6.1.19.
CCID_ESC_GET_SET_TA1_RFU
Since the reader is compliant to ISO 7816-3 (1997), it will reject cards having a TA1 value
which is RFU in respect to this version of the specification. Using this escape function the
application can introduce such a card to the reader. If a card having this particular value of TA1
in the ATR is detected, it will be accepted by the reader and the maximum communication
speed (i.e. 115200 bps) will be applied. The buffer shall point to the escape code followed by a
BYTE.
