That seems to do it.
Just mknod tty c 5 0 in the /dev directory, and then it work.
The image has tty0 thru tty6, and the process uses tty1 thru tty4 
in the inittab. That is how it was when I took over the project, and had no info 
on the setup, and had to figure out how to build new kernels. 
But question is? If using /dev/tty1 as the current terminal, why would /dev/tty 
make a difference? 

Have updated the build system, and will make the addition in the next build.

Thanks again.
