"proc does not exist yet" - the only time that applies is long before userspace as active. As I've said already, having a console on the same port as your application program is just asking for trouble. All bets are off - the kernel _will_ corrupt your data stream in random places. Don't do it - it will _NEVER_ be reliable. Never, ever, mix kernel consoles with application serial ports.
Ok. I understand now one of the sources of misunderstanding. I don't want to mix console and application serial port. It was a question, Myke Frisinger initially asked. I would switch on/off console depending on some external control action if possible... The other problem is how to open serial port with correct settings _after_ booting. In this case /proc could be applicable, isn't it? -Oleksiy - 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
