How to change the period-sign at the numeric keypad to a comma
 

Hello Linux supporters,
I have a numerical keypad problem to solve:

I would like to change the period-sign at the numeric
keypad to a comma. This must work in the terminal emulation program putty.

In the console i can acomplish this by using the following commands:
dumpkeys > file.txt
And than chang entry in file.txt 83 = KP_Period becomes KP_Comma.
Than using the command loadkeys file.txt
This works fine in the console environment, but i need it to work in putty so in a terminal on a windows box.

Who can help me fix this difficult problem?

Thanks in advance!
Best Regards,
