I am new to 89S51 proramming. I am using "Keil" to programm this chip.
I want to interface it with PC. I have developed a utility in "C" which send commands and receives reply from PC's serial port. Now I want to connect 89S51 at serial port. I don't know how to use 89S51 chip's Rx and Tx pins and configure it's interrupt register.
Can somebody sugget me or refer a link.
