I can't delete characters using the backspace key，and the tab key cannot be used for auto-completion;

Does this have anything to do with the fact that my remote connection session is on an aix system

The report concerns backspace and Tab behavior in a remote session on AIX, but names no source file or test. Start by reproducing both key behaviors against an AIX session and determine whether the terminal client or remote environment controls them; done means the responsible scope and expected behavior are documented.
