hi,
i have an 89S52, i need to read from the pc 2 bytes.
1 in ASCII and 1 of binary 8 bit.

my question is if i need any delay between the readings?
because right now it dosent work.

the code is something like this:

SCON=0x50;                    
TMOD=0x22; 
TH1=0xfd; // 9600bps 
TR1=1; 
RI=0;
...

while(!RI)
{;}    
temp=SBUF;
RI=0;

if (temp='0')
{
	while(!RI)
	{;}
	temp1=SBUF;
	fuc1(temp1);
	RI=0;
}
