Is there any use in API for CTS line in order to open the port?
You have asked about it.
All opreations we can perform with the serial port require the port handle and the last one can be obtained just from the CreateFile. It's about regullar/common/well-known WinAPI. I don't know, maybe, a device driver or something can help you.
If you'll find something let me know please.
I think you have a device connected to the PC and when the device is supposed to send something it has to notify the PC?
I think, the serial port must be open always in the case. And if you see a changes in CTS/RTS/whatever you can start your actions.
