The device does not have modes like in unix. There are different
devices for each mode. /dev/ser0 is the lowest level and gives you
direct access to the serial driver. /dev/tty0 is the next level up and
gives you a basic tty level similar to cooked mode. Then there is
/dev/termios0 which is layed on top of /dev/tty0.
