Chapter 1 The IGP/PGL Emulation
Normal Mode
Normal Mode commands print data in a line printer format until a Special
Function Control Code (SFCC) is detected.
Commands accessible in the Normal Mode are summarized in Table 1 and
fully described on the referenced page. Some Normal Mode commands can
also be used in other modes: Compressed Print, Expand, Ignore, Select
Format, and Vertical Line Spacing, which are Normal Mode commands, can
also be used in the Execute Form Mode; the Multinational Character Set
command can be used in the Normal or Create Modes. Carriage Return,
Form Feed, Line Feed, EVFU commands, and Paper Slew commands also
operate in the Normal Mode.
Quiet Mode
In this mode, the host processes all data as ASCII characters without any IGP
interpretation — the IGP is disabled and all IGP commands are ignored. The
IGP looks only for the (cc)LISTEN command.
Note All IGP commands must be entered in UPPERCASE, and
each command line must be followed immediately by a line
feed (or carriage return with line feed terminator) or a paper
motion command.
