[h-e-w] GNU Emacs 21.3.1 - UWin ksh93 - Windoze XP (frustration)

[odoncaoa]

Greetings,

I'm trying to re-aquaint gnu emacs with uwin ksh on windoze xp. For whatever
reason, I get the process to execute, but it then immediately exits. I have
fixed this problem in days gone by, but, hey, I'm back ;^) I'm aware of all of
 the elisp incantations necessary to make them play nicely together. I'm
at a bit of a loss at the moment? The ksh should not be exiting. Here's the
output that is left in the *shell* buffer:
   $

   Process shell finished

This is what script looks like:

On Fri Sep 23 14:17:16 EDT 2005, Joe Kelsey KELSEY at avtcorp.com, posted the
a similar query on the UWin ksh list:
          "I run UWIN and NT Emacs.  I am currently having a lot of trouble
           getting Emacs to start a subshell with UWIN ksh as the shell. Every
           time I try, ksh always prints the command prompt and then
immediately
           exits.
           ...
           Has anyone else tried to get UWIN ksh to work with NT Emacs?  Does
           anyone have any ideas?

/Joe"
