    I have a UART program written on ARM processor ......I am getting the output at 115200 bps .....But i want to check the output at 1250000...whereas the hyperterminal or anyother terminal programs support upto max 921600bps......Can anyone provide me with a solution or can i get any tool which supports 1250000bps baud rate......

    I'm guessing that you'll be hard pressed to make the components go that fast. Remember that a UART typically uses a x16 clock to sample the received data. The physical layer components used in RS-232 communication may also be running out of gas at that speed. I think you're SOL.
