Other Functions → Zmodem File Transfer

 

Overview

Most Unix/Linux systems haven an implementation of Zmodem installed and preconfigured (if not, look for a package named lrzsz.zip on the internet, check if the Linux distribution offers a rzsz or lrzsz packet or ask our support). This program works very well to transfer files over SSH or telnet connection and integrates seamlessly with ZOC.

If rz/sz is available on the remote server (or lsz/rsz in some implementations), you can send a file from the remote host to ZOC by typing sz <filename(s)> on the remote shell. ZOC will then open the Zmodem download dialog and place the file into the local download directory (Options→Program Settings→Folders).

 

Transfer

To send a file to the remote machine, start ZOC's upload (Transfer menu). ZOC will then first send an rz command to the host to start the remote receiver and will then perform an upload. Alternately you can type rz on the remote shell and ZOC will open the upload file selection dialog.

 

Options

For file transfers using ZModem, ZOC offers a variety of options to control the transfer. These can be configured in the session profile (transfer section):

       
Upload File Management
 

These options apply only to uploads. They are only effective, if the receiver is able and willing to handle them, so they may or may not have an effect on an actual file transfer, depending on the receiver's Zmodem implementation (they work best when used to send files to Omen Technology's RZ or DSZ, which is available on various platforms including Unix, VMS and MS-DOS).
You can specify that you want the receiver to convert carriage returns and line feed according to its platform and you can suggest what the receiver should do if a file already exists on its machine. Options are to use the receiver's default action, to always overwrite files, to overwrite files if their file date is older, to resume an aborted file transfer or append the data to the existing files (the corresponding Unix SZ options are -p, -y, -n, -r, -+).

ASCII
 

The ASCII options are used when it is necessary to do an end-of-line character translation between different operating systems. It is useful when transferring text file, but has disastrous results when applying to binary data like ZIP files or executables.

Ignore time stamp
 

Select this option, if you want received files to be marked with the date/time of download, instead of being marked with the time stamp the file carried on the file system of the sender.
