Dave,
Take a look at the following link
which is some developers
information on the rotor control that Ron asked about. From what I
can gather it is not an RS232 interface but works with some plug
in boards and drivers that you can access through DDE or Windows
messaging. It looks like they would be happy to answer questions
or help with the interface if you want to get involved with that.
My guess is that the more software that supports them the happier
they are.
