I would like to use Asio to connect to a microcontroller to send and read from, but there are no serial_port samples available.
For instance, I would like to type an ‘a’ into the keyboard and have the microcontroller return 1. The microcontroller is already programmed for this but I need to create an interface for it.
A sample that does this or any working sample at all would be sincerely appreciated.
Thank you,

Hi Jeff - Using the asio serial port is just like using the socket after you have one opened and going. To get things going: Construct the serial port with the associated io_service as with other ASIO services... asio::serial_port port( io_service ); Next, open the device and setup various options. I have found that the defaults among various OS's for the asio serial port differ. It can create real headaches so I initialize everything that I like: port.open( "/dev/ttyUSB0" ); // or whatever the device might be if( !port.is_open() ){ // do something clever if the open failed } typedef boost::asio::serial_port_base asio_serial; port.set_option( asio_serial::baud_rate( baud ) ); port.set_option( asio_serial::flow_control( asio_serial::flow_control::none ) ); port.set_option( asio_serial::parity( asio_serial::parity::none ) ); port.set_option( asio_serial::stop_bits( asio_serial::stop_bits::one ) ); port.set_option( asio_serial::character_size( 8 ) ); Then just use the port as you would a socket. For example, port.async_read_some( asio::buffer( in_message, MAX_MESSAGE_SIZE ), boost::bind( &my_client::read_done, shared_from_this(), asio::placeholders::error, asio::placeholders::bytes_transferred ) ); HTH, michael -- ---------------------------------- Michael Caisse Object Modeling Designs www.objectmodelingdesigns.com
