iirc that ANSI standard was based on the DEC VT100, so
if you read the
VT100 user manual (available on Manx I think) you'll have a good idea
of what everything is supposed to do.
Other way 'round, I think. The original applicable ANSI standard is
X3.41-1974, which defines the simpler escape sequences. The VT100
wasn't introduced until 1978.
Additional sequences for alternate character sets were defined by
X3.64-1979.
Both standards underwent revisions as the years went on, but neither
standard is currently active, being supplanted by ISO 2022 and 6429,
respectively.
FWIW, well into the 1980's, the ANSI escape sequences were mostly
ignored by the industry (DEC being an exception). Hence the
evolution of TERMCAP and CURSES.
