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.
At the application level you do not have to deal with PTS and
communication speed. It is the job of the card reader or of the card
reader driver.
I think that Bob said that he was writing a driver, so maybe he means
that
he is writing a driver for a reader that communicates at the byte level?
