Functions
void	TTY_outchar (char byte)
	writes one character to the current console tty. More...
void	TTY_setcontty (int whichtty)
	selects the console TTY TTY =0 is the SCI interface TTY =1 is the DUART channel A TTY =1 is the DUART channel B. More...
void	TTY_conecho_on ()
	enables echo of input characters on the console tty. More...
void	TTY_conecho_off ()
	disables echo of input characters on the console tty. More...
int	TTY_setbps (struct TTY_tty_dev *tty, int bps)
	sets the connection speed on tty to bps. More...
void	TTY_setmode (struct TTY_tty_dev *tty, char mode)
	Sets tty into mode. More...
char	TTY_getmode (struct TTY_tty_dev *tty)
	returns the current mode of tty. More...
char	TTY_getstate (struct TTY_tty_dev *tty)
	returns the current state of tty. More...
char	TTY_readchar (struct TTY_tty_dev *tty)
	reads one character of tty. More...
void	TTY_writechar (struct TTY_tty_dev *tty, char byte)
	writes one character to tty. More...
char	TTY_inchar (void)
	reads one character from the current console The function returns the character read. In nonblocking mode, it returns a 0 if there is no character in the queue. More...
void	TTY_soutchar (char byte)
	writes one character to the current console tty without blocking interrupts This function should be used with caution, it is usefull to print from an ISR. More...
void	dummy ()
void	TTY_init (void)
	initializes all TTYs in the system. This function is normally called from the crt0.s startup file. More...
Variables
