FastLynx 2 supports IPX.
Fastlynx 3 supports USB based LPT ports, IIRC, but costs money. [Fastlynx 2 does not know how to handle them, and tries to talk directly to the LPT port's IO range, which, does not respond, because the physical hardware it expects at that address, is not present.]

I only have experience with FastLynx 2, and I can assert that it was "Game changing" back in the days of yore. It can do pretty good transfers over an LPT cable in Enchanced Mode. It can ALSO be bootstrapped on systems that have DOS's CTTY application, and no functional floppy drive.

(I provide both links, as the firewall at work blocks EVERYTHING FUN. Even MinusZeroDegrees. Why? I do not know, and cannot begin to imagine.)
FX3 could be used with a laplink cable, (but works better with an FX cable, which is wired different! The manual linked above contains the pinout for this cable to make one yourself, but a premade laplink lpt cable works fine. See page 30 of the manual for this pinout.) a USB to LPT cable, and win9x.
The user interface (once connected) is a lot like Midnight Commander, if you remember that.
