5.1 Hayes Mode Autodialer

autodialer and functions like a Hayes modem. Commands are issued from

the computer keyboard (or other DTE), and the Modem is compatible with

software written to drive a Hayes style AT command set.

You can enable the Hayes mode autodialer either by using the Quick Setup

feature or by selecting HAYES from the DIALER screen:

• Quick Setup. If you use the Quick Setup feature to select 2-Wire Dial

(Hayes), the Hayes mode autodialer is enabled, and all modem options

are automatically set to a preset configuration suitable for typical Hayes

mode applications. To select the 2-Wire Dial (Hayes) Quick Setup,

access QUICK SETUP screen 1 on the LCD and press pushbutton 2.

• Dialer Mode. If you enable the Hayes mode autodialer using the Dialer

Mode option, no other options are changed. Select DIALER from SETUP

screen 2. Then, select HAYES from the DIALER screen.

The following guidelines for using Hayes compatible AT commands also

provide a summary of the fundamentals of Hayes mode autodialer operation.

Note that although carriage returns are not shown in the examples in this

chapter, a carriage return is required at the end of each command line.

• Escape Sequence (+++). The escape sequence causes the modem to

escape from the data transfer mode so it can interpret commands.

(Alternate characters for the escape sequence can be assigned via S

• Attention Code. AT, the attention code, must begin all command lines.
