    I am currently working on a project that need to convert some
    asynchronous and digital data from a serial port of a computer into
    synchronous RF data. In order to do this, I will need a buffer to
    store the digital data prior to process it. The buffer need to be
    larger than 1 kilobyte and has the capability to hard wire into the
    serial port to prevent buffer overflow/underflow. Please let me know
    where or how I can find a buffer like this. I have been looking
    several electronics distrubtor such as Digikey and Jameco and I was not
    able to find it. I will appreciate your help. Thank you.
  2. FAIK a component like this is not an of the shelf product. You'll have to
    build your own one. There have been days you'd use a stand alone UART with a
    Baudrate generator, a 1kB FIFO and some glue logic. It can still be done
    this way, but I doubt you to have the skills to design it. These days the
    way to go is using a micro with a build-in UART, a timer/counter to generate
    the correct Baudrate, over 1kB of RAM and the firmware to make it run. Alas,
    it requires some skills to design this too so I guess you'll have to learn
    about micros and their programming to make what you want.

    This is a job for a small computer. It could be done with a largeish
    microcontroller, but a single-board computer might be easier to work with.
    Or could the conversion be done by the computer that is outputting the data?
