unix-unix-windows

I 'm working on the computer with windows-xp operationg system. I am connecting a unix machine (old version) which is connected with a robot by using telnet in the same network. Since unix version is very old, I couln't run the codes with emacs. I have another computer in the same network with ubuntu operating syste,m. I'd like to ask how can I mount the ubuntu to old version unix sytem as a folder on the windows system in order to use the emacs editor on the windows system.
