Hi all,

I've started to do some work on my 8052 board again, does anybody know a good starting point where I can learn how to make my program output to be sent to serial device?
I have some tutorials with my reads51 software where I can do some output to the serial line:

#include <cSio51.h>
main(){

// --- initialize serial port (9600 Baud) ---
InitSerialPort0(DEF_SIO_MODE); //DEF_SIO_MODE is defined in <sio51.h>
cprintf("test");
while(1);
}
//--- end

And here's the .h file
-------
#ifndef __SIO51_H
#define __SIO51_H

// prototypes
void PrtDec(int n);
void PrtHex(unsigned int u);
void putc(char c);
void puts(char *sz);
char getc(void);
void printf(char *sz);
void InitSerialPort0(int nMode);

#define _9600_11_059_TIMER1 0
#define _9600_24_TIMER1 1
#define _9600_12_80535BRG 2
#define _9600_10_C515BRG 3

// global definition of serial mode
#define DEF_SIO_MODE _9600_11_059_TIMER1

// macros to access the function argument stack in assembly
#define DPTRAST mov a, BPL \
add a, #0xFA \
mov dpl, a \
mov a, BPH \
addc a, #0xFF \
mov dph, a

#define DECDPTR xch a, dpl \
jnz $+4 \
dec dph \
dec a \
xch a, dpl

#endif
-------
If I try to compile the same program using different tools I'm getting errors, I believe this is because main 8052.h file(which is not known to me) is included by default, would anyone have any suggestions on that at all?
Cheers
Tomas
