Well, it has these points for it: - It works on all Linux platforms. - It supports arbitrary line speeds on those (few) platforms which integrate c_ispeed/c_ospeed in their termios structures (as opposed to having a separate termios2 structure.) - It has a real chance of doing so on the other platforms, too, as soon as glibc integrates full c_ispeed/c_ospeed support for them. I think we can't do any better right now.

We tried, didn't we? If you see any way of integrating the termios2 stuff so that compiles on all platforms, I'll gladly take it. I wouldn't even insist on the "cleanly" requirement. Thanks, Tilman
