidrv | 
 |      if needed, and cannot be unloaded again without unloading the driver | 
 |      first. (These are limitations of capidrv.) | 
 |  | 
 |      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. | 
 |  | 
 | 2.4. ISDN4Linux | 
 |      ---------- | 
 |      If the driver is compiled without CAPI support (native ISDN4Linux | 
 |      variant), it registers the device with the legacy ISDN4Linux subsystem | 
 |      after loading the module. It can then be used with ISDN4Linux | 
 |      applications only. Most distributions provide some configuration utility | 
 |      for setting up that subsystem. Otherwise you can use some HOWTOs like | 
 |          http://www.linuxhaven.de/dlhp/HOWTO/DE-ISDN-HOWTO-5.html | 
 |  | 
 |  | 
 | 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 http://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 | 
 |      or /etc/modprobe.conf.local. | 
 |  | 
 |      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 | 
 |      or /etc/modprobe.conf.local. | 
 |  | 
 | 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 | 
 |      --------------- | 
 |      The called party number 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). | 
 |  | 
 |      This holds for both CAPI 2.0 and ISDN4Linux applications. 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, /etc/modprobe.conf.local 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 or | 
 |      /etc/modprobe.conf.local. | 
 |  | 
 |      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 |
