Driver.CredentialsHandling (PROP) ¶ PROPERTY CredentialsHandling : IDatasources.IDriverCredentialsHandling If this kind of driver requires credentials for logging in to a specific kind of device, then this property can return an object handling the assignment of credentials.

Driver.DataByteOrder (PROP) ¶ PROPERTY DataByteOrder : IDatasources.ByteOrder Returns the byteorder of data managed by this instance. Note It is not expected that this value changes at runtime.
