I have a question about writing to parallel ports. I am trying to make a basic C program to write simple data to a parallel port, but when I try, I get an error on opening /dev/lpt0 as "Device Busy" I tried echo 255 > /dev/lpt0, and also got "Device Busy". When looking at all my processes, I didn't see anything that visibly took control of /dev/lpt0. In dmesg, I get both ppc0 and lpt0 detected with an IRQ and IO address fine. What could be wrong?
