When I try to download, though, it gives me a ton of errors. However, even XMODEM is an error-correcting protocol, right? ZMODEM just plugs on, and I can eventually get at least one file through. Whether it will work with batch transfers, I'm not sure. (I think it does, though.) It would be nice to see a full ZMODEM that supported error correction, data compression, and the rest of it. I have a paper on the ZMODEM protocol that I got from somewhere and would like to try writing a full ZMODEM. If you want a copy, let me know and I'll mail it to you. If there's enough interest, I'll post the thing.
