10 is Line Feed, 12 is Form Feed 13 is Carriage Return In the teletype exchange with the teletype, the process would send the line feed and the teletype would respond with the carriage return as an acknowledgement of the line-feed (a shorthand for an x-on/x-off protocol). It took a long time for the print head of the tty to get back to the left margin (even at 120 to 300 baud (12 to 30 characters per second). Would not like to loose a character because the head is in motion.
