I am pretty sure that the CRLF ending was inherited from CP/M.
- mmastrac 8y agoWhich, for those who don't know, inherited it down the chain from raw teletype machine baudot code (eg: see the videos by CuriousMarc on restoring early TTYs) - so it's 'technically correct'. Back then the machine could either feed a line OR return the carriage to the start. Not both!
- mdpopescu 8y agoMan, I forgot about those! You're right, I actually used a teletype for about a year on a PDP-11 clone.
- leoc 8y agoThat distinction between carriage return and line feed is in turn a general feature of physical typewriter mechanisms, though even manual typewriters would give you an automatic line feed every time you returned the carriage: https://www.youtube.com/watch?v=r97JHr13T98 https://www.youtube.com/watch?v=r97JHr13T98 . Line feed could also be manually controlled by using the platen knobs on the sides of the platen (the big roller which the paper was fed onto).
