1. INTRODUCTION

This manual describes the use of ACSR20 interface software to program the ACR20 &

ACR30 smart card readers. It is a set of library functions implemented for the application

programmers to operate the ACR20 & ACR30 smart card readers and the inserted smart

cards. It can be programmed using the popular development tools like Visual C/C++, Borland

C/C++, Visual Basic, Delphi, FoxPro, etc…

Depending on the reader model, ACR20 & ACR30 series of smart card readers can be

connected to the PC via the RS/232 interface or USB interface. The connecting interfaces of

different model of readers are summarized as follow:

Model Numbers Connecting interface

ACR20S, ACR20S-S, ACR30S, ACR30S-S

Serial RS/232

ACR20U,ACR20U-S, ACR30U, ACR20S-S

USB interface

Even though the hardware communication interface can be different, application programs

can still be using the same API (Application Programming Interface) for operating the smart

card readers. Actually, the purpose of using the ACSR20 library is to provide the programmer

with a simple and consistent interface over all possible hardware. It is the responsibility of the

ACSR20 library to handle the communication details, parameter conversions and error

handling. The architecture of the ACSR20 library can be visualized as the following diagram:

2. ACSR20

2.1 Overview

ACSR20 is a set of high level functions provided for the application software to use. It

provides a consistent application programming interface (ACSR20 API) for the application to

operate on the card reader and the corresponding inserted card. ACSR20 communicates with

the ACR10/ACR20 reader via the communication port facilities provided by the operating

system. ACSR20 is supposed to be platform independent provided that there is a minor

modification on the communication module of the ACSR20 to adapt to different operating

environment.

2.2 Communication Speed

The ACSR20 library controls the communication speed between the reader and the PC. For

those readers using the serial RS232 connection, the default communication baud rate

(factory setting) is 9600bps, no parity, eight bits and one stop bits. A higher speed of

115200bps can be achieved by using software command issuing from the host. If you are not

sure about the factory setting of your readers, you can always use the ACR_AUTODETECT

option in your AC_Open command for the driver to detect the communication speed

automatically. Please notice that the above communication speed setting apply only on those

readers using the RS232 connection. For the PS/2 type and the USB type of connection, the

speed is fixed at 9600bps and 1.5Mbps respectively.

2.3 ACSR20 API

The ACSR20 Application Programming Interface (API) defines a common way of accessing

the ACR10/ACR20 reader. Application programs invoke ACSR20 through the interface

functions and perform operations on the inserted card through the using of ACI commands.

The header file ACSR20.H is available for the program developer which contains all the

function prototypes and macros described below.

2.3.1 Interface Data Structure

The ACSR20 API makes use of several data structures to pass parameters between

application programs and the library driver. These data structures are defined in the header

file ACSR20.H and they are discussed below:

BYTE P1;

BYTE P2;

INT16 Lc;

INT16 Le;

BYTE DataIn[256];

BYTE DataOut[256];

WORD16 Status;

} AC_APDU;

The AC_APDU data structure is used in the AC_ExchangeAPDU function for the passing of

commands and data information into the smart card. For memory card operation, please refer

to section 0for the definition of fields’ value. For MCU card (T=0,T=1) operation, these value

are specific to the smart card operating system. You must have the card reference manual

before you can perform any valid operations on the card. Please notice that Lc representing

the data length going into the card and Le representing the data length expecting from the

card.

BYTE HistLen; // Length of the Historical data

BYTE HistOffset; // Offset of the Historical data

// from the beginning of ATR

INT16 APDULenMax; // Max. APDU supported

} AC_SESSION;

The AC_SESSION data structure is used in the AC_StartSession function call for the retrieval

of ATR information from the smart card. Before calling AC_StartSession, the program needs

Smart Card Reader Driver Program Reference Manual rev 1.1 Sept, 2003

2.3.2 Interface Function Prototypes

Generally, a program is required to call AC_Open first to obtain a handle. The handle is

required for subsequent calls to AC_StartSession, AC_ExchangeAPDU, AC_EndSession and

AC_Close. The inserted card can be powered up by using the AC_StartSession function and

card commands can be exchanged with the inserted card using the AC_ExchangeAPDU

function. Moreover, AC_SetOptions and AC_GetInfo are two commands that can be used to

set and read the various information of the reader.

2.3.2.1 AC_Open

This function opens a port and returns a valid reader handle for the application program.

Format:

INT16 AC_DECL AC_Open (INT16 ReaderType, INT16 ReaderPort);

Remarks:

1. If the user select ACR_AUTODETECT to open a reader in the first time, the library will try to reset the reader

and wait for the response message from the reader. This may take some time (around 2-3 seconds) for the

library to complete this operation.

2. When an ACR20 is reset, the green LED will flash three times. There is no reset for an ACR10 reader.

3. When the application want to access the security module, it needs to open (use the AC_Open command) the

reader for the second time to get a different handler for the handling of the security module session.

4. The option of AC_USB is available only in the Windows 98 and Windows 2000 platform.

The option of AC_PCSC is available only in the platform with the Microsoft PCSC base components installed.

The driver will select the first available PCSC reader for operation. In order for the correct operation of the

reader, you need to make sure that the first available PCSC reader is a smart card reader from ACS.
