+Restart the current connection; this is a kind of warm reset.  It
+deletes the context used by this connection but does not actually
+reset the card.

+@subsection Send a verbatim APDU to the card.
+
+@example
+  APDU [--atr] [--more] [@var{hexstring}]
+@end example
+
+
+Send an APDU to the current reader.  This command bypasses the high
+level functions and sends the data directly to the card.
+@var{hexstring} is expected to be a proper APDU.  If @var{hexstring} is
+not given no commands are send to the card; However the command will
+implictly check whether the card is ready for use.
+
+Using the option @code{--atr} returns the ATR of the card as a status
+message before any data like this:
+@example
+     S CARD-ATR 3BFA1300FF813180450031C173C00100009000B1
+@end example
+
+Using the option @code{--more} handles the card status word MORE_DATA
+(61xx) and concatenate all reponses to one block.
