Jeremy Davis posted this on the FreeDOS bugzilla a while back. I've just now re-discovered it, and I thought the info was so useful, it deserved its own newsitem:

Tony @ Instaview adds:
While its only for serial ports, RIFS is free for nocomm usage.. and has ( had? ) source code available....somewhere.
Used it on laptops years ago to get data in/out of them when it was too big for floppy, and was too much trouble to get network running ( used ghost via LPT to load them with dos and allen-bradley PLC software )...
