O.k. Thanks for the comment, actually I was also thinking about this. The problem is that I cannot insert any additional serial ports or interfaces (hardware). I have a small PC(PC104 Dimensions) with two serial ports, one for a gps modul and the other for a packet radio modem. On the parallel port I have a LCD monitor. And a small numberblock keyboard connected to the keyboard connector. With the graphics card everything works fine - the problem is that I don't have any room for the card in the box and I really don't need it because of the lcd module (execept for the keyboard ;-)).
Is there any way to tell the console/tty driver to start without a graphics card ? How does the system recognise the ctrl-alt-del ? (because this works anyway)
Ok I think my task is very special but I wondered a bit because I didn't expect the console, or tty drivers to stop without the graphics card.
I hope there is a solution for this ;-)
