Note that on *nix, the "default text I/O layer" is probably effectively :raw and :crlf is not used unless requested, because the Unix convention is that text files store only <LF> at end-of-line and "\n" is <LF> in POSIX.

And the reason that you are supposed to specifically say "\015\012" instead of "\r\n" is that the latter is the current platform's notion of "carriage return/line feed" and might not be the ASCII CR/ASCII LF that is supposed to be used on the network. (I seem to recall that classic MacOS interpreted "\r\n" as "\012\015" as one example. I suspect EBCDIC systems may be even more bizarre.)
