I notice a talk about the crystal freq.

Im using a P89V51RB2 and RC2, and its not possible to change the Oscillator Frequency.
I`m running a 12mhz at this point and my comm doesn`t work.
it seems like im have a U coming in....i have to hook it up to hyper terminal to see if its a U.

Should I use a 11.0592Mhz crystal?

12MHz should work for autobauding at 9600 baud at least.
