Could you briefly elaborate on how that's done with 7.x? I.e. is changing device.hints and /etc/ttys enough (what changes?), or do I need to recompile the kernel? (I'm a bit confused because both uart and sio seem to be in GENERIC, but I haven't been able to active uart through device.hints. I couldn't find anything on freebsd.org or the internets, either.) A few hints would be much appreciated! -- Cheers =8-} Mike Friede, Völkerverständigung und überhaupt blabla
