A transmitted default configuration report appears
in
the following form:
[880; 14;27;36;41 c
where
14,
27,
36, and
41
are
configuration codes
(see
Table 3-1). A transmitted status report
appears
in
this form:
[880;AB;CD;EF; ... ;YZn
where AB,
CD,
etc.
are
error codes
(see
Table 4-1).

CHARACTER
SET EXTENSION
The Model 880 Printer structure allows you
to
define the contents
of
the
"in-use"
character set
table. The in-use table is the table
of
characters
currently being printed. The contents
of
the in-
use table can be entirely replaced
by
alternate
character sets, or individual characters in the in-
use table can
be
replaced
by
individual charac-
ters invoked from alternate character sets. There
are
four
possible alternate character sets, called
GO,
G1, G2,
and
G3.
NOTE
Character set extension is possible
only
if
optional character sets are
installed on the Applications Con-
troller board.

Seven-Bit
Environment
Configuration codes
31, 32, 35, 36, 37,
and
38
define a 7-bit environment. Seven data bits define
a 128-character in-use table containing control
characters
in
columns 0 and 1 and printable char-
acters
in
columns 2 through 7. The
area
defined
by columns 2 through 7
is
called the
GL
(G-Ieft)
character set. The decimal equivalents
of
the
binary numbers formed by bits 1 through 4
are
the
row
numbers, and the decimal equivalents
of
the
binary numbers formed by bits 5 through 7
are
the
column numbers.
