#79256 - A Problem at Receiver End
Responding to: ???'s previous message
Hello Everybody,

For simulation I have connected two 8051s (TXD -> RXD)and receiving a 3 bytes of data. But at the receiver the first byte is duplicated. i.e. If I send XYZ the receiver gets XXYZ. (I am using ISIS 6 professional for it)

Both microcontrollers have same frequencies and baud rate.

the code at receiver is

unsigned char data receivedData[3] = {'*','*','*'};
unsigned int data rIndex = 0;

void getData(void) interrupt 4 using 1
{
	if (RI)
	{
		receivedData[rIndex] = SBUF;
		RI = 0;
		rIndex++;
		if ( rIndex == 3 ) rIndex = 0;
	}
}

But if I poll there is NO problem. Please help me solve this...
