| Hi, Jason. I don't know how to mark the call unsafe. And I don't know what is a *Nix (perhaps unix?). I am running the main program on Windows. Here is the compilation script: ghc -fglasgow-exts serial.c %1.hs -L./ -ljapi --make erase *.hi erase *.o strip %1.exe BTW I figure out that passing an argument to closecport only makes the problem occur less often. Here is an example: D:\ghc\sensors>strip temper.exe D:\ghc\sensors>temper.exe 4 D:\ghc\sensors>temper.exe 4 D:\ghc\sensors>temper.exe 4 D:\ghc\sensors>temper.exe 4 D:\ghc\sensors>temper.exe 4 D:\ghc\sensors>temper.exe 4 D:\ghc\sensors>temper.exe 4 D:\ghc\sensors>temper.exe 4 D:\ghc\sensors>temper.exe 4 D:\ghc\sensors>temper.exe 4 D:\ghc\sensors>temper.exe 4 D:\ghc\sensors>temper.exe 4 D:\ghc\sensors>temper.exe 4 D:\ghc\sensors>temper.exe 4 D:\ghc\sensors>temper.exe 4 D:\ghc\sensors>temper.exe 4 D:\ghc\sensors>temper.exe 4 D:\ghc\sensors>temper.exe 4 D:\ghc\sensors>temper.exe 4 D:\ghc\sensors>temper.exe 4 D:\ghc\sensors>temper.exe 4 D:\ghc\sensors>temper.exe 4 D:\ghc\sensors>temper.exe 4 D:\ghc\se nsors>temper.exe 4 D:\ghc\sensors>temper.exe 4 D:\ghc\sensors>temper.exe 4 D:\ghc\sensors>temper.exe 4 D:\ghc\sensors>temper.exe 4 D:\ghc\sensors>temper.exe unable to set comport cfg settings 4 --- On Mon, 11/9/09, Jason Dusek <jason.dusek@gmail.com> wrote:
