backspace problem in cygwin

I want to use cygwin in windows XP, but there is a problem with backspace key
it doesn't work like backspace in windows (backspace removes character before cursor position)

what should i do to make backspace key work like in windows?

thank

Vim will use your terminals (cygwin in this case) defenition of erase, so the advice above is valid.
What value has erase? View it with
stty -a
at the bash prompt.
If you are unsure of what the backspace key generates, type
<ctrl>-<v><Backspace>
at the bash prompt.

You might also want to look at ":map"/":map!" .... ":help map" might be a start.

I had tried <ctrl>-<v><Backspace>, but it result is ^? (not ^h)
is it correct?
but it didn't solve the problem...


here is result from "stty -a": (maybe usefull)

$ stty -a
speed 38400 baud; rows 43; columns 125; line = 0;
intr = ^C; quit = ^\; erase = ^?; kill = ^U; eof = ^D; eol = <undef>; eol2 = <undef>; start = ^Q; stop = ^S; susp = ^Z;
rprnt = ^R; werase = ^W; lnext = ^V; flush = ^O; min = 1; time = 0;

Shows that your backspace key generates DEL (delete) instead of backspace (^h)
But since stty -a show that you have
> erase = ^?;
you _should_ be fine with this. In vim, the :map command could show what mappings are in effect. If ^? is interpreted as del, and not as backspace, this might explain your problems.
Do you have an .exrc or .vimrc file? Content? I'd suspect not, but there ($HOME/.vimrc) is perhaps where you should put the following
:set t_le=^?
(note that you need generate the DEL character with <Ctrl>-<v><your DEL/backspace key>, so that it is one character and not two as in <^><?>)

You can check the value of t_le in vim by the
:set termcap
command, and you can test that the line above works there too, before putting it in a .vimrc file.

great, It solved the probem, but it cannot remove the end of line

for example:
abcdefghij
klmnopq_  

(_ : cursor)
when I use backspace (at that cursor position), it removed klmnopq
but when i press backspace again, the cursor didn't move to upper line (after j character)

what should i do?

Read the docs:-) :help is there for you:-):-). ":help set" will show some, and also look at examples in /usr/share/vim/vim61/vimrc_example.vim (or similar).

Actually, to allow "backspacing" to delete lines you might add
set backspace=indent,eol,start
to your .vimrc file.
