ANSI assigns control functions to characters 80 hex through 9F hex and calls these characters
C1 codes. You can set the printer to either interpret 80 hex - 9F hex as control codes or not. The
ISU default status of this option is disabled.
You can toggle the status of the 8-bit control code enable from the Emulations Options Menu or
with escape sequences. The pertinent escape sequences are the ANSI private use sequences
described on page 12. In 8-bit mode, all of the lower contro l codes and ESC sequences remain
active. For example, you can use either PLD or ESC K for subscript printing. In 7-bit mode, only
ESC K is available.
If 8-bit control code interpretation is disabled, then the printer processes characters 80 hex
through 9F hex according to IBM PC character sets 1 or 2, depending on which is currently
selected. The default is character set 1. You can toggle the character set selection from the
Emulation Options Menu.
If 8-bit control code interpretation is disabled and character set 1 is active, then the printer strips
the most significant bit of characters 80 hex through 9F hex. For example, if you send 8A hex
when 8-bit control code interpretation is disabled and character set 1 is active, then the printer
treats 8A hex as 0A hex and performs a line feed.
