Defines one or more new characters and stores them in
RAM for later use. EDS switch A3 must be set to OFF;
otherwise RAM is used as an input buffer only, not for
storing downloaded characters, and this command is
ignored.
nl is the character code of the first character to be
defined and n2 is the character code of the last charac-
ter to be defined. nl must be equal to or less than n2.
The data for each character starts with three bytes spec-
i&ing proportional spacing attributes: the first byte, mO,
specifies the left of the character; the second byte, ml,
specifies the character width; the third byte, ti, speci-
fies the right of the character.
These values must not exceed the following maximum
limits:
