    im showing you a demo program done by be..recently for that with which i found some warning n errors.
    i.e. I can't go with the array data saving operation that should contain by SBUF register here.

    [CODE GENERATION]

    #include<reg52.h>

    #include<lcd.h>

    #include<serial.h>

    #include<string.h>

    sbit SW = P3^7;

    sbit motor1 = P2^0;

    unsigned char D[20];

    unsigned char i,value;

    bit flag;

    void Disp_Hex(unsigned char);

    void FINGER_FUN_IDT(); // finger identification

    void serial(void ) interrupt 4 {
    if (RI)
    { D[i] = SBUF;
    if (i>15){flag=1;}
    else i++;
    } }

    void main()
    { bit scan_flag;

    SConfig();
    scan_flag=0;motor1= 0;

    LCD_Init();
    LCD_Cmd(0x80);
    Disp_Str(" WELCOME ");
    Delay(50);clear();
    LCD_Cmd(0x80);

    if (SW==0) //scanning switch
    {

    FINGER_FUN_IDT(); //command identify function
    EA=1;ES=1;
    Delay(300);

    }

    if (flag==1)
    {

    flag=0;
