32 Line Matrix Printer Code V Programmer's Reference Manual

Chapter 2 Command Codes

Comments Some host systems automatically generate forms control codes

such as CR or LF after a specific number of characters. These

host generated forms control codes could prematurely terminate

the graphics command sequence. The Free Format command

allows the Code V to accept incoming data as one continuous

stream even though the data stream may include host generated

forms control codes.

Free Format is available when the Code V is in the Graphics

Mode. When enabled, the Code V recognizes only the Free

Format terminator commands (Table 12) for forms control until

the Free Format is disabled. If the Graphics Mode is disabled,

Free Format command is automatically disabled. You can use

the Free Format command in repeated forms.

NOTE: Free Format commands may be used in the normal Graphics Mode

even though Free Format is not enabled. However, when the Free

Format command

enabled, the only valid terminators are the Free

Format commands; others are ignored.

Example The following command enables and disables Free Format in the

Graphics Mode.
