8051 mode0 serial trans problem

[rameshrai]

hi,

i am trying to use the mode 0 serial transmission mode of 8051 microcontroller but it is not working.

what value of SCON register must be placed in order to use it?

i have used
scon = 0x00;

is this correct?

thanks

SCON=0x00 ok
for send data
TI=1;
SBUF=(data);
TI=1;
while(TI==0);
TI=0;
TI=0

the code is not working i only get the clock signal but not the data.

why there is TI=1 two times and TI =0 two times?

#include <reg51.h>

void main(void)
 { 
   SCON=0x00;
TI=1;
    while(1)
    {
SBUF=0x05;
TI=1;
while(TI==0);
TI=0;
TI=0;
}
   
 }

thanks
