NOTE

COMMUN/CATIONS SOFTWARE

you're

using

computer

rather

than

a terminal,

you

need

communications

software.

Many

brands

are

available, all

which

are

based

the

modem's

command

set.

Some

users

prefer

their

communications

software

take

control

the

modem,

and

are

comfortable

with

program

that

makes

the

modem

almost

transparent.

Others

prefer

program

that

allows

them

use

the

modem's

command

set

some-

times,

and

their

software

other

times,

depending

the

task

hand.

Whichever

you

prefer,

review

least

the

Quick

Start

(Chapter

that

you

have

a basic

understanding

the

modem's

requirements

and

operation.
