-2.4. CAPI
+2.3. CAPI
      ----
      If the driver is compiled with CAPI support (kernel configuration option
-     GIGASET_CAPI, experimental) it can also be used with CAPI 2.0 kernel and
-     user space applications. For user space access, the module capi.ko must
-     be loaded. The capiinit command (included in the capi4k-utils package)
-     does this for you.
-
-     The CAPI variant of the driver supports legacy ISDN4Linux applications
-     via the capidrv compatibility driver. The kernel module capidrv.ko must
-     be loaded explicitly with the command
+     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.)
 
-     The note about unimodem mode in the preceding section applies here, too.
-
-2.5. Unimodem mode
-     -------------
-     This is needed for some devices [e.g. SX100] as they have problems with
-     the "normal" commands.
+     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.
 
-     If you have installed the command line tool gigacontr, you can enter
-     unimodem mode using
-         gigacontr --mode unimodem
-     You can switch back using

+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
 
-     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

+     The called party number provided by an application for dialing out must

+
+     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).
