Oh, but be careful with gender changers because with serial
connections, because not all serial cables are created equal; often, a
double-female-ended cable will be a null modem cable (with RX/TX wires
crossed), but not always.  You can test your cable with a continuity
tester to make sure that the pins on each end are all the same pin.
The K3 needs a standard cable, not a null modem cable.  See
