As a rule, z, y, and xmodem are also protocols for file transfer over a dialup connection. However, I am aware of at least one client that can do x,y,zmodem over telnet. It's called ztelnet, and is for 'nix machines. > my question is this: how do I download using this Kermit from my ISP's > unix server which I only know uses sx, sz and sy proto's/commands?? Kermit is a totally unrelated to sz. sz/rz do zmodem, ymodem and xmodem transfers only. > do I type sz -b at the unix prompt? then go into kermit transfer mode and > wait? are zmodem, xmodem, ymodem compatible or can they be made compatible > with kermit transfer mode?? sz is able to send via x/y/zmodem. It is not able to send Kermit. Once sz is sending, your client must be able to invoke its own "rz" equivalent, which will save the file where you want it. Over dialup, I always used Telix for doing kermit/x/y/z, but once Delphi went telnet access only, kermit ability went by the wayside, and I had only the option of ztelnet for downloading binaries from there. You could read the thread where this was discussed a few months ago: http://www.mail-archive.com/[EMAIL PROTECTED]/msg00898.html The pertinent part (by Howard) is this: "Zmodem-over-telnet is possible in DOS if you use a comm program that supports int14 or fossil on top of tcpport or rlfossil, but uploads may be a problem. I would recommend ftp for DOS if at all possible." That pretty much sums it up. x/y/zmodem and Kermit are all transfer/error correction protocols designed in the era of dialup. While it's *possible* to use them over tcp/ip, software to do so is rare. -- Steve Ackman http://twoloonscoffee.com (Need green beans?) http://twovoyagers.com (glass, linux & other stuff)
