Introduction
PERIPHERAL DEVICE CONNECTION
Peripheral
devices,
such
as
printers
and
plotters,
are
connected to
the
terminal
in
an
Alternate
Peripheral Interface network.
Either
the
standard
2628A, option 046 (2628A),
or
option
026
(2625A) is
required
to
connect to
an
Alternate
Peripheral
Interface
network.
CONFIGURATION OF THE TERMINAL
Configuration
of
the
terminal
is performed
using
menus.
These
include a Global
Configuration
menu,
a
Terminal
Configuration
menu,
and
four
data
communication
(datacomm)
menus
for
the
HP
personality
of
the
2625A
and
for
the
2628A.
The
IBM
personality
of
the
2625A
has
a
menu
of
its
own. Selections
made
on
these
menus
determine,
among
other
things,
terminal
characteristics,
coordination of
data
transfer
between
the
terminal
and
the
host
computer,
parity
type,
and
rate
of
data
transfer.
DATA
COMMUNICATIONS
The
terminal
can
be connected
to
an
HP
host
computer
in
either
a point-to-point
or
multipoint
configuration,
either
hardwired
or
through
modems.
Port
2
of
the
standard
2625A
terminal
is
connected to
an
IBM
computer
in
a
multipoint
network, for Bisync
operation.
In
addition,
option 021
of
either
the
2625A
or
the
2628A
can
be connected to a
distributed
systems
network
(DSN), a form
of
multipoint
network.
The
2628A
or
the
HP
personality
of
the
2625A
can
transfer
data
either
one
character
at
a
time
or
in
blocks of one
line
or
one
page
(one screenful)
at
rates
up
to 19,200
baud.
Switching
between
the
HP
and
IBM
personalities
of
the
2625A
terminal
isdone
with
a function
key.
Each
port
remains
active, even
though
it
is
not
currently
selected.
GRAPHICS
Option 523
incorporates
a
graphics
capability
into
both
the
2625A
and
the
2628A
terminals.
Refer to Appendix D for information.
WORD PROCESSING
Option 528
incorporates
the
HPWORD word processing
capability
into
the
2625A
terminal.
This
capability
is
standard
with
the
2628A. Appendix E
contains
information
on word process-
ing.
ESCAPE SEQUENCES
Escape sequences,
incorporated
into
a
computer
program,
enable
the
program
to control
terminal
operations.
When
the
terminal
receives
the
escape sequence,
it
performs
the
opera-
tion
specified
in
the
sequence.
Escape
sequences consist
of
most
of
the
operations
performable
at
the
keyboard,
using
the
non-alphanumeric
keys.
Many
sequences
are
also
enterable
from
the
keyboard. References to escape sequences
are
made
throughout
the
manual.
Refer
to
Appendix A for a complete
list
of
the
escape sequences
and
their
functions.
