 How to switch b/w UARTS in C8051F120

Hi frnds,
I am using C8051F120, where I want to switch between 2 UARTS, Plz let me know how can we program to switch over two UARTS when it is needed? can we use common Timer1 as for Baudrate genration??

Each UART has its own set of SFRs - so you just pick the appropriate set!

if( use_uart_1 )
{
   // Use the SFRs for UART1
}
else
{
   // Use the SFRs for UART2
}

"can we use common Timer1 as for Baudrate genration??"

The Datasheet will tell you that!

 explanation needed

presumably UART0 is connected to device a and UART1 is connected to device b.

so you feed UART0 with data for device a and feed UART1 with data for device b

whare is a switch in that picture??
