You will see “+" symbol often in the explanation or description of control codes from now on.

This symbol is used for legibility only and may not be input in your actual program.

3. Control Codes in the Text Mode

With the MX-80 Type II, two standard operation modes are available. One is the Text Mode which prints corresponding characters on normal ASCII coded inputs

and the other, the Bit Image Mode which permits printing of pictures and images in

dot configurations. The Text Mode is described in this section while the Bit Image Mode is covered in the following section.

The MX-80 Type I I has been designed as a terminal unit capable of various software controls. When control codes are transferred to the Printer, respective functions

governed by these codes such as form feed, line feed, etc. are executed immediately.

In order to permit the Printer to fully exhibit these functions, careful reading and thorough understanding of the following control codes are recommended. In this section, first the control codes in text mode are classified into groups. These two modes are not fully independent of each other in that parameters set in the Text

Mode are

also effective in the Bit Image.
