It Works!!! Now, who can I talk to about maybe getting this as an option for the Aux/PC selection. Would be nice to have "Disabled Hardware Handshaking - Only useful for some homebrew aux adapters". This is what I modified in celestronaux.cpp.

m_IsRTSCTS = false;
LOG_ERROR("TEMP HACK -- Set m_IsRTSCTS to false.");

This simply forces RTS/CTS to false. For whatever reason it gets set to true with the mount adapter I'm using even though it's not using it at the serial side.
