• CR = Carriage Return (\r , 0x0D in hexadecimal, 13 in decimal) — moves the cursor to the beginning of the line without advancing to the next line.
• LF = Line Feed (\n , 0x0A in hexadecimal, 10 in decimal) — moves the cursor down to the next line without returning to the beginning of the line.

A CR immediately followed by a LF (CRLF, \r\n , or 0x0D0A ) moves the cursor to the beginning of the line and then down to the next line.
