EXAMPLES
	"i" is used to send information to the card:
		the following command sends a "select" APDU for a 
		file 3f 00 (DF):
		     you  type-> ic 00 a4 00 00 02
		     output   -> Enter 2 data bytes (hex):

		     you  type-> 3f 00
	     positive response-> 90 00 ok
	     negative response-> 6a 82 file not found
	     negative response-> scwrite failed
	"o" is used to get information from the card:
		the following command sends a "get response" APDU
		for 8 bytes:
		     you  type-> oc 00 c0 00 00 08
	     positive response-> 1:ff 2:ff 3:ff 4:ff 5:ff 6:ff 7:ff 8:ff 
				 90 00 ok
	     negative response-> 6d 00 unknown instruction
	     negative response-> scread failed
