I am not sure actually. I just open /dev/ttyn0 and /dev/ttyn1 and write to one, and read from the other. I didn't even know about the line diciplines actually. How do I tell which one I am using?
ioctl(TIOCSETD/TIOCGETD) sets/returns an integer identifier that can be compared agains the N_XXX macros. If you are not explicitly setting this then is is probably the default N_TTY. Also at the application level, look at tcsetattr() for setting the termios features. Look specifically at the c_cc[VTIME] and c_cc[VMIN] members of the termios structure. These settings control how much data must be available before returning data to a read(). Try VTIME=0 and VMIN=1. Since your 'missing' data is always on the tail end, maybe VMIN is set to 64 or something. -- Paul Fulghum Microgate Systems, Ltd. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
