Using RS232 Terminal as input device

[hbruegge at rockwellcollins.com]

Hi all


I am using the kernel (2.6.15) in an ppc-based embedded system through a 
serial console on ttyS0 with no problems.

Now I attached a graphic card to the system, which is correctly 
recognized and initialised by the Kernel. If I add "console=tty0 
console=ttyS0,57600" to the bootargs, I have the boot messages of the 
kernel on the screen and a login on the ttyS0.

What I now want to do is to disable the serial console and use the 
graphic card as output and the raw character data (ASCII) coming in from 
the terminal connected to the rs232 as input.

I have a login on the screen, if I delete the line console=ttyS0,57600 
from the bootargs, but unfortunately no input if a key is pressed on the 
terminal keyboard.


So my problem and question is, apart from not totally understanding the 
input device system of 2.6.x ;-)
Has anyone ever done that?
Is it just a kernel configuration problem? If so what modules have to be 
compiled in?
Are there any good documentaion about the new input device system ?

Basically I am totally confused ;-), so any ideas are appreciated.

Cheers

Harald
