Number keypad in vim insert mode [8]

I'm using the number keypad with num lock on in insert mode in vim. The number keypad inserts letters on a new line. The letters that are inserted are below. When not in insert mode, the number keypad work as expected and enters numbers. Does anyone have a solution to get the number keypad working normally in insert mode?

1=q
2=r
3=s
4=t

Program Ver. : Xshell 4

I should say that with SecureCRT the keypad functions normally entering numbers in insert mode on the same machine

This is due to different terminal type setting. You can change the Terminal type in Xshell session properties > Terminal. Set it as ansi and number pad should work in VIM.

Filipe - Thank you so much!@!

Exactly correct.

When I change to ansi mode, it seems PgUp and PgDn does not work well in the normal mode of vim. It will act as a function to change the current letter to a capital style instead of scroll the screen.

In VIM (or VI), the following keys are used to move between pages:

Ctrl-F - forward one page
Ctrl-B - back one page

None of the above worked well enough for me. Switching to ANSI meant loosing the functionality of other keys - namely my delete becoming a backspace (no, I didn't have "delete sends backspace" checked - though I tried checking it to see if it would fix it!) Other keys weren't working either, like home/end, etc. So I started playing. Here's what worked best for me in SecureCRT:

Under Terminal -> Emulation:
1) Set Terminal to XTerm (optionally turn on ANSI color, works fine for me.)
2) Make sure alternate keyboard emulation is unchecked.

Under Terminal -> Emulation -> Modes:
1) Make sure "Numeric Keypad" is selected in both sections.
2) Uncheck "Enable keypad mode switching".

Restart SecureCRT and give it a whirl. The only problem you might have is if you turn numlock off, the numpad does strange things (does not operate as arrows.) I don't mind this - I never turn numlock off... Also, if it makes a difference, I'm connecting to my dev machine, running Ubuntu 12 server 99% of the time... I ssh to other servers from there, and the numpad continues to work as expected on other machines I connect to.

Thank a lot. That solved my problem.

In xshell:
Terminal→ VT modes:
Initial Numeric Keypad Mode (DECNKM) - Set to normal.
With NumLock - numbers, without NumLock - arrows.
