Some CW interfaces key on the opposite line level (transmit at rest / key backwards). New "Invert keying (active-LOW)" toggle flips the asserted level for both the CW and PTT lines, and the idle state drives both lines to their inactive level accordingly so an active-low rig isn't left keyed at rest. Default off = N1MM convention (line HIGH = active).
