As I mentioned, I don't know how it works.  But consider:

The keypad is in application mode.  I want to type in numbers.  It 
fails. Why?  Seems to me as if different characters are being sent. 
Note, I can be running WEENDOZE and for example be in NOTEPAD and I 
still don't get numeric characters.  Sure seems to me to be in the device.
