I have to be running the command "copy con somefilename". And I have
to be able to tell this command to terminate in the normal fashion.
Normally when operating on the command line, one uses either F6 or
Ctrl-Z. This is a very old trick stemming from oldschool DOS. I can't
specify why I am doing this certain thing this way, for reasons of not
giving away the idea I have prematurely. I guess the real problem is
right where I input '^Z'. Does anybody have any clue on how to do
this?
