(1) ASCII control codes are sometimes used to "formalize" a communications session
between communication devices. (2)
have user-defined meanings, and may vary in use between sessions or devices. (3)
often used as a general "stop transmission character." (4) Codes used to control cursor
position may be used to control print devices, and move the print head accordingly. However,
not all devices support the full set of positioning codes.
