The USB communications device class (CDC) is designed for modems, and it can be hit-and-miss trying to speak to something else. Of course, that doesn't prevent one from ignoring that standard and just creating a bespoke USB device which happens to produce RS232, and FTDI do just that. FTDI's devices are better than standard CDC, but that's not a terribly high bar. ...
At one point FTDI had a reasonably good reputation, and I own one of those devices based on that reputation. I have used it with no obvious problems connecting a TRS Color Computer 3 to an iMac G3 for a floppy-drive emulator (DriveWire on the iMac), but I think only for that application so far. Are there any particular pitfalls I should watch out for with the FTDI device, when/if I can get back to working with it? - Mark
