Serielle Schnittstelle
Hallo Listenbewohner,
ich bekomme meine serielle Schnittstelle nicht zum Laufen.
Ich verwende Debian 4 Etch stable und habe gerade erst ein apt-get
upgrade und apt-get dist-upgrade gemacht um sicherzustellen, das ich die
aktuellsten Sachen habe.
Den Kernel habe ich so erweitert, dass er nun mehr als 4 serielle
Schnittstellen verwalten kann.
Leider funktioniert meine serielle Schnittstelle allerdings weiterhin nicht.
Könnt Ihr mir helfen?
