For the record... although 9600 baud, 8 bits and 1 stopbit is the default for serial lines, the default console is cga...

(too slow!) iirc, Good enough to play around and learn something new. I would like to turn it into an auth-only server booting from a fileserver, as indicated on [*]. More specifically, I wonder if this would be safe: on the one hand, an auth server actually shouldn't provide other services, on the other hand it would get everything via the network. Another thing to check would be the usage of a piece of a CF card as NVRAM.

Thanks for mentioning this as it caught my eye when re-reading the console part of the plan9.ini manpage. > - erik -- Frank Lenaerts ---------------------------------------- fr...@inua.be
