[TriLUG] CR/LF

[Rick DeNatale]

It does matter.  In a binary mode transfer you want a byte for byte
copy, you don't want to translate bytes which happen to be cr, lf,
etc.

ASCII mode tells the FTP client and server that line end sequences and
end of file characters should be translated when necessary.
