Hello all, I am having trouble getting asio serial ports to work.
Specifically when I call boost::asio::async_read, it immediately calls
the read completion handler with error EINVAL aka Invalid argument.
Please help! I have invested significant time in asio serial ports!
Mac OSX 10.6.4
GCC 4.2.1
boost version 1.44.0
The test case console output:
$ ./test
ERROR 22 Invalid argument
$
The test case code:
#include <iostream>
#include <cstdlib>
#include <vector>
#include <boost/asio.hpp>
#include <boost/bind.hpp>
const int HeaderSize = 2;
std::vector<char> ReadVector;
void ReadHandler(const boost::system::error_code& error, std::size_t bytes_transferred)
{
if (error)
{
std::cout << "ERROR " << error.value() << " " << error.category().message(error.value()) << std::endl;
return;
}
else
{
std::cout << "Bytes Received" << std::endl;
}
}
int main ()
{
ReadVector.resize(2000);
boost::asio::io_service SerialService;
boost::asio::serial_port SerialPort(SerialService, "/dev/tty.usbserial-FTCW1RJN");
boost::asio::serial_port_base::baud_rate baud_option(115200);
SerialPort.set_option(baud_option);
assert(SerialPort.is_open());
boost::asio::async_read(SerialPort, boost::asio::buffer(ReadVector, HeaderSize),
boost::bind(&ReadHandler,
boost::asio::placeholders::error,
boost::asio::placeholders::bytes_transferred));
SerialService.run();
}
