International character POS Display

Hie everyone,

I have a problem with an HP POS USB Pole Display LD220 (FK225AT) Firmware 15.00.60.

I can switch between Codepage without problem (from CP437 to CP1252) with the HP USB Line Display Configuration Utility ver 6.0.3.7 but I canot change the international chacrter set from english to any other like French and like this have access to charters lilke éàöüäôîâ.

Is ther a special tool for doing this or how do we send the right command directly to the Pole with a software like Putty?

Thanks in advance

Fabrice
