I need a basic example for sending AT commands to mobile. This will require serial communication on COM port. If any one can send me any example of it.. I want to do this using BOOST. By searching on GOOGLE I got this but this is not compiling. #include <iostream> #include <boost/asio.hpp> #include <boost/asio/serial_port.hpp> #include <boost/thread.hpp> #include <boost/system/error_code.hpp> #include <boost/system/system_error.hpp> #include <boost/bind.hpp> void handler(const boost::system::error_code& error) { std::cout << "read" << std::endl; } int main(int argc, char* argv[]) { using namespace std; using namespace boost; char read_msg_[512]; boost::asio::io_service io; asio::serial_port theport(io,"COM7"); theport.async_read_some(boost::asio::buffer(read_msg_),handler); io.run(); return 0; } Thank You Rahul To create something exceptional ________________________________ -Master4Master "Confidentiality Warning: This message and any attachments are intended only for the use of the intended recipient(s), are confidential, and may be privileged.
