John, are your LPT ports "bi-directional?"  We recently discovered 
that the -AC (antenna control) function does not work if the parallel 
port is configured as bi-directional.  You might want to experiment 
with this, and let us know.

Ken is aware of the problem with -AC and bi-directional LPTs, but I 
don't know if he has a solution cooked yet.
