5.1 Hayes Mode Autodialer
When the Hayes emulation mode is enabled, the Modem emulates a Hayes
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
register S2.)
• Attention Code. AT, the attention code, must begin all command lines.
