Initialization
Many communications programs react to the default settings
when started. This is usually achieved by the ATZ command
and initializes your modem for correct operation. Many
programs are developed for worldwide use and generally
use the ATZ command; however, some programs have built-
in modem configuration utilities and these should not be
used unless you can confirm that they are compatible with
Australian and New Zealand requirements.
If your program does not use the ATZ command to initialize,
but instead sends a complex string of characters, then it must
be configured to send the correct string for Australia and
New Zealand. The correct initialization string is (spaces
should not be entered; they are to make it easier to read):
AT &F T /N6 S6=3 S7=45 % L=7 &Y0 &W0
Once you have entered this command string, it is written to
the internal memory of the modem and the default
configuration.
Dialing
The modem supports both pulse and tone dialing in
Australia and only tone dialing in New Zealand.
New Zealand users please note that if pulse dialing is
selected, then wrong numbers will be dialed, as the reverse
numbering scheme is not supported. There are several dial
string modifiers referred to in the main users' manual, and
we suggest that they be used with caution to avoid problems
when making calls.
Automatic Answering
To conform with Austel and Telecom New Zealand
requirements when configuring your modem for auto-
answering, please do not set the SO register to values less
than 2 or greater than 10 (Note: ATSO-O will disable auto-
answering). Pre-configured software should be checked and
changed as necessary. These settings ensure:
A person calling your modem will hear a short burst of
3
ringing before the modem answers. This confirms that the
call has been successfully switched through the network.
Caller identification information (which occurs between
3
the first and second ring cadences) is not destroyed.
