Sending a byte to the parallel port
Greetings,
A sort of newbie question... I would like to control a couple of stepper motors via the parallel port using C code. I have discovered in Linux, the ioperm() function is required before the outportb() function can be used to send a byte to the parallel port. My problem is ioperm() can only be executed as root. I have discovered setuid is frowned upon to get root privlidges. Can anyone suggest a simple way to send a byte to the parallel port (with code examples if possible?) I'm using Fedora 10 TIA |
