This
is
known
as
a
three-wire
interface
and
therefore
requires
the
use
of
software
flow
control.
This
cabling
supports
the
TRS
VIDTEX
program.
If
you
have
a
micro-color
computer,
such
as
the
MC-10,
cabling
is
different;
consult
your
computer
reference
manual.
You
may
also
use
the
Radio
Shack
Deluxe
RS-232
Program
Pak.
This
is
a
plug-in
module
for
the
TRS-80
Color
Computer
line
which
is
available
from
Radio
Shack
Stores.
The
Deluxe
RS-232
Pak
has
a
standard
DB-25
serial
port
connector
to
which
you
connect
the
TNC
using
the
following
pin
configurations:

You
must
also
install
a
jumper
between
pin
8
and
pin
20
on
the
DB-25
connector
of
the
Deluxe
RS-232
Pak.
It
is
not
necessary
to
connect
RTS/CTS
lines.
Since
these
lines
are
not
connected,
you
must
use
software
flow
control.
Configure
the
Deluxe
RS-232
Pak
as
outlined
in
its
operation
manual,
select
the
Terminal
Mode
and
you
will
be
ready
for
packet
operation.
TRS Model-100
This
computer
has
a
standard
RS-232
serial
port
using
a
DB-25
connector
wired
as

The
internal
modem
program
DOES
NOT
support
CTS/RTS
hardware
flow
control.
Be
sure
to
have
the
TNC
command
XFLOW
ON
so
that
software
flow
control
(XON/XOFF)
will
be
used.
