    hello am doing a project SMS/GPS Vehicle tracking

    system, i am using a philips 8051 microcontroller (XA-

    G49), to be programned in c language, a garmin 18X-LVC

    gprs receiver, and a Cinterion MC55i Terminal Quad Band

    (GSM Module)
    I have connected the micro controller to the gsm module

    via rs232 male-male cable, and also took the white wire

    from the gprs receiver which i connected to pin 1.4 on

    the micro controller. i keep sending the request from

    the main operator my phone and have done every thing i

    think is right with the code, but still get no

    response.
    Please could any one give a hint on how to go about

    this whole issue perhaps i may be doing some thing

    wrong with the connection or the choice of my

    apparatus may be wrong.
    Please any possible hint would help a lot

    humm well are both GPS and GSM working separately with your code. are they working with computers serial port.
    baud rate of both modules should be same.
