That would make sense. Lee's error is a hardware FIFO overrun which could occur if the FIFO is being disabled as described in your link (by trying to set the uart type with setserial). Since the tty flow control is only triggered by the line discipline in response to ldisc buffer levels and not hardware FIFO overruns, you would never see any flow control action as reported by Lee. -- Paul Fulghum Microgate Systems, Ltd. - To unsubscribe from this list: send the line "unsubscribe linux-serial" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
