Word
Length
—
This
controls how many bits
are in each
character. Most computers use
7
or
8
bits.
Set the word length
by pushing W, then use the CRSR right key
to
make
your selection. Press RETURN when finished.
4. Stop Bits
—
Some computers require
that blank bits be sent
after
each
character,
to signal the end of a character. Normally,
a 300 baud computer gets 8 bits of
data
for
each
character, this
makes a total of ten bits including the start and
stop
bit.Hence,
300
baud becomes
30
characters
per second.
To set the number of stop bits, you press the
S key, use the
CRSR right key to select the number
of stop
bits.
Hit
RETURN
when the proper selection is made.
5. Parity
—
Some computers check for transmission errors
by
setting the highest bit in each character in
a
certain
way. In
even parity, the total number of
"on" bits in each character
should always
be an even number; in odd parity, the number of
"on" bits is odd. Space_parity.always loaves thp highest hit off
and mark parity leaves the bit "on".
I ncorrect parity will
cause
many
of the characters to be printed
incorrectly.
Set
the parity
on
the first
menu page by pressing the P key,
then
use
the
CRSR right key to select the proper parity. Press
RETURN when through.

. Linefeed
—
You press return
at the
end
of a
line,
in order to start
a new line. Some
computers
expect to receive a "carriage
return",
to
start
a
new line. Other
computers expect both a
"carriage return" and a "linefeed" signal. You can select both
signals by pressing L. To choose the "carriage return only
signal"
type C.
