If the kernel is asked to do CRTSCTS then the kernel handles the flow control. It uses it when the internal buffers are nearly full.
The direct access to the lines is normally only used by special drivers such as half duplex radio modem drivers. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
