I want to send and receive some informationa between the AT89S8252 and my pc with the serial port. I tried some examples like this one:

http://www.keil.com/support/docs/1653.htm

but it didn't work, then I tried their boudrade calculator and the boudrade that the set in the program, was too high, and I changed it to 900, but it still didn't work.
when I reset the AT89S8252, I receive some strange characters, but then nothing happens, if I send characters from the pc, again nothing happens.

can anybody help me using the UART in keil C?

thanks in advance,
