C8051F060?

 tried to use c0851F060's UART0,but I found there is no output signal
from tx0 and rx0(I using crossbar to mapping tx0 rx0 to P_0,P_1),I
don't know why?,so can anyone remind me that any passable wrong I colud



make?


p.s my internal oscillator is 24.5Mhz,how can I create baud rate 9600?
thanks for gave me advice friends,I still confuse,so I repost this
problem.My program as below:


#include <c8051f060.h>                    // SFR declarations

p.s my internal oscillator is 24.5Mhz,how can I create baud rate 9600?
thanks for gave me advice friends,I still confuse,so I repost this

Tthanks for helping me configuration baud rate 9600,please tell me why
my Tx won't 
output? I will very appreciate you ~

Dear Bob~
Can you give me a sample cord for C8051F060 UART0?
I tried several times...UART0 still can't word.
please help me~
