Hi, Short version: backspace problem is already solved in ksh93.
Long version: I performed some tests with various combinations of ksh versions and terminals and found that apparently, the problem with the backspace key not erasing the character left of the cursor IS ALREADY SOLVED in ksh93 r+ and s-. This does not mean that other applications would not be remapping the backspace function, as Alan mentioned. When just using the shell, and making sure that no "stty erase" is in /etc/profile, /etc/ksh.kshrc, ~/.profile, or ~/.kshrc (or whatever ENV is set to), I found that the backspace key is not correctly mapped to the backspace function ONLY in ksh version 11/16/88i (the current version in Solaris). I also found that "stty" in xterm or dtterm shows that "stty erase" is already set to ^h by default. For gnome-term, this is not the case (= there is no "stty erase" entry shown). Apparently, ksh93 is already able to deal with all this. I found that an stty erase ^h entry was in /etc/profile during previous tests, which caused a different behavior of ksh93 and apparently made be believe that the problem is still there.
