CONTROL CODE DEFINITIONS

The control codes are single character action codes in the range

0 - 31 decimal in the ASCII code chart. The following are those codes, which are relevant to this emulation.

BEL	Bell: The printer's audible alarm will sound for 1/2 second when the
	bell code is received by the printer.
	Decimal:	7
	Hex:	07H
	BASIC:	CHR$(7);
BS	Backspace (08H): The backspace code will set the active print position
	one character position to the left at the current CPI, unless the new
	location precedes the left margin. In this case, the active position will
	be set to the left margin.
	Indeterminate conditions: If the right margin has been exceeded
	the backspace is ignored.
	Decimal:	8
	Hex:	08H
	BASIC:	CHR$(8);
HT	Horizontal Tab: HT will set the active print position to the next
	horizontal tab position.
	Indeterminate conditions: If there are tab(s) set but no tab(s) are
	set between the active print position and the right margin, the active
	print position will advance to the right margin.
	If there are no tabs set, the active print position will advance to the
	right margin.
	Decimal:	9
	Hex:	09H
	BASIC:	CHR$(9);

NOTE

The emulation initially sets a horizontal tab stop every eight characters.

	execute a carriage return prior to executing the LF.
