In order to use the TI reader within RealBasic we had to implement some of the serial protocol ourselves.  In order to use the TI Reader with the [wiki:ISO15693] protocol you must first generate a command encapsulated in the TI protocol and have the payload of the command be the [wiki:ISO15693] command.  Only 3 of the commands are necessary, Inventory All Slots, Inventory 1 Slot and Silence.
