I asked vojtech@xxxxxxx as one of the driver developer

this is how I did it (just prototype, with implicite line discipline)

(neccessary just one folder and two files)
1. copy template linux-source/drivers/input/joystick/magellan.c
2. insert in line 90  :
    printk("%s:\"%s\"\n",__FUNCTION__, data);
3. make and insert it
4. inputattach --magellan /dev/ttyS0 &
5. date > /dev/ttyS0
6. dmesg | tail

voilà!

[output von dmesg]

    [27336.486980] serio: Serial port ttyS0
    [27336.487270] input: LogiCad3D Magellan / SpaceMouse as
/class/input/input6 [27336.518603] magellan_process_packet:"Mi  6 Jun
