thanks Russel,

i've done the test,

xdata unsigned char a,b,c,d,e;

a=1;
b=2;
c=3;
d=4;
e=5;

SBUF0 = a;
while (!TI_0);
TI_0 = 0;

SBUF0 = b;
while (!TI_0);
TI_0 = 0;

SBUF0 = c;
while (!TI_0);
TI_0 = 0;

SBUF0 = d;
while (!TI_0);
TI_0 = 0;

SBUF0 = e;
while (!TI_0);
TI_0 = 0;



I get all the values back.


It's really really strange.
