About Parallel port
I have written one small application for accessing parallel port. I used ioperm system call to get the permission for parallel port. when i want to run that application it needs root permission. Can any one suggest how make that application run for normal users also. i.e can i able to use ioperm system call as a user with out root permissions
ioperm is a systemcall, it needs to be called by root only. May be you can try for a workaround, try using `sudo` for the regular users to get the root permission.
