	Set the half-duplex UART bus in TX mode.
static void	uart_half_duplex_set_rx (uart_half_duplex_t *dev)
	Set the half-duplex UART bus in RX mode.
size_t	uart_half_duplex_send (const uart_half_duplex_t *dev, size_t size)
	Send the data contained in the driver's buffer.
size_t	uart_half_duplex_recv (const uart_half_duplex_t *dev, size_t size)
	Recv data an fill the driver's buffer.
