I have a microcontroller connected to the COM2 port on a Windows machine, and want my Haskell program to interact with it. My Haskell program is working nicely on my Mac, with interaction using stdin and stdout, but I am not familiar with Windows and a quick Google search did not give me any information on how to get Haskell IO happening through a Windows serial port.
* How should I open the COM2 port? IO Mode? Buffering?
* How do I write and read?
I presume I can set the port parameters fusing something like:
...; e <- system "MODE COM2 19200,*,N,1,P"; ...
You can also set these default parameters somewhere in the Control Panel. In case the openFile function is implemented under Windows by calling "CreateFile" in the Windows API, then you can just call openFile with the name "COM2:19200,8,N,1,P" or simliar and use standard read and write functions on files. Maybe this helps, Axel.
