- It is easy to say what you should NOT be using, and that's Kermit
- or XMODEM. These two protocols have a VERY high overhead, and were
- really designed for slow (300 baud or so) comms over noisy lines.
-
- As to what you SHOULD be using - that's tougher, and depends on your
- modem. If you have a modem which *doesn't* do error correction
- itself, you should use an error-correcting protocol with a long packet
- length - YMODEM or XMODEM/1K are the most common. If, as most modern
- modems do, your modem itself does error detection/correction (ie, supports
- MNP4 or V42), you'd be better off with a protocol which assumes an
- error-free line. Of these the most common is ZMODEM, although slightly
- more efficient, if you have software which supports it, is YMODEM-G.

- I hope this has not added to your confusion!
