Hi, I put together bundle with couple of bits: launcher utility, fujinet-pc, netsio hub, and custom device file - all necessary pieces to connect emulated Atari (Altirra) with FujiNet.
If interested, Fujinet-PC launcher repository is here: https://github.com/a8jan/fujinet-pc-launcher
Instructions are here: https://github.com/a8jan/fujinet-pc-launcher/blob/master/Install.md and video instructions:
