open a remote unix shell from a windows emacs via TRAMP

[Terrence Brannon]

Hello, I have no problem editing files via pscp on my Windows 7 64-bit machine running

GNU Emacs 23.3.1 (i386-mingw-nt6.1.7601) of 2011-03-10 on 3249CTO

However, when I type M-x shell, I get this error:

Debugger entered--Lisp error: (wrong-type-argument processp nil)

  set-process-sentinel(nil shell-write-history-on-exit)

  shell-mode()

  shell(nil)

  call-interactively(shell t nil)
