view these parameters, the communication port status and settings,
and the DART 200’s S-Registers use the AT&V

command, for

Most S-Registers are used by the DART control program. The
S-Registers of interest to the end-user are discussed in the following
sections.

3.

Set Side Preference with AT\Nn. This command specifies which
service provider side (A or B) to search for a usable CDPD channel.
In each geographical area, there is a maximum of two service
providers (an A side carrier and a B side carrier). Your carrier sets up
this value or provides you with their preference. The default is \N3
(A side preferred), but is not appropriate for most end-users. If you
have an A side carrier, enter

AT\N1

; if the carrier is B side enter

AT\N2.

4. Verify that there are no channel restrictions in place. These

restrictions are controlled by the \Jn parameter. The default value is
\J0, no restrictions, and is the desired setting. If this parameter has a
non-zero value from prior use, set it to zero with

AT\J0

before

proceeding.

5. Save your changes into permanent memory with the

AT&W

command. Issue this command after making the above changes to
ensure that new values replace the default values.

6. Display the modem profile using the AT&V

command to check that

your change to the \N parameter was successful.

The basic setup for your CDPD modem is now complete.
