B.2 SIMPLE_TEXT_OUTPUT
Table B-2 defines how the programmatic methods of the SIMPLE_TEXT_OUPUT protocol could
be implemented as PC ANSI or ANSI X3.64 terminals. Detailed descriptions of PC ANSI and
ANSI X3.64 escape sequences are as follows. The same type of operations can be supported via a
PC AT type INT 10h interface.
