Thus spake <carheden@holly.colostate.edu>:
>What about STDIN?  1 is STDOUT, 2 is STDERR, is there a STDIN?  If so,

 STDIN is always determined by the direction of a pipe or redirection,
unless the man page for the command explicitly states that it uses a
character (like - for cpio or tar) to denote STDIN.

 For instance:

$ tar cvf - files | rsh remotemachine "cd dir; tar xvf -"

 In this case, the "-" is referring to STDOUT the first time it is used
and STDIN the second.

 Something analogous to "copy con <filename>" would be:

$ cat > file
foo
bar
^C

 Then file would contain the two lines typed in.
