Visual C++ to read Strings from Serial Port
Hi. I'm doing a project using Visual C++ to read data from Serial Port. My program needs to do *something* when it receives specific data. For eg, if the program receives "Alarm 1 Zone 4", it will do something. The data received will be variable in length. My questions: 1) Any recommendations for the serial Comm Class for Visual C++? 2) How can i compare the data i receive from serial to the specific messages i'm looking for, eg data types, size of data types, limitations & etc.? Thanks. Any comments are highly appreciated. Leng

As far as the serial part goes, it is pretty simple take a look at the CreateFile function. Here are some examples: http://www.codeproject.com/system/chaiyasit_t.asp http://www.naughter.com/serialport.html http://www.codeguru.com/Cpp/I-N/network/serialcommunications/article.php/c5425 As far as reading data from the port. Once you have opened the com port, you will need a worker thread the pulls the port for data. When you receive data you will be responsible to parse the data and interpret it's meaning. Without knowing how the data is being sent to you it's hard to make recommendations. AliR.

ajaykalrahttp://www.codeproject.com/system/cserialcom.asp will be helpful ........ secondly when u go to this lower level, u get only raw data ...... or are u expecting serialized data on port .... if yes then u may think of compatible deserialization .....
