 Responses to certain commands are multi-line.  In these cases, which
   are clearly indicated below, after sending the first line of the
   response and a CRLF, any additional lines are sent, each terminated

   final line is sent, consisting of a termination octet (decimal code
   046, ".") and a CRLF pair.
