OPERATING
INSTRUCTIONS
Multiple
Connections
Only packet controllers
termed "DUAL
PORT’ in the TECH-
NICAL
REFERENCE
MANUAL
are capable
of simultaneous
operation
of the radio ports. Dual-radio
or dual-modem
models
disconnect
the port not currently
selected.
Some PacComm packet controllers aliow selection of the carrier
detect signal (DCD) from either the modem circuit (hardware)
or asoftware algorithm (software). The command SOftded ON
selects the software type of DCD, while SOftded OFF selects
the hardware signal for DCD. Consult the TECHNICAL REF-
ERENCE JAL to determine if this command applies.
Multiple Connections
With
multiple
connections,
you
may
establish
simultaneous
connections
with
several
stations,
and
the
packet
controller
will
keep the data to and from each connection segregated. The
packet
controller
defaults
the
multi-connect-related
parameters
to
the
following
’single
connection’
values:
CONPerm OFF
LCStream
OFF
STREAMCALI
OFF
STREAMDbI OFF
STReamswitch
|
USers 1
The
key
to
enabling
multiple
connections
is
to
set
USers
to
a
value
greater
than
1.
If
USers
is
not
1,
the
packet
controller
will
allow
multiple
connections
(as
many
as
the
value
of
USers)
to
your
station
from
other
stations.
In
addition,
Transparent
mode
will
operate
differently,
in
that
incoming
data
will
be
prefixed
with
the
current
STReamsw(itch)
character
and
identifier
(such
as
“|
A”).
Thus,
truly
transparent
operation
is
not
possible
while
supporting
multiple
connections.
The
STReamsw(itch)
character,
defaulted
to
“|”,
should
be
set
to
a
character
you
won't
normally
use.
Note
that
this
character
may
be
set
to
a
hex
value
between
$80
and
$FE.
This
may
allow
you
to
use
8-bit
characters
(AWlen
8)
if
your
terminal
or
com-
puter
is
capable
of
generating
such
“characters.”
This
could
help
prevent
confusion
in
interpreting
incoming
data
from
other
stations
if
they
happen
to
send
data
that
includes
your
selected
STReamswitch
character.
When
operating
a
single
user
Mail-
Box
(BBS)
system
or
other
host
computer
application,
it
is
ated)
recommended
that
STReamsw(itch)
be
set
to
$00
(dis-
abled).
Although
not
foolfproof,
enabling
STREAMDb!
may
also
help
in
sorting
out
STReamswitch
characters
included
in
the
Operating
