ESC
- ASCII Code 27 - Prefix code for a char-
acter sequence which changes the print-
ing format configuration from that
established upon initialization or pre-
viously transmitted configuration
sequences. Each sequence consists of
the ESC prefix immediately followed by
a modifier code defining the printing
format characteristic to be modified.
The modifier may be followed by zero to
three bytes of ASCII numeric data which
established the new value to be assigned.
The following list defines each of the
ESC sequences.
NOTE
The spaces shown below, between the segments
of the ESC sequences are inserted for clarity
only. The sequence must be transmitted as
one continuous group with no intervening
spaces or other codes such as CR's or spaces.
See Appendix A for examples.

- Clear all Vertical Tab stops.
- Set a Vertical Tab stop at line number NNN . .
(NNN is an ASCII decimal number in the
range of
001
to 225. Line number
001
is
Top of Form.) A maximum of 16 Vertical
Tabs Illay be set.
- Clear all Horizontal Tab stops.
- Set a Horizontal Tab stop at column number
NNN. (NNN is an ASCII decimal number in
the range of
001
to 220. Column
001
is
the left-most column.) Tabs set beyond
the current maximum number of columns are
ignored. A maximum of 8 Horizontal Tabs
may be set.
- Set Form Length to NNN lines. (NNN is an
ASCII decimal number in the range of
001
to 254.) Actual length in inches depends
upon whether the line spacing is 6 or 8
lines/inch. This sequence also clears all
current Vertical Tab stops and Skip-Over-
Perforation and establishes the current
position as Top-Of-Form; therefore, these
functions must be reentered each time
Form Length is changed.
