    Post DirecTV D2 card

    A new DirecTV card called D2, P6 or "rethink tv" by convenience, made it's
    first appearance sometime in Sept. 2005, but very little is yet public about it's
    technical data. Here a few card responses:

    The ATR of the D2 (0017 ...) is like that of a P4 or a D1

    ---------------------
    Trying to reset card...
    Reset Successful

    ATR: 3F 78 13 25 03 40 B0 20 FF FF 4A 50 00

    Convention: INVERSE
    Protocol: T=0
    TA1 = 13
    TB1 = 25
    TC1 = 03

    Historical Bytes: 40 B0 20 FF FF 4A 50 00
    @ J P

    Programming Voltage = 5.0 volts
    Programming Current = 50ma
    Maximum Clock Frequency = 5.0MHz

    Assuming a 3.5790MHz clock:
    Work ETU = 0.0000259849 seconds
    Guard Time = 0.0003897737 seconds
    Baud Rate After Reset = 38484
    ---------------------

    The INS 02, which gets us the ID and the ROM version

    ---------------------
    48 02 00 00 08
    R01
    R08
    R02
    ---------------------

    returns the following:

    ---------------------

    RX ATR : 3F 78 13 25 03 40 B0 20 FF FF 4A 50 00
    TX Data : 48 02 00 00 08
    RX Data : 02
    RX Data : 48 55 58 56 - 04 00 44 31
    H U X V - . . D 1
    RX Data : 90 00
    ---------------------

    An attempt to read 8 bytes from the beginning of the EEPROM
    ---------------------
    48 12 00 00 08
    R01
    R08
    R02
    ---------------------

    has this result:
    ---------------------
    RX ATR : 3F 78 13 25 03 40 B0 20 FF FF 4A 50 00
    TX Data : 48 12 00 00 08
    RX Data : 12
    RX Data : 78 FF 25 17 EF 19 05 15
    RX Data : 90 00
    ---------------------

    As it still has the "Before Returning from ATR Hole", we can get the ATR_DM:
    ---------------------
    33 99 FF BF E1 00 5B 17 08 67 5F 57 71 CF
    ---------------------

    inverted, according to ISO-7816, it looks like this:

    ---------------------
    33 66 00 02 78 FF 25 17 EF 19 05 15 71 0C
    ---------------------

    Bottom Line:

    Except for the result of INS 02, it looks pretty much like a D1, whose return value is
    ---------------------
    44 31 44 56 - 30 31 30 37
    D 1 D V - 0 1 0 7
