Initial function

1) Init_com(sett:pchar):integer

 Function：Initial serial port

 Return：Integer

     =    1：Success

          0：Communication failed。

         -1：Port is being occupied。

         -3：Invalid configuration 。

 parameter：

    sett: text  array,(to set the serial port).

       format:"1,9600,N,8,1" ------ (1=com1 or 2=com2),

                                   (9600=baud9600 OR 4800=baud4800

                                   OR 2400=baud2400 OR 1200=baud1200),

                                   Parity : (N=None or O=odd or E=Even ),

                                            (8= 8 bits 7= 7 bits),

                                            (1=1 stop bit OR 2=2 stop bits).

       Ie.:"2,9600,O,7,1: " COM2, Baud rate 9600. Odd ,7 data bits,1 stop bit.”

Close serial port：

2)  close_com

  function：Close the opened port by “Init_com” function.

  Return：None

  Parameter：none

Operating functions

Function Link:integer;

 function: control communication .

Rerun: Integer

   = 1: Success communication

     -1: Can't open the selected COM port

     -2: Communication failure (not connected or not connected properly)

     -3: Port setting error.

parameter：none

_reset:integer;

function:Reset.

Return: Integer

   = -1: Can't open the selected COM port

     -2: Communication failure (not connected or not connected properly)

     -3: Port setting error.

parameter：none

W_card(wdata:pchar):integer;

Function:  encode

Return: Integer

   =  1: Write successfully

     -1: Can't open the selected COM port

     -2: Communication failure (not connected or not connected properly)

     -3: Port setting error.

     -4: Encoding error

Parameter:

 wdata : text array, (data to be encoded).

  format:"%xxxxxxxxxxxxxx?"        ------  write track 1（x=data）

             ";xxxxxxxxxxxxxx?"     ------  write track 2（x=data）

             "+xxxxxxxxxxxxxx?"     ------  write track 3（x=data）

             "%xxxxx?;xxxxxxx?"     ------  write track 1,2（x=data）

             ";xxxxx?+xxxxxxx?"     ------  write track 2,3（x=data）

             "%xxxxx?;xxxxxxx?+xxxxxx?"     write track 1,2,3（x=data）

             1: track 1 = 76 alphanumeric characters

             2: track 2 = 37 numeric characters

             3: track 3 = 104 numeric characters

       ie.:   W_card("%1111111111?")

                        -------- write：1111111111 into track 1

             W_card(";2222222222?")

                        -------- write：2222222222 into track 2

             W_card("+3333333333?")

                        -------- write：3333333333 into track 3

             W_card("%2222222222?;1111111111?")

                        -------- write：2222222222 into track 2 AND

                                     write：1111111111 into track 1

             W_card(";2222222222?+3333333333?")

                        -------- write：2222222222 into track 2 AND

                                    write：3333333333 into track 3

             W_card("%1111111111?;2222222222?+3333333333?")

                        -------- write：1111111111 into track 1 AND

                               write：2222222222 into track 2 AND

                                     write：3333333333 into track 3

 R_card(rdata:pchar;track:integer):integer;

Function: decode.

Return: Integer

   = -1: Decoded successfully,

     -2: Can't open the selected COM port

     -3: Communication failure (not connected or not connected properly)

     -4: Port setting error.

     -5: Reading error

Parameter:

 track: selecting tracks

            --------  1： select track 1

                       2：select track 2

                       3：select track 3

                       4：select track 1&2

                       5：select track 2&3

                       6：select track 1,2,&3

 rdata: Decode Data Output Buffer（to store the returned data of every successful read）

         Text arrays, > 300 Bytes.

Format of a successful read:

    rdata = "%xxxxxxx?"       ------- return track 1 data（while track=1）

    rdata = ";xxxxxxx?"           ------- return track 2 data（while track=2）

    rdata = "+xxxxxxx?"           ------- return track 3 data（while track=3）

    rdata = "%xxxxxxx?;xxxxxxx?"   ------- return track 1&2 data（while track=4）

    rdata = ";xxxxxxx?+xxxxxxx?"   ------- return track 2&3 data（while track=5）

rdata = "%xxxxxxx?;xxxxxxx?+xxxxxxx?"  return track 1&2&3 data（while track=6）

     track 1 = 76 alphanumeric characters

     track 2 = 37 numeric characters

     track 3 = 104 numeric characters

     ie.：

             R_card(rdata,1)

                       -------- read data from track 1（stored in rdata）

             R_card(rdata,2)

                       -------- read data from track 2（stored in rdata）

                       -------- read data from track 3（stored in rdata）

             R_card(rdata,4)

                       -------- read data from track 1&2（stored in rdata）

             R_card(rdata,5)

                       -------- read data from track 2&3（stored in rdata）

             R_card(rdata,6)

                       -------- read data from track 1,2,&3（stored in rdata）
