Unix driver for Towitoko smartcard readers
Copyright (C) 1998 1999 2000 2001 Carlos Prados <cprados@yahoo.com>

This library provides a driver for using Towitoko smartcard readers
under UNIX environment.

Smartcard API's provided:
=========================

* CT-API 1.1 and CT-BCS 0.9. See ctapi (3) and ctbcs (3) man pages
  provided with this package.
* PCSC Lite. See http://www.linuxnet.com for download and
  documentation.

Supported readers:
==================

* Towitoko Chipdrive Micro, Extern, Extern II, Intern, and Twin.
* The most recent readers labelled as "Kartenzwerg" use
  the same protocol as Chipdrive, and should work with this driver,
  although they have not been tested.

Supported interfaces:
=====================

* Serial readers: Configure you serial port like for a modem. See
  http://www.linuxdoc.org/HOWTO/Serial-HOWTO.html
* USB readers: Linux kernel version 2.4.12 or greater with PL2303 USB 
  serial driver enabled is needed. 
  See http://www.linux-usb.org/USB-guide/book1.html
  Note that PL2303 support is still in experimental stage! 
  Also note that pl2303.c drivers from kernel versions previous to 2.4.12 
  will surely not work with this driver and will probably hang your machine.

Supported smartcards:
=====================

* Processor cards: direct and inverse convention cards, T=0 and T=1
  protocols. Short and extended case 1, 2, 3, 4 ISO 7816-3 APDU's. PPS and 
  baudrate selection from 9600 bps to 115200 bps.
* Memory cards: I2C, 2 wire and 3 wire bus protocol. Access to memory
  cards is provided via the Interindustry Commands described in the
  MCT v09 part 7 spec. See
  http://www.panstruga.de/ct-api/spec/spec_v09.html

Installation:
=============

See the file INSTALL.

Special `configure` options:
============================

--enable-debug(=1|2|3|4)
  Debug level 1,2 and 3 prints debug information to stdout. Debug level 4
  prints debug information to syslog.

--enable-card-type(=sync|async)
--enable-card-convention(=dir|inv)
--enable-memory-type(=i2cs|i2cl|2w|3w)
  "sync" is for memory cards and "async" for processor cards. "inv"
  is for inverse convention cards and "dir" for direct convention.
  "i2cl" is for I2C cards with up to 16 kbits of  memory, "i2cl" for
  I2C cards with up to 64 kbits of memory, 2w for 2 wire cards, and
  3w for 3 wire cards. Enabling one option prevents the driver from
  doing auto-detection.

--enable-memory-size(=size)
  By default memory size is set to 8192 bytes. If 0 length is
  specified the driver will perform probing of memory size. Otherwise
  the specified value will be used.

--enable-ISO-t0
  Transportation of APDUs by T=0. With T=0 cards this will enable the driver 
  to automatically handle T=0 transaction control TPDUs following ISO 7816-4 
  Annex A normative.

--with-pcsc-lite-dir
  PCSC Lite base directory (default=/usr/local/pcsc). USB bundle is
  installed under $pcsc_lite_dir/drivers if USB bundle support is enabled.

--enable-usb-bundle
  enable USB bundle installation (default=no).

--enable-devfs
  enable Linux 2.4.X devfs support (default=no).

--enable-devpcsc
  enable /dev/pcsc links support (default=no). Serial devices will be searched
  at /dev/pcsc/1, /dev/pcsc/2, etc. You will have to create links to the actual
  serial devices.

--enable-win32-com
  enable win32 style COM port numbering (default=no). Port numbers under CT-API
  will start with 1 for COM1, 2 for COM2 and so on.

--enable-thread-mutex
  enable thread mutexes (default=yes). Needed for multi-threaded
  applications.

--enable-atr-check
  enable checking of valid ATR (default=yes).

--enable-atr-timings
  enable decoding of timings from ATR (default=yes).

Configuration:
==============

To configure a serial reader in PCSC Lite, copy the provided file
doc/reader.conf to /etc/reader.conf and modify it to match your serial
port settings. No configuration is needed for USB readers.
