This patch fixes a long standing problem with TTY's. The original code tried to workaround a limitation in the console of some embedded systems that was detrimental on actual TTYs. As an added benefit, the console specific "Press Enter" prompt for the console port is now available on all TTYs -- meaning no getty needs to be started and kept needlessly in the background until it is needed.
