Serial Port parameters
If net from your packet controller appear garbled, with
incorrectly ceplned characters, you may need to change the
parity
and
word
length
of
either
the
computer
terminal,
the
acket
controller,
or
both.
The
most
common
parity
and
word
ength
combinations
are
8
bits,
ne
pee
the
packet
controller
default),
and
7
bits,
even
parity.
The
packet
controller
default
will
probably
be
accepted
even
if
your
computer
actually
uses
the
latter
setting.
If
your
computer
receives
8
bits
as
data,
you
may
have
to
set
space
parity,
since
text
may
otherwise
be
inter-
preted
as
graphics
or
other
special
characters.
To
set
7
bits,
space
arity,
use
the
combination
immediately
below.
To
return
to
7
its,
even
parity,
set
the
second
combination:
AWlen 8 (8-bit words) AWlen 7 (7-bit words)
PARity 0 (no parity bit) PARity 3 (even parity)
One
of
these
combinations
will
satisfy
most
computers.
You
are
more
likely
to
require
a
different
setting
if
you
have
a
terminal
rather
than
a
computer,
or
ifyou
have
configured
your
terminal
port
for
some
special
application.
If
your
computer
requires
odd
parity,
set
PARity
1.
If
your
computer
detects
framing
errors,
try
one
of
the
following
settings:
For
shorter
characters.
For
longer
characters
AWlen
7 (7-bit
words)
AWlen
8
(8-bit
words)
