2.1. Modules
-------
- To get the device working, you have to load the proper kernel module. You
- can do this using
- modprobe modulename
- where modulename is ser_gigaset (M101), usb_gigaset (M105), or
- bas_gigaset (direct USB connection to the base).
+ 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 drives the device through the regular serial line driver. To use it,
- run the Gigaset M101 daemon "gigasetm101d" (also available from
- http://sourceforge.net/projects/gigaset307x/) with the device file of the
- RS232 port to the M101 as an argument, for example:
- gigasetm101d /dev/ttyS1
- This will open the device file, set its line discipline to N_GIGASET_M101,
- 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 gigasetm101d
- before disconnecting the device.
+ 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
+ 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.
