ConnectionError Property (Terminal)
Gets the error number that describes the specific cause of the most recent general connection failure (if the last returned error has the value ErrConnectionError).
Object.ConnectionError As Long
Use ConnectionErrorMessage to retrieve the error message. If no connection failure occurred, this property returns zero.

If you use ConnectionError for errors other than ErrConnectionError, you will retrieve information that is not valid for the current error condition.
