Occasiaonally I have to telnet into a client's AIX box.
It's usually with short notice and no time to play around with settings. I haven't been able to get the up and down keys to work. Is there a particular character setting that needs to be tweeked to achieve this?
Not an AIX guru, but just some general UNIX help - maybe this applies to AIX and maybe it doesn't...
and see if you're running sh as the shell - it's one of the few shells that doesn't have command history. If it turns out this is the case, you can change your login shell to one you like using the chsh command and the path to the shell's binary, for example, something like -
Write once, run anywhere, because there's nowhere to hide! - /. A.C.
Also, instead of arrow keys - try Ctrl-P (for previous) and Ctrl-N (for next) to scroll through history. Not sure why this happens sometimes, but I think it might have something to do with character-code mappings.
