Siemens SL45i gnokii 0.6.3 not running

[Markus Tauchnitz]

Hi,


I'm trying to get my SL45i working with gnokii. I've compiled it on my 
own on a debian woody system.
gnokii --monitor says:

---- begin


GNOKII Version 0.6.3

Couldn't open ATBUS device: Eingabe-/Ausgabefehler

Quitting.

-- end

I'm sure that i try to access the right device.
So whats wrong with my serial device?

Thanks,

Markus
