(I believe the answer is no! I got half way through writing a pty/tty replacement driver which passed the relevant ioctls (decoded into platform independent "change baud rate to 9600" etc) on the tty in-band to the pty. I used in-band so this data stream could then be piped via ssh etc) -- Nick Craig-Wood ncw1@axis.demon.co.uk - 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/ | ||||||||||||
