C++ (Cpp) set_control_lines Examples

Example #1

File: tty.c Project: mikeberkelaar/grhardened

static int
ipw_tiocmset(struct tty_struct *linux_tty, struct file *file,
	     unsigned int set, unsigned int clear)
{
	struct ipw_tty *tty = linux_tty->driver_data;
	/* FIXME: Exactly how is the tty object locked here .. */

	if (!tty)
		return -ENODEV;

	if (!atomic_read(&tty->open_count))
		return -EINVAL;

	return set_control_lines(tty, set, clear);
}

Example #2

File: f81232.c Project: sombree/Hulk-Kernel-V2

static void f81232_dtr_rts(struct usb_serial_port *port, int on)
{
	struct f81232_private *priv = usb_get_serial_port_data(port);
	unsigned long flags;
	u8 control;

	spin_lock_irqsave(&priv->lock, flags);
	/* Change DTR and RTS */
	if (on)
		priv->line_control |= (CONTROL_DTR | CONTROL_RTS);
	else
		priv->line_control &= ~(CONTROL_DTR | CONTROL_RTS);
	control = priv->line_control;
	spin_unlock_irqrestore(&priv->lock, flags);
	set_control_lines(port->serial->dev, control);
