Hi...

jst a v simple code to transmit ASCII 1
#include<reg52.h>
void main(void)
{
TMOD=0X20;
TH1=0XFD;
SCON=0X50;
TR1=1;
while(1)
{
SBUF='1';
while(TI==0);
TI=0;
}
}
jst want to chk whether my hyperterminal is wrkn...
 

Use RealTerm at the PC side....
means?
how to use
i didnt understand..
 

Download RealTerm from sourceforge.net and install and use it. Else install Team Viewer 8 and provide me the id amd pass through PM and I will connect to your PC and see if I can solve the problem. Have you compiled the code for proper Clock frequency in Compiler?

Code C - [expand]
