It sounds like the one in FreeBSD.. It's a bus which allows you to connect different drivers to the parallel port without them conflicting - eg lpt and ppi (which is a "geek port"). The ppi interface is pretty simple - open /dev/ppiX and do ioctl's on it to frob bits - the Atmel AVR programming tool avrdude uses it if you want to see some example code. -- Daniel O'Connor software and network engineer for Genesis Software - http://www.gsoft.com.au "The nice thing about standards is that there are so many of them to choose from." -- Andrew Tanenbaum GPG Fingerprint - 5596 B766 97C0 0E94 4347 295E E593 DC20 7B3F CE8C
