Zusammenfassung:	Disclosed are methods for transmitting data to a downhole tool. The methods include the option of confirming receipt and implementation of the transmitted data by the downhole tool. The disclosed methods utilize changes in RPM of the tool to convey the data through three separate changes in RPM. The changes in RPM are used to generate pulses suitable for identifying preprogrammed actions found within the memory of the downhole tool.
