Bidirectional clipboard sync between any Windows machine (from 95 to 10) and any other Node.js–capable machine. You simply need to have the two machines connected with a serial port. To do so in QEMU you simply need to add -serial pty to the command line. The serial port dev path will be printed at vm start, if it's different than ttys000 you may need to change it in index.js.

To build the Windows executable you may need Visual C++ 6.0. To run the Node.js script you simply need to run:

cd js
yarn install
yarn start
