[ILUG-BOM] I/O ports access for normal users?

[Rahul Saxena]

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
