Oh well, if you want to investigate things, or actually want to get something to fail it or disconnect it on purpose, take a tool like this angle grinder, put it on a socket with same phase and neutral with the printer. Start comms, and then power up the angle grinder, and i give it a very good chance your comms will fail when that happens, due to reactive current issues. On a large scale if you are located right near the mid voltage to low votage trafo box, or if your phases have capacitors or reactors for reactive power, then comms have a chance, but these things are more for industrial areas. Or, on a low scale what it can be done, if the used psu has overkill capacitors or active cos phi improvement/control (hi-end atxs), then comms again have a chance to survive, but i think chances to survive without any of that are low. If it doesnt fail with the angle grinder, then time to try an old style metal arc-welder - thats probably better at killing comms - almost a guarantee. Let us know how that worked :) And have fun, lol :)
Just stuff like this have little to do with the ics themselves. The ft232rl is probably an old one by now, and as such probably it could be said its in the reliable part of its lifecycle. For this conversion probably all ics solutions are rather old by now, so i wouldnt expect much differences from one to another.
