A couple of interesting pics for ya:

I had previously posted this pic elsewhere in the forum ( DOSBox v0.73 Paradise Support ), and was twiddling a bit more with those features of DOSBox.

From the above-mentioned thread:

Two copies of DOSBox v0.73 running simultaneously with "serial2=nullmodem" for Mallard Software and Wesson International's "Air Traffic Controller", and "serial2=nullmodem server:127.0.0.1" for Microsoft's "Flight Simulator v4.0b" 😀

Hehe, and on the same topic:

Three copies of DOSBox v0.73 running subLogic's "Airline Transport Pilot" simultaneously with "ipx=true", "IPXNET STARTSERVER 213" for the master (using Nomissoft's "MONIPX01.DRV" for ATP), and "IPXNET CONNECT 127.0.0.1 213" for the two slaves (using Nomissoft's "SLMIPX01.DRV" for ATP). Note that "MONIPX01.DRV" and "SLMIPX01.DRV" are multi-monitor drivers for AS2 that work over a DOS IPX network.

Hehe, I would have ran an additional simultaneous fourth copy of ATP in DOSBox with MONIPX for the first pic, but alas... my PC couldn't keep up with the load 🤣!

And lastly, the same using Nomissoft's "Airline Simulator 2" (which was originally based on the old ATP):
