Downloading a Draft/NLQ Character Set

The sequence to download characters for Draft/NLQ and Fast Draft is shown below:

Syntax:	ESC	=	count1 count2	font id	start
Decimal:	27	61	count1 count2	20	start
Hex:	1B	3D	count1 count2	14	start

There are two parts of the ESC = escape sequence.

Part one includes count 1, count 2, font ID byte, and the start code. Use this part once for each download command.

Part two is made up of one or more sequences of 13 bytes of data. The first two bytes of data are the 2 attribute bytes, and the remaining 11 bytes (3 through 13) are printable data. Repeat this part (2 attribute bytes plus 11 printable bytes) for each character you download:

attr1 attr2 col1 col2 col3 ... col11

Part One: Calculating Count 1, Count 2

Count 1, count 2	is a two-byte integer value, starting with the low order
	byte followed by the high order byte.
Font ID byte	is 20 (x14) for the Draft/NLQ font.
Start	The start code specifies the first download character. The
	download characters replace normal characters starting
	at that code point.
	For example, to download a character set that replaces
	characters starting with the uppercase letter ’A’, use a
	start code of 65 (x41).
