Frequently Asked Questions
==========================

- Why is the ATR not correct?

	The TLP protocol does not directly send back the ATR given by the
	smart card. The Tlp protocol always send the 4 bytes TA1, TB1, TC1,
	TD1. If one of these bytes is not send by the smart card the TLP
	protocol insert a 0x00 instead.


- What is the maximum response size?

	Due to TLP limitations, it is not possible to retrieve more than 252
	bytes from the card.


- Does the library support T=1 protocol

	No. Not yet. Only the T=0 protocol is supported.


- The device /dev/screader does not exists

	The library uses /dev/screader by default.

	The Debian configuration script uses debconf to ask you a question
	and create the file.
	If the script fails you can do
	$ dpkg-reconfigure libtlp
	to force a reconfiguration.

	If you do not have a Debian distribution you must create it by hand.
	$ cd /dev/ ; ln -s ttyS0 screader
	If your smartcard reader is not on ttyS0/COM1 you must use the
	right device (ttyS1, ttyS2, etc.).
