OK, if this is realy an emergency case there are other ways.
It to some degree depends on the number and size of the files, but...

I now and then copy files betweeen systems where I have no other
communication then my terminal emulators by cut-n-pasting uuencoded
data.

On the source system :

$ MC tcpip$uuencode myfile sys$output

that will give something like :

$ mc tcpip$uuencode a.exe sys$output
-----begin 750 a.exe
M`P````````!,`@``(`$``&@```"8````N`````````````,`````````````
M``````````$```````````````````#__________P(````H````P9+K&@``
M```!`````````!`````P`````````$`#``#_____2``!````````````````
...
... (a number of similar lines...)
...
M````````````````````````````````````````````````````````````
=````````````````````````````````````````
`
end
$

Mark all lines from "begin" to "end" and "copy".

On the target :

$ mc tcpip$uudecode sys$input

and "paste" into the emulator, maybe finish with a <ctrl-Z>.

Repeat for each file.

For a number of smaller files, this can be done on a ZIP file
with all or a number of the files.

If you do not have TCPIP services, use the UU-tools in TCPWare.
If they for som reason fails to run, use some freeware UU-tool.

	
It very much depends on the number of files, the sizes of the files,
if this is a one-off case and so on. You have as far as I know
failed to give details on those points.
