eof not handled in Windows files?

[isaac gouy]

It seems that several people have had problems
redirecting files to stdio using the Windows Console. 

In this program, eof never seems to match in the
receive loop but [] will match? I've tried creating
the file with notepad (which doesn't use an eof char)
and edlin which does insert an eof char. The eof char
inserted by edlin doesn't match with eof.

%% erl -noinput -s pipe start < data.txt

-module(pipe).
-compile(export_all).

start() ->
    spawn(pipe,init,[]).

init() ->
    Port = open_port({fd, 0, 1},[eof]),
    loop(Port).

loop(Port) ->
    receive
	{Port, eof} -> %% never matches !
            io:format("~n~s ~n", ["Matched eof"]),
            halt();
	{Port, {data, []}} -> 
            io:format("~n~s ~n", ["Matched []"]),
            halt();
	{Port, {data, What}} ->
	    Port ! {self(), {command, What}},
	    loop(Port)
    end.

Any suggestions on how to get eof to work?
