I have just configured ttyO2 in the system configuration, so that inittab has it there and I can login. Afterwards I can specify a password and the next time I login I also get a password prompt. What kernel are you using? Best regards, Yegor Am 19.07.2012 18:32, schrieb Charles Krinke: > Thanks for the encouragement, Julian.
