Selecting Programmed Option Sets

Option sets make it easy to use a modem with common applications, including:
Four sets of options are stored in nonvolatile memory. If none is appropriate to an
application, you can customize an option set, and save it in nonvolatile memory.
Refer to Chapter 4, Configuring the Modem, for more information on option sets.

Automatic Calling Interfaces (ACUs)

The modem supports three automatic calling interfaces (also known as Auto-Call
Units). ACUs let you execute functions directly from a keyboard.

AT ACU

The asynchronous AT ACU is compatible with the industry-standard AT command
set. AT Commands provide a standard modem communications interface, allowing
you to configure and operate your modem from a terminal or PC keyboard.
Using the AT-compatible command set (AT and AT&), you can, for example, dial
and receive phone calls. Motorola's extended AT command set (AT
important parameters used in configuring advanced modem features.
Refer to Chapter 3, Getting Started, and Chapter 5, Using the AT Automatic Calling
Interface, to learn more about the AT ACU and AT command syntax.

V.25bis ACU

For sync or async auto-calling, use the ITU-T V.25bis compliant ACU.
With either the AT or V.25bis ACU, you can store, dial, or change up to nine phone
numbers in the modem's electronic telephone book, directly from your terminal.
Refer to Chapter 3, Automatic Calling Interfaces, in the 326X Series Modem
Reference Guide, for details.

LPDA2 ACU

The LPDA2 feature lets you use IBM dial and leased line restoral applications with
LPDA2 Dial and Disconnect commands. LPDA2 allows Netview and other IBM
applications, like POS outbound dialing applications, to control dialing.
In dial applications, LPDA2 eliminates the need for additional ports and equipment
that had been required to support external 801 auto-dialing equipment in IBM
environments.
