[CQ-Contest] PC control of Yaesu G-1000DXA rotor?

[KØHB]

I have a Yaesu G-1000DXA antenna rotor.  This rotor can be come under PC control
(CT, and other logging programs) with addition of a GS-232A adapter.  I'm not
sure what's inside that gadget, but it costs $540, about the cost of the rest of
the rotor itself.  Has anyone here homebrewed up a replacement for this thing?
Care to share your schematic and code?
