Screen + Vim + NumPad

[ardan mon]

Hello,

I am having problems with vim when I use screen.

I can't use the num pad , 

When I press the '/'  in the numpad keyword vim show up  'o'
and a new line, when I press  with '*'  an 'j' and  with
the '+'  shows a 'K' .

In a normal terminal without screen the numpad works. 

Can someone helpme to configure screen properly?

Thanks.
