PacComm TINY-2 - Advanced Operations and Systems

OPERATING
INSTRUCTIONS
Special
Operations
For
satellite
and
other
full
duplex
modes
of
operation
you
should
set
DWait
to
0.
The
random
wait
before
retry
transmis-
sions
can
be
disabled
by
setting
TXDelay
0
and
ang
Oand
using
AXDelay
to
set
the
required
keyup
delay.
Computer
Operations
The
BBsmsgs
command
is
particularly
useful
when
the
packet
controller
is
used
with
a
host
computer.
When
ON,
the
com-
mand
causes
all
packet
controller
messages
to
either
be
supressed
or
to
begin
on
a
fresh
line.
The
RXblock
command
should
be
used
when
the
packet
con-
troller
is
serving
a
host
computer.
RXblock
is
designed
for
automated
operations,
such
as
packet
bulletin
board
stations.
It
is
intended
to
help
such
systems
discriminate
between
data
received
from
the
connected
station
and
packet
controller-
generated
messages.
If
unacknowledged
data
packets
exist
at
the
time
of
a
disconec-
tion,
the
packet
controller
will
send
all
of
these
data
packets
as
Unnumbered
Information
(UI)
frames.
To
prevent
the
dumping
of
itlese
frames
over
the
air,
set
the
command
TXUIfram
to
The
STATus
command
is
useful
for
allowing
a
host
computer
to
obtain
information
about
whether
a
connection
exists,
whether
there
are
any
unacknowledged
frames,
and
whether
a
pending
connection
or
disconnection
exists.
HF
Operation
Some
PacComm
packet
controllers
are
equi
ed
with
both
VHF
and
HF
optimized
modems.
See
the
CAL
REF-
ERENCE
IAL
for
a
description
of
your
controller’s
capabilities.
Dual-modem
boards
have
several
additional
com-
mands
to
support
HF
operation.
The
POrt
command
selects
which
radio
port
is
in
use.
The
POrt
command
causes
most
parameters
except
callsign
to
be
changed
to
correspond
with
the
use
of
the
selected
port,
including
the
radio
baud
rate,
modem
tones,
and
link
timing
parameters.
If
the
POrt
command
is
given
without
an
argument,
the
packet
controller
responds
with
the
number
of
the
currently
selected
port.
If
POrt
is
given
followed
by
a
port
number
such
as:
cmd:
PO2
the
packet
controller
switches
to
the
specified
port
and
responds
with
the
number
of
the
previously
selected
port.
