In the current 2.6.9rc3 patch flush_to_ldisc honours > TTY_DONT_FLIP also I've come late to this discussion. Not sure what the scope of this cleanup is, but I'd like to see the flip buffers done away with entirely, to be replaced by a single buffer with proper r/w locking. Or keep the flip arrangement, but move it out of tty_struct so that it can be made larger. Some of our high speed products find the rx buffer to be less than sufficient. ..Stu
