Hi everyone
I was using this tool when i started to make my own controller.
I let it in stand by for a long time (i moved twice and started to run a business) and recently i found a solution to bring back the Zitronen plugin to life with win10.
This tool is very usefull to try and debug code, so i forked this tool to make it compliant with the version 0.19.1 of the Zitronen plugin, essentially in updating the VesselData packet, added controls for SAS, navball mode, liquid fuel and oxidizer total and current stage and "vectors"
It is still open source and can be found on GitHub : https://github.com/Jimbo-Farrar/KSPSerialIODebugTool (there is a executable version in the directory bin/Release/)
