Defines new characters and stores them in RAM for later use. EDS switch A-2 must be OFF and the optional RAM cartridge, RC-32Z, must be installed; otherwise RAM is used as an input buffer, not downloading characters, and this command is ignored.

Downloading characters in IBM mode requires Dot Pattern data and Character Index Table data. Dot Pattern data controls which pins fire when printing a character. Index Table data is placed in a “lookup table” that provides information on where Dot Pattern data is stored in memory and defines certain attributes of the character.

(nl + n2 x 256) give the number of bytes to be downloaded.

n3 and n4 indicate the low order and high order addresses in which data is to be stored. n3 should be 15 and n4 should be 128 for this printer.

n5 determines the character mode to be downloaded, as shown below:

ml through m9 indicate Index Table data.

ml and m2 indicate the adress where Dot Pattern is stored. ml is the high-order byte. m3 indicates the number of columns in the charac- ter memory, and m4 indicates the number of columns in the character.

m.5 through m9 are compression mask bits. Data compression allows the efficient use of memory in storing downloaded charac- ters providing space for more characters than would be available without compression. The printer repeats the previous dot column in the current column when the current column compression mask bit is set to 1.

It is necessary to define all of Index Table data before the Dot Pattern data to download many characters.
