Comments:

This function requires that the VTSIO driver be installed. Please refer to the topic, Communicating Directly With Hardware for more details. This is a high priority function. If used in a statement or action trigger, it will be evaluated at a very fast rate. MemIn should be used sparingly to avoid reduced system performance. In certain cases, the registry may need to be modified to allow access to the memory location.
