+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.
