    Smart card baud rate question

      Dear all,
      I have a question about smart card baud rate:

      - What Does F/D value indicated in the ATR in the negotiable mode show?
      Does it show the max F/D value? As you know according to the following formula, as much as the F/D value gets greater, the transmission rate gets smaller:
      baud rate = f / (F/D)
      So if the F/D value in the negotiable mode is the max value, the transmission rate will be kind of the min value?!!!
      I,ve got confused in this problem, please help me!
