Did some more research, and when i tested the program again with the external devise connected, i got this. trace:file:GetOverlappedResult wait on 0x40c8ccc0 returned 0 trace:comm:SetCommMask handle 96, mask 1 trace:comm:WaitCommEvent (60 0x415a6f18 0x40c8ccc0 ) trace:file:GetOverlappedResult (96 0x40c8ccc0 0x415a6f18 1) trace:file:GetOverlappedResult waiting on 0x40c8ccc0 trace:comm:COMM_WaitCommEventService overlapped 0x40c8ccc0 wait complete 0x415a6f18 <- 1 this repeats over and over again, this is not to far from my previus results, but here there should be something happening on the com port. in ms windows there is no problem even withouth anything connected to the comm port, it just sends requests infinitly to the device witch is not there, and it does not hang. But in my case the program hangs on the linux box, now i can understand that, but why is it not getting communication from the comm port, it seams to be configured right, and there should be something there to read. Is the support for overlapped IO in wine not good enough yet, or lies the problem somwhere else?
