How to bind (shift Fx) for emacs in putty?

[c.c]

Hi,

I am in a putty terminal, I can bind the fx to some function for emacs,
such as (global-set-key [f1] "hello world!"), but if I bind the (shift
Fx) like this (global-set-key [(shift f1)] "hello world!"), I will be
failed! And the "C-h k" can get correct key description for the (shift
f1).

Any suggestion?

Thanks.
