<Delete> key do not erase char in insert mode with putty on HP
PoWah Wong
The <Delete> key do not erase a single char in insert mode. Instead it change the char from upper case to lower case or vice versa.
How to fix this?
I read
"Mapping keys in Vim - Tutorial"
http://vim.wikia.com/wiki/Mapping_keys_in_Vim_-_Tutorial_%28Part_1%29
but still do not know what to do.

First, check what gets inserted when you type, in insert mode:
CTRL-V<Delete>
It looks like your terminal may be sending something like <ESC>~,
which would show up as ^[~ after you do the above, causing Vim to
leave insert mode (<esc>) and toggle the case of the character under
the cursor (~).
There are a few ways to fix this; one of them is to :set <Del>=(type,
CTRL-V<Del> as above).
There may, of course, be better ways to do this.

I guess you aren't using the proper $TERM value for your terminal.
Here, with 'term' set to xterm, the Delete key is supposed to be ^[[3~
which, if sent in Insert mode and not interpreted, would go to Normal
mode, beep, and toggle one character from upper to lower case or vice-versa.
Method I. Find the right value for $TERM and set it in putty before
starting Vim. Try xterm or xterm-color for a start.
Method II. :let &t_kD = "\e[3~"
(the latter won't "repair" the other wrong key definitions you might have).

Tony.

CTRL-V<Delete>
displays
^[[3~
Then what should I do?
This does not work:
:set <Del>=[[3

See :help :set-termcap
I think you want:
set <del>=(press CTRL-V)(press delete)
But maybe it needs to be <t_kD> instead of <del>...see Tony's post.
I haven't had trouble with any keys except for the alt key before.

It should work in Console Vim. For gvim you need a properly set X-server
which can display on your machine and be accessed by a gvim running,
presumably, on the remote computer.

That should be
:set t_kD=^[[3~
where the ^[ means <Esc>. The easiest way to insert that sequence
after the = is to type Ctrl-v Delete as you did above. See
:help termcap
As someone else wrote, this is really a symptom of a larger
problem--that the terminfo database that vim is using is not
matching the terminal that you are using--that is likely to bite you
again if you don't fix it properly.

Are you sure you're using Vim? ":help" is a pretty basic command, and
pretty ancient too -- I'd say that it's fundamental to Bram's software
philosophy. Now if you aren't using Bram's software but the "original"
vi or some other clone of it... then I guess we can't help you.

Maybe you've already figured this out, but you shouldn't use the &
option prefix with the set command. Use the & prefix only with the
let command. So either of these will work:
:set t_kD=^[[3~
:let &t_kD="\e[3~"
where ^[ is a literal escape character. Note, too, that escapes
such as \e will not work in a set command.

Did you use a very slow terminal? Does increase timeout solve your problem?

I downloaded and installed the latest vim, so I am using vim 7.1 on HP.
This problem is intermittent (bill lam's email suggested that timeout may be the cause).
Another question is that the <Backspace> key behave like a "normal" <Delete> key.
i.e. Pressing the <Backspace> key erase the current char.
How to change its behavior to "erase the char before the current char"?

>> How to increase timeout?
pls see
:h timeout
specifically, first check yr current setting
:set to? ttimeout? tm? ttm?
then try
:set timeout timeoutlen=3000 ttimeoutlen=3000
there will be 3 second delay, if this cure the problem then try
other or smaller values.

Maybe ":help :fixdel" could help you.

where "^V" is CTRL-V and "<BS>" is the backspace key.
It works partially.
The backspace key works only until the <Esc> key is pressed. Afterwards only the new characters just typed can be erased.
The existing characters cannot be erased,
The cursor either cannot move or move over the existing characters .

:help 'backspace'
You want at least
:set bs=start
and probably
:set bs=indent,start
Personally, the eol flag drives me crazy so I don't use it, but you
might like that behavior as well.

It wasn't very clear to me just what the problem was, so I took a
guess and apparently guessed wrong. You wrote,
The backspace key works only until the <Esc> key is pressed.
which I took to mean that the backspace works in insert mode until
you press <Esc> to enter normal mode. Then you wrote,
Afterwards only the new characters just typed can be erased.
In normal mode, you should be able to delete any characters equally
well, whether or not they were just entered, so I assumed that you
entered insert mode again to type those new characters. Being able
to backspace over only the characters typed since entering insert
mode and not over any characters typed previously is symptomatic of
the 'backspace' option not having "start", so that is the solution I
offered.
If that's not the problem, then it would help my understanding to
know exactly what you typed, what you expected to happen and exactly
what did happen instead.

Gary

My goal is pressing [<---] (i.e. the backspace-key on my keyboard) will erase the char to the left of the current cursor.
The problem is that in both insert or normal mode,
pressing [<---] will
erase the char under the cursor.
~/.vimrc is:
set timeout timeoutlen=3000 ttimeoutlen=3000
:if &term == "xterm"
: set t_kb=^?
: fixdel
:endif
"set backspace=indent,eol,start
"set backspace=indent,start
"set bs=indent,eol,start
set bs=indent,start

That's strange, in normal mode <BS> should move cursor left (same as h), by
default it should not erase any character.
Under insert mode, does ctrl-h correctly delete the character on the left?
You mentioned you use putty, will it be possible that putty does not emulate an
xterm perfectly? Can you test with another software instead of putty? Did you
know anyone who has a positive experience of using vim with putty? disclaimer:
I have never used putty before.
That ttimeoutlen=3000 will cause 3 second delay, it will not be comfortable. At
any rate, that seems unable to solve your problem either.

I tried another program Tera Term VT to ssh to HP from windows, but have the same problem.
I used putty to ssh to linux from windows and do not have any problems with the keyboard mapping, so I think the problem is with the HP machine which I ssh to. However I cannot upgrade its OS.

Could you or ask someone else physically access the hp directly, and to verify
vim does run correctly on that machine?

It does not need a mouse. press alt-ctrl-f1 to alt-ctrl-f6 to login
again. However since x-window is not running, try running vim
without x server. eg,
vim - X
