svn+ssh ppk password prompt not appearing while telnetted to a Windows box

I'm telnetting to a Windows box and attempting to use the Collabnet svn command line client to access a repository using a URL that starts with svn+ssh.
The [tunnels] ssh setting in my config file is pointing to the TortoisePlink.exe installed by TortoiseSVN and my own password protected key file.)

The telnet terminal just hangs presumably because TortoisePlink.exe is trying to display a password prompt for the key file in a popup dialog which of course isn't supported by the telnet client.
Is there a workaround for this, or is the only option to remote desktop to the Windows box then run svn commands inside a console window so that TortoisePlink.exe can display its popup window?

(I tried using the Putty plink.exe in the ssh setting in the hope that is would prompt for a password, but it just hangs.)
