[Helton M. <hm...@ya...>]

Hello Everybody

	I have a incoompreensive error, please tell me were stay the error:

The Code:

#include <at89x52.h>

// Global Variables =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
data unsigned char rx_buffer[16];
data unsigned char tx_buffer[16];
data unsigned char ptRx;
data unsigned char ptTx;
data unsigned char ptTxInsert;
bit RxDataFlg;

void Serial_ISR(void) interrupt 4 using 1
{
	ES =3D 0;
	if (RI){
		RI =3D 0;
		rx_buffer[ptRx++] =3D SBUF;
		if (ptRx >=3D 16) ptRx =3D 0;
		RxDataFlg =3D 1;
	}=09
	if (TI){
		TI =3D 0;
		SBUF =3D tx_buffer[ptTx++];
		if (ptTx >=3D 16) ptTx =3D 0;
	}
	ES =3D 1;

}

void putchar(unsigned char value)
{
	tx_buffer[ptTxInsert++] =3D value;
	if (ptTxInsert >=3D BUFFER_SIZE) ptTXInsert =3D 0;
	TI =3D 1:
}
void init()
{
	SCON =3D 0x50;
	TCON =3D 0x40;
	TMOD =3D 0x21;
	TR0 =3D 1;
	TR1 =3D 0;
	TH1 =3D 0xFD;	// 9600 bps to 11 MHz.
	TH0 =3D 0xDC;
	TL0 =3D 0;
	TR1 =3D 1;
	REN =3D 1;
	RI =3D 0;
	IP =3D 0;
	IE =3D 0x96;

	ptRx =3D 0;
	RxDataFlg =3D 0;
	ptTxInsert =3D 0;
}
void main (void)
{
	init();

	while(1)
	{
		if (RxDataFlg) {
			RxDataFlg =3D 0;
			putchar(12);
		}
=09
	}
}

// The result a infinit transmit to Serial Port (012-012-012-012...)
But i can't find the error...
Please Help Me !!!
Thanks
