Using Hyperterminal with the simplex 4100u

Has anyone here ever used Hyperterminal with the simplex 4100u im trying to connect but having difficulty.
Found this document ( safetyproductstraining.com - This website is for sale! - safetyproductstraining Resources and Information. ) which speaks to using hyperterminal to connect to the service port and also refers to another document (Using the 4100U Service Port and Hyper Terminal).
If anyone has this document or knows how to make the connection and is willing to share id be grateful for the assistance
