Simple driver for /dev/coffee: How install it: --------------- You'll have to change the secure level of the kernel (see securelevel(7)): In /etc/rc.securelevel: change "securelevel=1" to "securelevel=-1". Copy coffee.tar.gz in /usr/src/lkm/ untar it. cd /usr/src/lkm/coffee/ make make load Next step: creating the /dev/ entry of the driver: Do `modstat`, and take the major number of the driver, `mknod coffee c $MAJOR 0` That's it. How it works: ------------- `echo capuccino > /dev/coffee` puts the Coffee machine plugged on the parallel port of the PC on, assuming you've put coffee and water in :) `cat /dev/coffee` puts it off. Good drink. :)
