It doesn't do anything special. but for some reason there seemed to be people who did now want to loose the first character, so i was wondering if the entire first character could be bitbanged in gpio mode and put into the sw buffer for the serial port, which would be reinserted into the foodchain after the completion of the first character. Of course in the case of human input it would probably mean that all the characters could be bitbanged, if the timeout for entering low power states is short enough, but wouldn't that be very close to reality where, like in the internet tablets, the serial port is disabled in production mode? What we usually see is that during development as soon as we enable production mode (iow no active serial port, not even with timeout) those drivers which were relying on it to provide some sort of wakeup, fail. Just a thought. -- Cheers, Igor --- Igor Stoppa Maemo Software - Nokia Devices R&D - Helsinki -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
