Returned handle cannot be used with "isatty"

Well, this is pretty complicated I think.
In Linux when you initialize a communication with a serial device using the open() function and it returns to you a file descriptor (which is an integer), while in Windows the handler is stored in a HANDLE type variable, which is actually a void pointer.
Because of this, I don't think you coulduse the HANDLE of the COM structure to pass that control.
If I were you I'd check if it is possible to skip that check.

I currently have ignored the check for windows.

In general the MSVC docs also have this function basically: https://msdn.microsoft.com/de-de/library/f4s0ddew.aspx and I found somewhere that it uses GetFileType() (https://msdn.microsoft.com/de-de/library/windows/desktop/aa364960(v=vs.85).aspx) and check for FILE_TYPE_CHAR.

So with this it could be added to your lib, or ?!

PS: As alternative I would need kind if an "getHandle" method to get the Handle out of your struct to do such calls directly

Ok, I've added getHandle() function to the library which returns the HANDLE from the COM structure

[Apollon77]

then I use that one :-) thank you. Will report results later

works. Maybe "getCurrentHandle" is better because in fact it can only habdle one serial connection, or ?!
