As you have found, GetComLineStatus isn't in CVI 5.0, it was introduced in later versions.

Unfortunately, if you need to check the line status in CVI 5.0, you will have to use the Windows SDK functions for accessing, reading and writing COM ports (in particular, the GetCommModemStatus() function for finding the state of the CTS line). Regrettably, I think you cannot use these functions in combination with the CVI RS-232 library.
