Awesome. Our first typing lesson here is "asdf ñlkj". I rarely login as root, prefer "su -c 'command arg'" than "su -". `sudo' is not even installed. Anyway, this root uses /bin/bash, but will change to /bin/sh for this experiment, I use rc(1). > Do you have problems with non-root login? - 'ñ' is echoed ok with /bin/sh for root and non-root logins, either with /bin/login and /lib/fgetty/login1 > Also, in my case problem is a bit another: > > - everything is perfect with non-root login > > - /bin/sh as root behaves good > > - /bin/bash (/bin/rc) behaves bad, and all its childs too. > > > > Also, let me ask you to check some of my wild guesses: > > > > > > - please, invoke `stty -a' in bad and good shells and tell, > > > if there is any difference. Yes: -isig vs. isig.
