According to ISO, the protocol must be negotiated immediately following
reset, and remains in effect until the next reset.  You can't change the
protocol without a reset.

        I have a general question about multiprotocol smartcards (e.g.G&D
test
        card)

        After a cold reset I select T=0.
        Now I want to select T=1 protocol without a reset.
        Is that possible ? What should the driver return ?

        I think the behaviour should be the same if I first select T=1 and
T=0
        without a reset.Correct?

        Best regards
        Thomas
