2input serial port with 8051

I have a problem with interfacing two serial port with 8051 microcontroller. I have to use bar code reader and RF reciver and transmitter which both of them interfaced serially. I am thinking to add an ic to controller these to serial ports, but I don't know which type of IC I should used!!
could any one help me, please?

Thanks,

I guess you still need to use 2 MAX232 devices, as RS232 is a point to point type not a multi drop!
