sz, sx, sb Beginner Help

This document describes how to use ZModem's sz command, XModem's sx command, and YModem's sb command to download files from your World account to your local host computer.

Please note that most software will automatically recognize the beginning of a ZModem download when World begins sending (that is, as soon as you hit <enter> after "sz filename"). With XModem and YModem, this is rarely the case. After running sx or sb and hitting <enter> you normally have to do something, usually make a menu choice or hit a control key, to tell your software to begin receiving the file.

Further, please note that to abort a ZModem, XModem, or YModem file transfer, use the Control-x character. You may need to type several Control-x characters before the transfer aborts.

Sending files with ZModem

All World commands will be prefixed with the string "world%" to indicate that you should issue the command at the World's UNIX prompt.

To send a text file from World to your local host (download) use:

world% sz -a filename

The filename you specify will be downloaded to your local host.

To send a binary file from World to your local host (download) where the -b flag (for binary) is the default, use: world% sz filename

Sending files with XModem

  To send a text file from World to your local host (download):

	world%   sx  -a filename

  To send a binary file from World to your local host (download) where
  the -b flag (for binary) is the default, use:

	world%   sx  filename

Sending files with YModem

To send a text file from World to your local host (download):

world% sb -a filename

To send a binary file from World to your local host (download) where the -b flag (for binary) is the default, use: world% sb filename

For complete details on the Unix versions of ZModem, XModem, or YModem, please refer to the online manual pages:

        world%   man  sz

sz, sx, sb Advanced Help


One advanced file transfer feature combines the use of the UNIX pipe
command with the file transfer protocols.  Consider the command 'help
Primer', which displays the online copy of the World's user guide.
You can download this file using ZModem with the following command:

        world%   help  primer | sz  -a  -

This causes the text output from the 'help primer' command to get
sent directly to the download command.

Using Zmodem with a remote Internet host

If you rlogin from The World to an account on a second Internet site and that host supports zmodem file transfer, use the following options:

From World to another host:

world% rlogin -8 host.site.domain

From another host to World:

otherhost% rlogin -8 world.std.com

Using rlogin in this way allows you to use the sz command from the remote Internet site to transfer files from that site, through The World to your local host computer.

The -8 option creates an 8-bit clean connection which will allow reliable file transfer. These settings will disable the normal rlogin escape character (usually ~). To logout use the UNIX command 'exit' or 'control-d'.
