What I don't understand is why you changed: tty00 to ttyd0 but: cua00 to cuaa0 ??? What's wrong with "ttya0" or "cuad0"? > When did they make sense? They were never called sio* or ttys*.

Along with the broken programs that assume the ttyXX pattern. > >For 2.1, can we go back to at least making the tty and cua devices have the > >same identifiers? > When did they have the same identifiers? If you say that tty00 and cua00 > have the same identifiers, then I'll say that `0' is not an identifier :-). Oh, don't be silly. You know what I mean. "00" and "00" for COM1 make sense. "d0" and "d0" make less sense, but still work. "d0" and "a0" are just plain weird. > That would be bogus. X works with the vanilla POSIX port ttyd0 and > always has. Fine. Then the XFree86 setup needs to use that instead of /dev/mouse. You're looking at it from the point of view of someone who knows what all this stuff does. I'm dealing with someone who doesn't and wants to learn, and only comes to me when something's broke. That's good. That's the sort of people we want to encourage. All this inconsistency makes it harder.
