Read to an array from serial port and a can baud rate calculation

[Magvitron]

Hi, I am building a CAN n/w using pic 18f25k80. Can any one help in the following
1. Calculating the baud rate of CAN
my current setting

//Setup the Baud Rate @16 Mhz.
    BRGCON1 = 0xc3;
    BRGCON2 = 0x9e;
    BRGCON3 = 0x03;

2. How to read from the UART to an array
my current code (this is not working) ie there is no update in array.

/**************************
Initialize the serial port
@ 160000 and 230400bps
***************************
Requires :none
Returns : none
**************************/
void uart_init()
{//Enables Serial port  
/*RCSTA RECIEVER CONTROL REGISTER*/  
RCSTA1bits.SPEN = 1;
RCSTA1bits.RX9=0;//8 bit reception
RCSTA1bits.CREN = 1; //enable the reciever

  TRISCbits.TRISC7=0;
  TRISCbits.TRISC6=0;
/*TXSTAx: TRANSMIT STATUS AND CONTROL REGISTER */
TXSTA1bits.BRGH=1;//baud rate high bits    
TXSTA1bits.SYNC=0;//assynchronous mode      
TXSTA1bits.TX9=0; //8 bit reception
TXSTA1bits.TRMT=1;//reset the buffer
TXSTA1bits.CSRC=0;// Master mode  (clock generated internally from BRG)
/*BAUDCONx: BAUD RATE CONTROL REGISTER*/
BAUDCON1bits.BRG16=1;//16 bit Baud rate is enabled

SPBRGH1 = 0;
SPBRG1 = 16;//2;
//(((_XTAL_FREQ/baud)/4)-1);
//FCY/64)/BAUD) - 1;
// set baud to 9600  FCY=20000000
//Turn On the Tx and Rx
TXSTA1bits.TXEN=1;
RCSTA1bits.CREN=1;
}

  count=count+1;
  uart_num(count);
  if (count>63)
  break;
 
}
uart_string("out of here");
rxr[count]='\0';
count=0;
}

char uart_read()
{
while(!RC1IF);
RC1IF=0;
return RCREG1;
//RCSTA1bits.CREN = 0;
//RCSTA1bits.CREN = 1;

}

can any one point out how to do it?

P.S. I'm using XC8 compiler basic.
