Dear All,
AOA

I am trying to send the data from PC, MCU, And MCU to echo same data
But MCU is sending the data to PC, But when I send the command from PC to MCU, It Wont works....

About Code:
After starting MCU is sending 'L', And whatever PC send to MCU, I will ECHO. 4800 baud are being use by PC program. With No hand-shaking, I am using MSCOMM Control. Plz help to resolve the issue.



I think you need to skip the MSCOMM Control and use a terminal program to verify the operation of you uC program. As Jan suggested http://www.8052.com/forum/read.phtml?id=118748 try the examples in the RS232 guide.
