Defines one or more new draft characters and stores them in RAM

for later use, Memory Switch must be set to “DOWNLOAD”; other-

wise RAM is used as an input buffer, not for downloading charac-

ters, and this command is ignored. Draft mode must be selected

before this command is executed.

nZ is the character code of the first character defined and n2 is the

character code of the last character defined. nZ must be equal to or

less than n2.

Each character is defined by an attribute byte (m0) and 11 data bytes

(mZ,m2,...mZZ).

The most significant bit of the attribute byte is 0 if the character is

an ascender (positioned entirely above the baseline) or 1 if it is a

descender (descending below the baseline). The attribute byte also

indicates the amount of white space to the left of the character (0 to

7 dots, specified by bits 4 to 6), and the width of the character cell,

including this space (4 to 15 dots, specified by bits 0 to 3). The left

space and cell width attributes areused only in proportional spacing.

Each data byte indicates eight vertical dots, with the most significant

bit being the top dot, and the least significant bit being the bottom

dot.
