- 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.
