I want to communicate at89c51 to computer so i am using rs232.
As i am new to this communication please help me that what i have to do for communication and can anyone give simple example program to just send simple message or data from controller to pc.
Also i need one information that if i have to program each for transmit and receive than how i have to dump it into controller. i mean in single hex file or how?
