Using
Your
Keyboard
Many
keys
on
the
3270
terminal
keyboard
function
differently
when
the
terminal
Is
acting
as
a
Dasher
D210.
Referring
to
Appendix
A,
"Terminal
Keyboard
Maps,"
select
the
keyboard
map
that
corresponds
to
the
type
of
3270
keyboard
you
are
using.
For
example,
If
you
are
using
a
Converged
keyboard,
use
the
map
called
"Using
a
3270
Converged
Keyboard
as

Typematic
Keys
BREAK
Function
A
typematic
key
Is a
key
that
repeats
Its
function
when
you
hold
It
down.
All
keys
that
are
typematic
on
your
3270
keyboard
continue
to
be
typematic.
The
actual
DG
D210
has
a
REPT
key
which
Increases
the
typematic
rate
to 30
characters
per
second.
The
3270
keys
repeat
at
the
rate
of
the
specific
keyboard
In
use.
The
BREAK
function
acts
differently
depending
on
the
application
program
that
your
system
Is
using.
This
function
produces
a
short
break
of 0.2333
second;
a
Shift BREAK
function
produces
a
long
break
of
3.5
seconds.
See
your
system
administrator
for
more
Information.
Controi
Mode/Control
Shift
Control
functions
are
provided
by a
control
key on
keyboards
where
a
control
key
Is
available.
Depending
on
the
terminal
type,
the
control
key
provides
either
a
Control
Shift
or
Control
Mode
function.
The
Control
Shift
function
allows
you
to
select
multiple functions while
the
control key Is
pressed.
The
Control Mode
function allows you to
enter
only
one
control
sequence.
Both Control Shift
and
Control Mode
are
Indicated by a left-facing
arrow
displayed
In
the
OIA.
On all keyboards, using
the
extension
mode
key or
the
Extended
Select
key
followed by the control key Invokes the Control Mode on/off function.
See
Figure 1-2 on
page
1-8 through Figure 1-4 on
page
1-9 for the location of
these
keys.
Function
Keys
A Pseudo-shift
state
Is provided to allow shifted versions of PF13—PF24 on
Base
and Enhanced keyboards. The Pseudo-shift key Is the
DUP
or
PA1
key on
the
Base
and
the
Enhanced keyboards. An "S" Is displayed In column 40 of
the
status
line
when
you
are
In
Pseudo-shift
state.
Pseudo-shift only applies to keys
as
defined In the keyboard maps. Any other keys
pressed during this state cause a keyboard lock. Pressing the
DUP
or
PA1
key
again
also
causes
an
exit
from
Pseudo-shift.
Control
and
Pseudo-shift
are
not
valid
at
the
same
time.
Therefore,
only
three
states
of
the
PF keys
are
available: unshlfted, shifted (Pseudo-shift) and CTRL
(control).
Understanding
Your
Status
Line
The
status
line gives you Indications of
the
operating
state
of your terminal.
Symbols, characters, and numbers
appear
In the status line to Inform you of
conditions; for example, ifyour keyboard Is locked. Ifit Is In upper shift, or
If
the
system Is busy. Refer to Table 2-9 on page 2-16for Information that can
appear
In
the
status
line,
and
what
that
information
means.
