Hey all,
I was writing a parallel port device driver, where all I needed to do was outb a character string to the port, problem is when i do use
echo -n "11001100" > /dev/mydevice for instance
the values on the parallel port do change, but differently to what they have been issued to be by the above command, does anyone know why that machine is doing something so simple wrong???
The code I have used in the according device drivers write method uses an outb() function to simply put the incoming string on 0x378 address.
Any idea?
Regards
Hexic
