When a card returns 61.xx, it means that the card has xx byte to
return to host. 

Does a smartcard reader driver handle this, usually?  Does it
automatically send get_response APDU and get the return data, or does
it pass the status code 61.xx to the application? 

I am not trying to find out which the right way is.  I am trying to
find out how the actual reader drivers do it.

Thank you.
