Running
the
COMM
Program
A sample telecommunications program
is
also provided
on the DOS Diskette. This program lets
you
establish
an asynchronous communication link between
your
IBM
Personal
Computer
and
another
IBM
Personal
Computer, an
IBM
Series/1 computer,
or
two
communications network services.
This means
that
your
computer
can
"talk"
to
another
computer
or
be
part
of
a
network
service. You can
imagine
that
the computers are talking
on
the
telephone to each other. (Using a network service
is
like being on a
"party
line.")
The
COMM
program will work "as is"
if
you
have the
necessary
option
(Asynchronous Communications
Adapter), equipment, and subscriptions.
(For
a
description
of
the adapter
you
need, see the
"Asynchronous Communications
Adapter"
in Section 5
of
this binder.)
For
assistance with interfacing with
external devices, consult
your
point
of
sale.
You could also use this sample program
as
the model for
writing
your
own telecommunications program.
Let's look
at
the
COMM
program
menu-you
can do this
even
if
you
do
not
plan
to
communicate with
another
computer. Do this:
1 Make sure Disk BASIC
or
Advanced BASIC is running
and
Ok
is
displayed.
2 Insert the DOS Diskette into drive A:.
3 Type this:
load
"comm
and press the Enter key.
4 Type this:
run
and press the
Enter
key.
