(Sorta back on topic: 'screen') How to fix backspace/delete key in OS/X (Mac)

1.(Somewhat OT) How to fix backspace/delete key in OS/X (Mac)

Yes, this is OT, but it is also a FAQ here.  People having problems with
their backspace key(s).

Anyway, recently started using OS/X on a MacBook.  Use ssh from 'Terminal' to
connect to shell account.  When I hit "delete", it generates: [3~
Now, note that I am well aware of solutions involving "stty erase ...",
but that's not optimal.  The right way to fix this sort of thing is to
fix what character the key sends, not to kludge the remote system to
accept whatever the key currently sends.

Note also that the key generates the right code (127) when hit locally,
but for some reason is translated when sent to ssh.

Has anyone else solved this problem?

2.backspace and delete keys using SSH

I'm having an annoying problem using F-Secure SSH on an AIX 4.3.3
machine.
When logged in via SSH the backspace key doesn't erase the character
shown on screen, it just backspaces over the top, even though AIX
recognises that the character HAS been deleted.  (NB this all works
fine via telnet.)

It doesn't seem to make any difference whether I set the emulator so
that Backspace sends Delete or vice versa, and nothing I have tried
using "stty erase" seems to help either!

I think this may to do with the SSH client rather than AIX tbh, but
does anyone have any idea how to fix it?

Many thanks

David

3.backspace and delete key mappings

I have read much on the subject of these 2 keys. Yet I have not been
able to do what I need to do. I need the backspace key to generate
0x08(^H)  and the delete key to generate 0x7f(del) during the execution
of a single  application. On all my linux boxes the backspace generates
0x7f(^?) and the del key generates  ^[[3~. I need to be able to change
that before I execute my program then change it back when my
application is done.  stty does NOT do the job nor does my application
use termdef. I have found a little expect script that does do what I
need. I execute "script program" and the keys come out like I want.

#!/usr/bin/expect

eval spawn -noecho $argv

interact {
 \177        {send "\010"}
 "\033\[3~"  {send "\177"}

However I am really looking for basic Linux commands that can be
executed from the bash shell that will do the same thing or a method of
making my application do it from within its self.

Thanks and regards

5.'/' become backspace and backspace key insert '~'

I ssh to a solaris 10 computer from a FC6 computer.
The keyboard behave properly when login as root:

root# stty
speed 38400 baud; -parity
rows = 23; columns = 80; ypixels = 0; xpixels = 0;
eol =  eol2 =  swtch < ;
brkint -inpck -istrip icrnl -ixon onlcr tab3
echo echoe echok echoctl echoke iexten

The keyboard behave improperly when login as non-root:
The '/' key acts as the backspace key.
The backspace key insert '~'.
-bash-3.00$ stty
speed 38400 baud; -parity
rows = 23; columns = 84; ypixels = 0; xpixels = 0;
erase = /; eol = ; eol2 = ; swtch < ;
brkint -inpck -istrip icrnl -ixon imaxbel onlcr tab3
echo echoe echok echoctl echoke iexten

$ bash -version
GNU bash, version 3.00.16(1)-release (sparc-sun-solaris2.10)

Please help to fix it.
Thanks.
