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,

    yes its a project idea, we decide this idea!!!
    ...what is better each item send or the total purcahse??
    ...by the way, we will assume the cost of each item by using a data base !! is this a good idea , if isn't what is the best???

    being still a student, you have the privilege to make mistakes. that's fine. but once you get your degree and start working, you will need to plan carefully what you are going to do before starting any kind of implementation. That is called collecting requirements (part of software development cycle), and is of extreme importance when working on almost any software project, let alone embedded systems that often involve moving parts or mission critical code.
