If you wish
to use VIDTEX
to communicate with
another
person
who
is
also using VIDTEX
and
a Modem
II, one of
you will have
to set the
MODE Switches to
MAN and
OR1G
(Manual/Originate
Mode) and the
other person will have
to set the switch
to MAN
and
ANS
(Manual/Answer
Mode).
Although it
is up to you and
the person you're
communicating
with
to
decide who
is
to be ORIG
and who is
to be ANS, we suggest
the following
sequence:
1.
Be sure
the FORCE
DTR Switch
on both Modem II's
are set to ON.
2. Both
you
and the
other person should
load
VIDTEX.
3. The
other
person should
set the
Modem II switches to:
_,
o o
ON
OH TR
CD TD
RD
POWER
IN
A
PHI
o
/^~\
4.
You should set your Modem II
switches
to:
POWER
v:
n
i
•^j
5.
You should dial
the other person's phone number.
6. When
the other
person ' s phone rings, he/she should pick up the receiver.
7. The other
person should
set the Modem
POWER Switch
to ON.
Then
both of you will
hear a high-pitched tone and the Modem's RD lights will come
on.
8. Next you should
set your Modem's POWER Switch to ON.
Both CD lights will
illuminate and, after a 2 second delay, the RD lights will
go off.
At the same
time, you both will hear a low-pitch tone.
9. Both you and
the other person should gently hang up the phones.
You can then
begin communicating with
the other person simply by typing on your computer's
keyboards. Your
messages will be displayed on the other person's Screen
and
vice versa.
If you
wish
to see what
you type displayed
on your Screen (and
vice versa),
set your Modem's Test
Switch to
REM. If the other
person also sets his/her Modem's Test
Switch
to REM, you will not
be able to
communicate. Remember!
Only one REMote Test
Switch
on at a time!
