hi everyone,

I was tryign to read/write bits to 0x378 I/O port, using the ioperm() system call. But this allows only the root to access.

HOw do normal users access the port? i did read about SETUID(), but i dont really understand how it works for me ??

does anyone have any pointers on this ??

Also i am trying to uderstand how ot access using read and write. for that i would need to add the user as part of the group, which can access /dev/port.

How do i add myself to the group? i guess.. in that case i wont be in my original group.

Thanks for reading
