I've been flying the DC-3 in MSFS 2K2 for a while now... then I have a question if I can make a survo drive guages for a pit. Where can I find the URL or links to learn about MSFS2002 output signals... and the programming language to interface between the sim and the hardware? Thank you in advance for the reply.
