Well, I can't give you absolute certainty, but I suspect that the kernel support for serial consoles is here to stay. Part of the difference is the amount of code. The virtual console subsystem is a lot more complicated than the simple serial console used for boot messages, because it has to provide a full VT100 terminal emulator in kernelspace. On the other hand, the serial console doesn't have to emulate anything, since the thing on the other end of the cable is a real terminal of some sort. All it has to do is blast the kernel messages out the serial port. So the main difference is complexity. -- Chris _______________________________________________ Speakup mailing list Speakup@xxxxxxxxxxxxxxxxx http://linux-speakup.org/cgi-bin/mailman/listinfo/speakup
