No. I found the relevant part in RFC 854 (Telnet)

      However, many systems and
      terminals do not treat CR and LF independently, and will have to
      go to some effort to simulate their effect.  (For example, some
      terminals do not have a CR independent of the LF, but on such
      terminals it may be possible to simulate a CR by backspacing.)
      Therefore, the sequence "CR LF" must be treated as a single "new
      line" character and used whenever their combined action is
      intended;
      [...]

Nice to know that there is RFC for everything. :)
