    Exclamation NMEA Decoding?

    I want to ask if some one have decode the NMEA standard signal generated by the GPS receiver, using microcontroller(preferable) or the serial port with his own software?
    If someone do this thing, please send me the details and the steps to do this brililiant thing.

    Question

    Yea, i have read about the NMEA, but still there are some questions.
    One of them, 4800 baud per second, how much the baud is? and is the "no parity" bit sent or not?

    Try it with hyperterminal first and see.

    Create a new connection, specify the port, speed,settings = 4800, 8, N, 1 (or something like that.. )

    Save it, Hit connect. You should start seeing the GPS/NEMA sentences flying by...

    Thanks for the reply....
    I did the same as you mentioned, but i couldnot see the NMEA messages but could see only some junk data of symbols..
    I even tried with the TSIPMonitor32.exe, but could not get the data in it. Please help me with steps, how to use TSIPMonitor.exe.I even gone through the Lassen LP Manual.
    The manual is explained according to the starter kit. but I m not using Starter kit instead I interfaced Lassen LP module to PC serially through Max232.
    waiting for the reply..
