Parallel Port Pin driver for Linux 2.6: ppin

This kernel module will register the /dev/ppin (10, 151) device which controls up to eight pins through the first parallel port.

Documentation

Please note that documentation is mostly lacking at the moment. Use the source, luke!

Controlling the pins is as easy as echo num state >/dev/ppin, where num is 0 to 7 and state is one of on or off. For example echo 3 on >/dev/ppin switches the 3rd pin on.

You can read the status of the pins with cat /dev/ppin.
