There isn't one.

Sorry, this is not supported.

I think the KX3 Utility uses some type of special "direct write to
non-volatile memory address" command.  They don't publish how to do that
because it would be too easy to really mess up the KX3 firmware if they did.

A crude work around would involve special hardware (two open collector
keying circuits) to simulate tapping the dot and dash paddles in the right
sequence at a certain speed, so you wouldn't have to program the memories
by sending on the paddle yourself.  But writing new code to do that is
probably not worth the effort.
