[K12OSN] Error: Couldn't get the port at 378



I have a program that lets you enter a command like:

lptout 233

and it passes the number to the parallel port and sets the data lines high corresponding to the number you gave it.

The problem I am having is that when root runs the program, it runs fine.

When any other user runs it, it returns:

Error: Couldn't get the port at 378

like no one but root is allowed to use the parallel port.

Where would I look to fix this?

This same program works fine on every other computer I have tried it on but this particular one. . .

There are two files for it:

lptout and lptout.c

Thanks for any assistance.
