I recently bought a atmel 89s51 based development board . but I did not get any uart program ..
the development board has all required Rs232 ckt , now I need to just need a sample program which can receive a input from pc and send data to pc via uart ..
Actually that development board localy made , it is not from atmel or any other standard company .
So I need uart sample program for 89s51 .. so that I can try that prgram ..
