      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
+     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
+	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.

+     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

+     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
