TELCOM Applications
In this lesson you will learn how
to
use the Terminal Mode of the TELCOM
application program and the built-in modem to communicate with other computers
over the telephone lines. However, before starting
any
experiments using the Terminal
Mode, it is a good idea to review the overall capabilities
of
TELCOM.
TELCOM Overview
As
you know from reading the owner's manual, TELCOM allows your Model 100 to
be used
as
an automatic telephone dialer (in the Entry Mode), and
to
communicate
with other computers
("host"
systems) over the telephone lines (in the Terminal
Mode). The Entry and Terminal modes may also be used together
to
dial a telephone
number and to
"log-on"
to a system automatically.
In
the Terminal Mode you can access a wide variety
of
information services, including
bulletin boards, news, weather, data banks, other computers or stock market
information. You can make use
of
this information in a variety of ways. For example,
you
may:
• display it on the LCD
• print
it
on a printer
• save it in a file
• analyze the data using a BASIC program
to
graph it, compute statistics, make
comparisons against previous values, and more!
You
can also transfer programs or data files
to
other computers located miles, or even
thousands
of
miles, away.
Before you start using any
of
the features
of
TELCOM, the Model
100
must be
connected to the telephone lines (consult your owner's manual for detailed
instructions).
In this lesson we will assume that your Model
I{j)Q)
is connected to
modular telephone lines using the Modem Cable (26-1410).
Also, we make the assumption that you have access to a computer bulletin board, or a
computer information service (such as Dow Jones or CompuServe).
Contact your local
Radio Shack Computer Center dealer for assistance
in
locating a local bulletin board
if
you cannot locate one on your own.
