The interface includes two pull-up resistors connected to the same two
pins as the dit and dah paddle contacts. When the interface is
unplugged, these two pins go low and act like paddle contact closures.
Curious about the DAH's though, should be alternating dits and dahs...
To stop the DAH's (dit/dah's?), go to the Keyer menu and disable the
keyer paddle...
