using matlab API to send RS232 signals using a bafo usb-to-serial adapor

Hi,
I do not have a serial port on my laptop so I am using a Bafo
BF-810 serial adaptor (www.bafo.com) to send signals to a
microcontroller (2p40 from parallax). I am using matlab to send the
signals from my PC. Can anyone tell me how to write a Matlab API or
anything else in matlab to enable it communicate with the bafo
serial adaptor. My e-mail address is greenish_green@y...

    Just follow the directions *exactly* in the Appendix of the Matlab
    instruction book for writing to a RS232. If it doesn't work, the
    problem is in the adaptor, not the Matlab code.

    Hello (again) from Gregg C Levine
    RS232, is the name of the standard behind the term "serial port".
    Further, it explains in detail what travels on the 9 to 25 different
    pins, some non assigned, others assigned. Most PCs that still wear
    serial ports these days have only the basic DB9 connector, that's the
    AT configuration. Now where did you get your MATLAB kit from? They
    should be able to provide some documentation.

    Oy, what's a RS232?

    Your BAFO unit takes a USB signal, and makes
    it into Serial. The Serial standard it then uses
    is called RS232. In fact, your BAFO adapter
    'looks' like a serial (RS232) port to your computer.

    Thus, to interface with MATLAB, use the RS2332
    interface -- which your BAFO is now pretending to
    be.

    Matlab and the usb to rs232 adaptor (Bafo bf-810) with it drivers
    work fine. However, in order for me to use matlab to SEND OUT DATA
    and RECEIVE DATA through the adaptor and driver I must use API to
    make matlab and the driver communicate. I have no clue where to
    start in this regards.

    Since this list is for basicstamps, and The Mathworks has an excellent
    Matlab tech support structure, you should contact contact
    www.mathworks.com about this instead of this list.
