Baud Rate Selection
Transmission rates are switch-selectable
at
the
rear of
the
terminal.
The
baud rate switch
has seven positions 1,
2,
4,
8, 16,
32,
and 64.
The
baud rate multiplier switch has two positions;
110
times
or
150
times. The selected position
causes
the
selected baud rate
to
be
multiplied
by
11
0
or
150. The switches produce rates
of
150,
300,
600,
1200,
2400,
4800,
and
9600
baud for 10-bit word operation; or 110, 220,
440,
880, 1760,
3520
and
7040
baud for 11-
bit word operation.
1.3.2 Operating Modes
The SUPER
BEE
Computer Terminal
normally operates
in
one
of
three modes;
the
Character mode,
the
Program Entry mode, and
the
Format mode.
In
each mode,
the
SUPER
BEE can
be
operated either on-line
or
off-line.
Character Mode
Character mode
is
selected upon power-
on
or
depression
of
the
RESET key.
In
this mode,
the
monitor
displays all characters and reacts
to
all control codes. Depression
of
RESET key auto-
matically returns
the
terminal from any
other
mode
to
Character mode.
Character Mode (Off-Line) - Characters entered
from
the
keyboard are stored
in
the
terminal '
memory and displayed
but
not
communicated
to
the
1/0 port. Control
and
escape sequence
codes are
dependent
upon appropriate strapping.
Characters received
at
the
1/0
port
are ignored.
Character Mode (On-Line) Characters entered
from
the
keyboard are transmitted from
the
1/0
port
as
they
are entered.
If
operated half
duplex {HDX),
the
characters are stored
in
the memory and displayed as
they
are entered.
When operated full duplex {FOX),
the
char-
acters are transmitted
to
the
1/0
port
only,
and are stored
in
the
memory and displayed
if
a remotely connected data source echoes
each transmitted code.
1-4
Program Entry Mode
A Program Entry mode
is
selectable
from
the
keyboard
or
from a remote data
source intiated by an escape sequence code.
When
in
the
Program Entry mode,
the
ter-
minal does
not
respond
to
control and es-
cape codes,
but
stores these codes
in
mem-
ory
and displays their associated character
or
symbol.
NEW
LINE and ENTER functions
are exceptions. They are displayed
in
normal
video and acted upon. The Program Entry
mode
is
intended
to
display control characters
and escape sequence characters prior
to
transmission
or
after receipt
of
a transmission
Programming from
the
terminal
is
made poss-
ible through
the
implementation
of
the
Program Entry mode.
Program Entry Mode (Off-Line)- Characters
entered from
the
keyboard are stored
in
the
terminal memory and displayed
but
not
transmitted
to
the
1/0 port. Control codes
are displayed as special symbols and are
not
acted upon, with
the
exception
of
NEW
LINE and ENTER. Escape function char-
acters are displayed
in
reverse video and
are
not
acted upon.
Program Entry Mode {On-Line)· The ter-
minal operates
the
same
as
that
for
the
Program Entry mode {off-line), with
the
exception
that
data entered from
the
key-
board
is
transmitted
to
the
1/0 port. The
transmitted control escape and sequence codes are
dependent upon appropriate strapping.
Format Mode
A Format mode
is
selectable from the
keyboard
or
from a remote data source initiated
by an escape sequence code.
In
the
Format
mode,
the
terminal display has protected fields
in
which the cursor can
be
positioned,
but
no
data may be entered.
If
desired, unprotected
fields may
be
delimited by use
of
brackets
or
reverse video
to
indicate
the
area for data entry.
Format Mode (Off-Line)- Characters entered
from
the
keyboard are stored
in
the
unprotected
locations
in
the
terminal's memory and displayed
but
are
not
