Dear adatapost ,

Thanks for your advice and support .

The problem is that I do not know what to do , what I have done is the following :
1- I made a vb.net program that opens the serial port communication COM port .
2- I tried to send command to the device , eg to make it stop logging , as per the NMEA communication protocol of the MTK Logger ( as per the pdf file in the initial post) , but unfortunataly , nothing happens . I amy be wrong ,
3- the question , when I developped the program that send the command to the device , which command I should send , eg , as pe rthe pdf file , the following command will stop the unit to log ($PMTK182,5*) . but , it still send data.
4- There is a program which is done at the end of the pdf file which describe a sample program , but done in C++ , unfortuneatly , I do not understand how compile it it .

The Question is how to start , what i did wrong , and is the command i sent is the right command .

Thank you in advance for your support.
