Is there a good way to access the serial port using
mingw since is does not have the termios functions?
I've tried using some Windows code (CreateFile,
BuildCommDBC, and WriteFile). That compiles and links
without any warnings but always crashes on execution
with a invalid page fault in Kernel32.dll. Listed
below are the main lines for I used for opening the
port.
char *SerPort = "com1";
HANDLE Comm;
DCB dcb;
COMMTIMEOUTS cto = {0};
Comm = CreateFile(SerPort, GENERIC_READ |
GENERIC_WRITE, 0, 0, OPEN_EXISTING, 0, 0);
cto.ReadTotalTimeoutConstant = 500;
SetCommTimeouts(Comm, &cto);
FillMemory(&dcb, sizeof(dcb), 0);
dcb.DCBlength = sizeof(dcb);
BuildCommDCB("19200,n,8,1", &dcb);

Hi, since I decided to use Dev-C++ as my primary IDE, I feel I must join this MingW-users mail list. Hello, everybody! Is there a good solution in mingw that operate serial communication port? I searched out some C/C++ libraries, but they only mentioned VC++ / Borland C++ compiler, I think I must ask here for any experiences from mingw users. How do you access serial port? What library is your favorite? Or even pure win32 api? For non-blocking (event driven) programming, pure win32 api must has many work to do. Am I right? Thanks!

If the library comes with source code included, and it builds fine with MSVC++ and Borland, it should build fine with MinGW too. Probably you will need to create the Makefile (or whatever Dev-C++ uses) for MinGW, if the library does not comes with one included, but most of the time this is an easy task. > How do you access serial port?

If you don't have a trusty library at hand and you are comfortable with the Win32 API and the serial device you need to manage has a precise and fixed communication specifications, the Win32 API is possibly as good choice as locating, learning and verifying a C/C++ library. -- Oscar |

Yes, it's source code. It need multi-thread support enabled by the compiler, how can I enable that in mingw? And all you ever accessed serial port in mingw is win32 api? If the library comes with source code included, and it builds fine with MSVC++ and Borland, it should build fine with MinGW too.

To use threads with Mingw, compile and link all of your objects = (including libraries) with the "-mthreads" option to gcc. Yes, I have only used the Win32 API to access serial ports, though with = MSVC not Mingw (but there is no difference). I noticed that the Common = C++ library (http://sourceforge.net/projects/cplusplus/) has = platform-independent classes for multithreaded serial I/O and lots more.

If you can find C/C++ libraries for MSVC or Borland that are open = source, they should compile with Mingw without too much trouble (unless = of course they require MFC or something like that). You may already know = that you can usually use MSVC static libraries or DLLs with Mingw if = they are written in C, but not C++. When looking for open source = libraries, you should also search for cross-platform libraries (e.g. on = SourceForge). If a suitable library is not available, the Win32 API would be the next = option. Using overlapped I/O is not too difficult if you need = non-blocking serial I/O. I don't know about event-driven programming, = but multithreading is another option worth considering.

http://www.iftools.com/ This library is basically a wrapper for the serial port API (and some timer stuff) that can be used on both win32 and linux. It is intended for wxWindows, but it works fine with out it.
