OPERATING INSTRUCTIONS Monitor Functions
transmit/wait decision will be made based comparing a random
number between 0 and 255 to the value of Persist.
If the random number is less than the PErsist value, the channel
is seized. If not, then a delay of SLottime is timed, and the
random number/PErsist calculation is repeated. Thus large
values for PErsist and small values for SLottime produce the
most agressive channel access, and small values for PErsist and
large values for SLottime produce the most civilized channel
access.
Special Protocol Times
You
can
set
up
a
connection
timeout
with
the
command
CHeck,
which specifies a time in multiples of 10-second intervals. This
function
prevents
your
packet
controller
from
getting
stuck
in
a
connection
when
the
other
station
disappears
for
longer
than
the
specified
time.
The
packet
controller
uses
this
time
some-
what
differently
depending
on
the
setting
of
Ax2512v2.
The
command
RESptime
sets
a
delay
between
the
receipt
of
a
packet
and
the
transmission
of
the
acknowledgment
packet.
is
delay
is
used
to
prevent
collision
between
an
acknow-
ledgment
and
another
packet
from
the
sending
station.
This
is
primarily
necessary
during
file
transfers;
otherwise
the
delay
is
est
set
fo
0
(default).
During
file
transfers
the
stations
receiving
the
file
should
set
RESptime
to
10
or
12.
The
timing
of
packet
transmission
in
Transparent
Mode
is
deter-
mined
by
the
command
PACTime.
You
can
choose
the
way
packet
transmission
is
timed.
If
you
are
typing
input
to
a
remote
computer
it
is
usually
best
to
have
packets
transmitted
at
regular
intervals.
If
your
computer
is
operating
a
remote
host
or
bulletin
board
program
you
should
send
packets
after
an
interval
with
no
er
input
from
the
computer.
You
can
enable
the
use
of
PACTime
in
Converse
Mode
with
the
command
CPactime.

Functions

Monitoring
of
packets
not
addressed
to
your
sta
by
the
command
Monitor
ON,
and
separate
monitor
functions
are
individually
enabled.
The
command
MAII
OFF
causes
the
packet
controller
monitor
function
to
ignore
connected
packets.
If
you
want
to
be
able
to

packet
activity
when
your

but
have
all

cease
when
you
connect

someone,
set
MCon
OFF.
To
monitor
stations
selectively,
you
can
set
up
a
list
of
up
to
eight
callsigns
with
the
command
LCAIs.
The
callsigns
in
this
list
are
regarded
as
“buddies,”
i.¢.,
the
only
stations

want
to
