Baud rate

Of course we know. But we also know that it isn't always possible - it depends on what hardware you have. But since _you_ know what hardware _you_ have, _you_ should be able to use Google to find how _you_ generate 57600 baud.

chek ur email. i sent ur q and handle to ansamewithspam.com so u can get one gud ansa.

u can thx me later.

I had microcontroller 89s52 and I have to interface finger print module SM630

It's irrelevant that you want to use a finger print module.

But have to tried Google? And have you considered that the used processor crystal makes a difference when computing baudrate?

Are you in the same class as Tarun Patel, then: www.8052.com/.../185441 ?
