Goggle for CreateFile/ReadFile/WriteFile/SetCommState.
mingw32ce supports open/read/write as simple wrappers around
CreateFile/ReadFile/WriteFile. You just have to realize that open returns
an int, which is really a HANDLE casted to int. In practice this means that
this is correct:
int fd;
if ((fd = open(...) == -1)
And this is wrong:
if ((fd = open(...) < 0)
