Ken, I've never used EQMOD through the handset, but it's my understanding it becomes passive - effectively just part of the communication connection. EQMOD includes more sophisticated pointing modelling than the handset. You can do n-point sky models on either side of the meridian independently if need be (where "n" can be a very large number).
Basically you tell your planetarium software to point at an object, align it centrally in your scope (visually, by plate solving, or manually off camera image) then issue a "Sync" command from software (they all have various ways of doing this if you read the manual). In EQMOD you can choose how it reacts to a received Sync - e.g. if it adds it to the existing pointing model, or syncs the entire existing model.
Most people that start using EQMOD find it hard to go back to the handset.....
