Yeah, 250kbaud, that's crazy fast. The 8051 is not capable of running at such high baud rates. Do you think if I clocked the controller at a lower frequency, I can decrease the baud rate to that frequency? Like Decreasing the clock speed to 19200Hz to get data at 19200baud, which the micro can handle.

Hey. I need to interface the PSX controller to the 8051 microcontroller. I got alot of info about the controller from
http://www.gamesx.com/controldata/psxcont/psxcont.htm
Does anyone know what the baud rate for the "Command" and "Data" lines of the PSX controllers is?
Thanks.
