a test file may help...and exact equipment is what would be neccessary to duplicate the issue, unless you're saying that you've taken the equipment out of the scenario and are just viewing the strings as they come through via hyperterminal. If this is the case it leads me to believe its still a cacheing type of issue I was originally referring to (but understanding that the cacheing issue could be in the remote, the antenna or the msc) and would just be a function/limitation of the product.

My next question would be what brand and model number of receiver are you using, and can you do a repeat while pressed/held type of functionality and/or is there a ramp function? does IR work? use that instead.
