Carriage Return (CR) Definition/Meaning:
A control code that is used to affect the format of printed or displayed
output. It indicates that the next data character is to appear in the leftmost
position on a line. In some serial printers, the CR code may cause a physical
movement of the printing carriage to the leftmost print position. In line
printers and serial printers designed for high productivity, the characters will
be correctly positioned although the printing of a line may commence at either
the left or the right end.
