Generating 38400 or 115200 Baud Rate using AT89C52 Microcontroller

Dear All,
               I am Ravikmar.N, working on  Atmel (AT89C52)
microcontroller.

I know that TIMER1 of AT89C52 can be used to generate  baudrate upto
57600.

I need to set the microcontroller  to 38400 or 115200. I dont know what
values to be filled to the TIMERn register and which TIMERn to be used.


If anybody know the solution please share your knowledge with me.


Thanks in advance.
