The US Robotics Courier 2400 High Speed Modem
A Product Evaluation
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
When first scanning the Courier documentation, the first statement of the
manual reads like this:
CONGRATULATIONS! You have just purchased the US Robotics Courier 2400
modem, one of the most advanced communications devices in the world.
Whether you are a seasoned modem user, or have just purchased your 1st
modem, we are sure that it will give you excellant service.
Now, I know when a company makes a promise like that it tends to make a
buyer wary, knowing that most claims in the computer world tend to be just
a shadow of the actual ability of the product. With the Courier, exactly
the opposite is shown to be true. This modem not only delivers everything
that it promises, it gives even more! In this evaluation, I hope to walk
you through the world of the Courier 2400, and give you the pros and cons
regarding this purchase.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Documentation:
The documentation for this product sets the stage for overall excellance
in the Courier 2400. It is equally usable by either a novice or pro, and
will give you the background necessary to begin your trek into the world of
high-speed communications.
The manual is organized into 2 logical setions, the first dealing with
the installation and usage of the modem, and the second dealing with the
more technical aspects of telecommunications.
The first section is divided into three chapters. Chapter 1 is an intro
to the Courier 2400 and gives the operational requirements of the unit.
Chapter 2 deals with setting up and testing your new modem, and also has
a description of the contents you should receive with the modem.
Chapter 3 deals with the actual operation of the modem.
The second section, reference, deals with the facts that are needed for
more technical applications. These include definitions of the RS-232 inter.
and the pin descriptions, a summary of the DIP pin settings, an alphebetical
command summary, and a "problems and solutions" section which is included in
hopes of cutting down on modem "down" time. It also includes a glossary of
frequently used terms in tele-communications and an index.
With this docementation, it is possible for a beginner to go from setting
up the modem to actually communicating in less than 1/2 hour. I believe the
documentation to be one of the major victories of the modem, and feel that
this adds the "icing on the cake" to this product.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Operation :
The Courier fully supports the use of the standard "AT" command set and
the company even goes so far as to consider Hayes "USR compatible". This is
a strong claim to be made, but this product fully backs up this claim. One
of this modems strong points, for beginners, is the inclusion of onboard ROM
which has 2 help screens built-in. The first help screen deals with the AT
command set, and the second deals with the "S" registers of the modem. These
help screens will be highly beneficial to either a beginner or to someone who
is not familiar with the Hayes standard.
Not only does the Courier fully support the full "AT" set, but it also adds
several features such as "adaptive" dialing, which includes such features as
the ability of the modem to detect busy signals, non-data answers, and the
type of line (pulse or tone) that it is connected to. It also has the ability
to "reverse" originate/answer mode, so as to allow the communication with a
modem that does not support auto-answer. It also supports the use of "alpha"
dialing, that is, if you have a number such as "301-IBM-NEWS" you can enter
it into the dial command, and the Courier will automatically convert the alp.
characters into numeric form.
The modem also supports 4 different speaker settings:
1.) Disable speaker entirely
2.) ON through dialing and Carrier detect, OFF at connect
3.) ON continuously, including data transmission
4.) ON after last digit dialed, OFF at connect
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Summary :
As you can probably tell from the preceeding text, the Courier 2400 is the
most innovative new products to come out in years. The nicest feature of this
modem is its price, only $695.00. When you consider that a new 1200 baud mo
modem is selling for $450.00, you can see why the Courier 2400 is a steal.
