Question about used putty to login pc linux.

Hello all member.

it has been quite some time I use putty to log into linux machines from windows, when I need.
I have found my way through codepage problems, moving text files with different encoding across many different machines and OSes, and such.
But for keyboards... I have never seen the numeric keyboard work on this situation (windows+putty -> linux) and I trying to find out how.

What works:

- all keys on the main keyboard part and ESC
- insert, home, pg up, pg down, end and delete (on the center)
- arrow keys
- accented letters, cedilla and other exotics
- Alt Gr modifications (ABNT2 keyboard)

Does not work:

- turning on/off num lock (no apparent effect on the remote side)
- independently of num lock state, numeric keypad does not work

The behaviour is curious for some applications.

For example, what Vim (on remote machine) inserts as text when typing on the num keyboard is different from what appears on the login prompt initially. And if I do command ":sh" from Vim, I can type numbers naturally on the opened shell, differently. Why? How?

My goal is to find a way to change this behavior and have it fixed for my user. But fixing keyboard to work via win + putty may not break the keyboard when I log in with ssh from another linux machine, or log in the real machine.

I thought about variables like LANG or LOCALE, but for the keyboard.

thank's a lot!

Basically ssh will send stdin to the other side and there is no way to modify it on the remote site. I would say that is a host-local problem, I mean it should be solved on windows (+ putty). I cannot test it right now, but as far as I know it should work.

1. Check and report your terminal type when you use putty to connect to the linux machine.
2. Check and report your keyboard settings in your putty definition for that connection.
3. From the same connection, please report your codepage and window settings.

With a little information, we might be able to provide some advice.
