How to use multiplayer?

Are there command line arguments to host, set port and join? Documentation is completely silent on this.

I've gotten MP working simply by having the devices on the same network and using the in game menus. My understanding is the IPX traffic is just translated to TCP/IP, so you should be able to have two computers on the same LAN network, host a game, and it will be discovered by the clients and able to connect. The only real consideration is what TCP port it is talking on and if you're being blocked by firewalls, but at least in Win11 it pops up a firewall passthough option.
