No, you need to invoke an open syscall just in the same way you did the
previous system call. Try looking at
http://goodfellas.shellcode.com.ar/docz/asm/aslenguage.html, which is a
tutorial for exactly this sort of thing.

You don't have to read or write to it; just opening it is enough to get
the I/O access you need.
