Hi Naomaru

Our driver for the ORGA ECO 5000 automatically sends GET_RESPONSE; if the
card returns '61 xx' or '9F xx' and the application passed a case 4 command
APDU to the reader. The class byte for GET_RESPONSE is copied from the class
byte used for the original command.

IMHO this is the way it should be done, because GET RESPONSE (as well as PUT
ENVELOPE) is a command of the T=0 transport layer and it should be invisible
for the application. The application should never really care whether a card
speaks T=0 or T=1. Unfortunately the designer of the PC/SC specification
didn't really follow this concept.

On the other hand there are (very old) cards out there, which may not work
because they require a different GET_RESPONSE. For such cases it might make
sense to disable automatic generation of GET RESPONSE.
