Uuuh, I would be against software delays for the same reason why we don't accept software based direction switching: No guarantees. msleep() might easily delay longer than what was requested. Or are delay_rts values to be interpreted as "delay at least"? Regards, Wolfram -- Pengutronix e.K. | Wolfram Sang | Industrial Linux Solutions | http://www.pengutronix.de/ |
