The Free On-line Dictionary of Computing (19 January 2023):

CRLF

    /ker'l*f/, sometimes /kru'l*f/ or /C-R-L-F/ A
   carriage return (CR, ASCII 13) followed by a line feed
   (LF, ASCII 10).  Under Unix influence this usage has
   become less common because Unix uses just line feed as its
   line terminator.

   See newline, terpri.

The Jargon File (version 4.4.7, 29 Dec 2003):

crlf
 /ker'l@f/, /kru´l@f/, /C·R·L·F/, n.

    (often capitalized as ‘CRLF’) A carriage return (CR, ASCII 0001101)
    followed by a line feed (LF, ASCII 0001010). More loosely, whatever it
    takes to get you from the end of one line of text to the beginning of the
    next line. See newline. Under Unix influence this usage has become less
    common (Unix uses a bare line feed as its ‘CRLF’).
