serial command to an HCR330 reader

[David]

Hello

My name's David and I begin to use CCS compiler with MPLAB.

I have a problem to send a serial command to a HCR330 smartcard reader.
The reader specifications are :
- 9600 baud rate
- 8 bits data length
- parity none
- 1 stop bit

I want to send the command "<ESC>E" and I made this little program ->


#if defined(__PCM__)
#include <16F877.h>
#fuses HS,NOWDT,NOPROTECT,NOLVP
#use delay(clock=20000000)
#use rs232(baud=9600, xmit=PIN_C6, rcv=PIN_C7) // Jumpers: 8 to 11, 7 to 1

#elif defined(__PCB__)
#include <16c56.h>
#fuses HS,NOWDT,NOPROTECT
#use delay(clock=20000000)
#use rs232(baud=9600, xmit=PIN_A3, rcv=PIN_A2) // Jumpers: 11 to 17, 12 to 18

#elif defined(__PCH__)
#include <18F452.h>
#fuses HS,NOWDT,NOPROTECT,NOLVP
#use delay(clock=20000000)
#use rs232(baud=9600, xmit=PIN_C6, rcv=PIN_C7) // Jumpers: 8 to 11, 7 to 12
#endif


void main() {

int a, b;

a = 0x1b
b = 0x45

printf(a, b)

}

I tried to set a and b in Dec like this a = 27 and b = 69 but It doesn't working too and I don't know why.

Have you an idea about that and can you help me ?

Thank you

Best regards

David
