I think I know more about these problem.
TA2 is 0x81, So it's Specific mode and have the ability to change mode through
hot reset.
But, Fi Di != Fd Dd, so even if changed to Negotiate mode, the PTS command
won't be accepted still.
And because TA2's bit5=0, so the Fi=9 and Di=5 will be used.
In summary, the T=1 has been selected automatically after reset and use Fi,
Di(no more
Fd,Dd). So I needn't do anything after reset. Just send SELECT FILE command.

Yes, that's right. It's used in our set-top box(STB).
I just try to do some base firmware tests now. And may be added supports under
OpenCT later.
I changed a card and readed out the ATR:
TS: 3f T0: ff TA1:95 TB1:00 TC1: ff TD1: 91 TA2: 81 TD2:71 TA3:a0 TB3:47 TC3:00
History: 44 4e 41 53 50 30 20 54 65 73 74 30 33
So, It should be a nagravision card , and there may be some unknow problems in
the former card i used.
But I got a new problem.
The TD1 in the ATR is 0x91, so only protocol T=1 is supported.
And TA1 is 0x95, that means Fi=9, Di=5,not Fd=Dd=1 any more.
And TA2 is 0x81, means that it's Specific mode.and it's bit5=0.
Then whether I needed sending PTS to select protocol T=1 after receiving ATR ?
If needed, how to send it ?
Because "ISO7816 3.4 Protocol type selection (PTS) " said "If only one
protocol type and FI=D=1 (default value of TA1) and N smaller than 255 is
indicated in the answer to reset. The transmission protocol associated to the
protocol type may be started immediately after the transmission of answer to
reset. "
So, I can't send PTS because Fi=9 and Di=5, and N=0xff.
If not, the following operations such as SELECT FILE use which F and D(Fi, Di
or Fd, Dd) ?
I did'not found clear answers in ISO7916-3 about these things. May be I shoule
read it once more.

A ha, You have a good sense of humor. But sometimes it's no choice.
It's so long, thank you for your time.
