I
Number of Columns
You may choose either 80
or
132 columns on the
screen. Many programs make that choice for you.
1be 132-column display is convenient for spread-
sheets
or
horizontal-format documents.
Screen-Saver
The
screen-saver feature makes the screen go
blankafter 10,20,or 30 minutes
of
inactivity. You
can change this time-out in set up. To tum the
screen saver
on
or
off, refer to the local key com-
mands for your keyboard (later in this chapter).
Blanking out the display conserves the phosphor
coating inside the face
of
the screen. Any new data
from
the keyboard or host makes the display reap-
pear.
Resetting the Terminal
The terminal offers several ways to reset:
Partial reset
Enter set up and select CLEAR COMMUNICA-
TION. This disables any currently enabled print
mode, clears the COMI and COM2 port buffers,
and unlocks the keyboard.
Nonvolatile reset
Turn the terminal
off
and
on again,
or
enter set up
and select
RESET
TERMINAL. This severs all
communicationwithother systemunits(computer,
printer, etc.),so data not saved
in
permanent mem-
Oly
may be lost. Operating parameters revert to the
last values saved in permanent memory.

basis.
FunctlAlt
Key
With this terminal, you have a choice
of
three
keyboards: AT, ASCII,
or
DEC style. One
of
the
keys (located left
of
the space bar) has a different
name on each keyboard. On the ASCII keyboard,
it is labeled
Funct;
on the
AT
and DEC-style
keyboards, it is the left
Ait
key.
With an AT or ASCII keyboard, the KEYBOARD
menu options are: FUNCT, META, 3rd LEG-
END,
or
COMPOSE.
With a DEC-style keyboard, the same menu and
command code options are: FUNCT, META,
or
3rdLEGEND.
NOTE: If you are using a DEC-style key-
board,
use
the Compose Character key to
accomplish the compose function.
The FUNCT Option
Once defining the key, pressing itand another key
sends the ASCII code for that key, bracketed
by
the start-of-header (SOH) andcarriage return (CR)
control characters.
It
works only with alphanu-
meric keys, not with the editing keys.
The META Option
The FunctlAlt key, pressed simultaneously with
an
alphanumeric key, sends the alphanumeric key's
code, with the high bit set.
