This is so not the right mailing list. Come on, are we playing hide and seek here? You can use strace to follow a typical hello world example and see what device it opens to feed the hello out. I.e. it can be to the current /dev/ttyX and not to /dev/console or if you are logged in via SSH to a machine, the device is again different... or if you use screen, ... Work your way from there and then use a Linux Source code Cross Reference (lxr, ask Google for one) and follow the code.
