 * The "direct console" is an extremely simple console "driver" for PCs,
 * which writes directly to CGA/EGA/VGA display memory to output text,
 * and reads directly from the keyboard using polling to read characters.
 * The putchar and getchar routines are completely independent;
 * either can be used without the other.
