i tried using X2 mode by configuring baud rate control register baud reload register pcon register clock control register
can anyone give the example for configuring the registers in x2 mode for baud rate of 115200
AT89c52 ,24MHZ clock speed
i stucked up in another problem tat im not able to receive data serially when i use max 485 bus thro hyperterminal .i have used convertor to convert rs232 to 485 in between the pc and my target board im not able to receive the data .can u guide me
