Hi.  Glenn is right about the fact that -AC sends band data to LPT1,
which can be used for antenna switching via the Top Ten Band Decoder.

However, LPT1 can also be simultaneously used for cw keying.  In
fact, the Top Ten Band Decoder has a keying transistor built in.  All
you need to do is to connect LPT1 to the BD with a full 25 wire
serial cable (which brings the keying info into the decoder), and
then key the transmitter via the RCA jack on the back of the decoder.
