Subject: [PATCH 11/11] isdn/gigaset: remove EXPERIMENTAL tag from GIGASET_CAPI
The CAPI variant of the Gigaset drivers can, in combination with
capidrv, now fully replace the legacy ISDN4Linux variant. All
reported problems have been fixed. So remove the EXPERIMENTAL tag
from the Kconfig option selecting it, and adapt the documentation
accordingly to encourage users to switch to it.
Impact: documentation/status update, no functional change

----
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
- gigacontr --mode isdn
+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
- options usb_gigaset startmode=0
- to an appropriate module configuration file, like /etc/modprobe.d/gigaset
- or /etc/modprobe.conf.local.
