Uart using mode 3

Hellow

I have a project now, using Atmel's AT89C51RE2 as MCU.
I've already checked each UART(UART0, UART1) worked alone in mode 1, but I need 2 uarts works simultaneously.
I heard for both uarts working, each uart configuration has different baud rate, and different mode, is it correct?
anyway, I tried to make uart work in mode 3, but I failed.
Could you give me any advice ?? (or eg?)

thank you.

    Where did you hear it?

    Don't rely on hearsay - check it in the Datasheet!

    "for both uarts working, each uart configuration has different baud rate, and different mode, is it correct?"

    It's up to you to configure them how you want to!

    "I tried to make uart work in mode 3, but I failed."

    In what way, precisely, did you "fail"?

    "Could you give me any advice ?? "

    You need to describe the problem properly:

    What, exacly, did you try?
    What were you expecting to happen?
    What actually happened?
    What debugging have you done to account for the difference?
