OPERATING
INSTRUCTIONS

Some
computers
will
lose
the
first
characters
of
a
line
when
several
lines
are
typed
in
rapid
succession,
for
example,
in
the
sign-on
message.
You
can
give
the
computer
more
time
between
lines
by
setting
NUer
ON
(delay
after<CR>),
or
NULf
ON
(delay
after
<LF>).
The
amount
of
delay
is
eave
by
NULLs,
which
sets
a
number
of
character-times
for
the
delay.
You
may
see
two
characters
on
your
screen
for
every
character
you
type,
for
example:
emd:EECCHHOO
In
this
case
your
computer
is
echoing
the
characters
you
type,
and
the
packet
controller
is
also
echoing
them.
Set
Echo
to
stop
the
packet
controller’s
echos.
If
you
later
use
your
packet
controller
with
a
different
computer,
or
different
terminal
pro-
gram,
and
nothing
is
displayed
when
you
type,
set
Echo
ON.
If
the
packet
controller’s
sign-on
message
lines
appear
to
be
typed
over
each
other,
you
should
set
AUtolf
ON,
If
the
packet
controller’s
sign-on
message
appears
to
be
double-spaced,
you
should
set
AUtolf
OFF.
If
the
packet
controller’s
sign-on
mes-
sage
appears
to
be
single-spaced,
you
have
AUtolf
set
correctly.
If
you
change
equipment
you
may
have
to
set
AUtolf
ON
to
restore
the
packet
controller’s
automatic
linefeeds.
If
you
are
able
to
enter
one
command
successfully
and
then
een
receiving
the
27unknown
command
message
set
LF
Ignore
ON,
or
set
re
computer
terminal
to
send
only
a
<CR>
when
the
ENTER
key
is
pressed.
If
you
make
mistakes
while
entering
commands
to
the
packet
controller,
you
can
make
corrections.
To
erase
the
last
character
you
typed,
enter
a
<
BACKSPACE
>
character.
The
packet
controller
will
throw
away
the
last
character
you
typed
(nice
you
are
at
the
beginning
of
a
line)
and
try
to
erase
the
character
from
your
screen.
Input
editing
will
be
discussed
in
more
detail
in
the
section,
“Special
Input
Characters.”
The
screen-width
parameter
(Screenin)
defaults
to
0,
since
most
computers
automatically
insert
a
<CR
>
to
format
lines
to
the
screen
width.
If
Screenln
is
non-zero
the
packet
controller
will
send
an
extra
<CR>
(or
<CR><LF>
if
AUtolf
is
ON)
when
the
Screenln
number
of
characters
have
sent.
If
your
computer
does
not
automatically
break
long
lines,
you
will
need
to
set
Screenin
to
the
width
of
your
display.
For
example,
using
a
TV
set
for
a
display,
you
would
set
Screenin
to
23
or
40.
Some
PacComm
packet
controller
models
have
a
BAud
com-
mand
for
changing
the
terminal
(and
radio)
data
rates,
while
other
models
use
switches
or
hardware
jumpers.
