Client Putty Xshell Connect with vim in Linux does not work properly with the keypad

When using Vi/vim on Putty or Xshell, press the number key on the keypad when you open NumLock and you cannot enter a number, but instead appear a letter and then wrap it (in fact, the key that corresponds to the top or bottom of the command mode).

Workaround:

Putty: Option Terminal->features, find disable application keypad mode, choose on it.

Xshell: The terminal Type in Properties->terminal in the connected session is modified to Linux or ANSI to use the keypad normally.
