Defining a Dialer Script
Introduction
The first step in configuring a dial service is creating a dialer script. A dialer script tells
the access server what text strings to use to control a modem on a specific port. These
text strings are also known as “modem strings.”
Defining Dialer Script Strings
Use the SET, DEFINE, and CHANGE DIALER SCRIPT commands to define the
modem strings that make up various modem commands in a dialer script. Each
associated string can be up to 40 characters in length.
Characteristics that you set using the DEFINE command take effect after you initialize
the access server. Characteristics that you set take effect immediately, but are replaced
when the access server initializes. Characteristics that you set using the CHANGE
command take effect immediately and when the access server initializes.
The size of the dialer script modem strings is restricted by the amount of remaining
unallocated NVRAM for the modem pool (total of 256 bytes for 8 and 16 port servers,
and 512 bytes for 32 port servers) and by the command line restrictions. The script
name can be a maximum of 16 characters.
Dialer String Descriptions
The following table lists the dialer script strings you can define, their default values
and usage:
String Type Default Value Usage
COMMAND "AT" Appended to all other command strings.
INIT None Before initiating an outbound
connection.
PREFIX "DT" Before digits of phone number.
CONNECTED "CONNECT" Verifies successful connection.
RESET "H0Z" After session is disconnected.
