APDU [--atr] [--more] [--exlen[=n]] [hexstring]
Send an APDU to the current reader. This command bypasses the high level functions and sends the data directly to the card. hexstring is expected to be a proper APDU. If hexstring is not given no commands are send to the card; However the command will implicitly check whether the card is ready for use.
Using the option --atr
returns the ATR of the card as a status
message before any data like this:
S CARD-ATR 3BFA1300FF813180450031C173C00100009000B1
Using the option --more
handles the card status word MORE_DATA
(61xx) and concatenate all responses to one block.
Using the option --exlen
the returned APDU may use extended
length up to N bytes. If N is not given a default value is used
(currently 4096).
