Motorola 326X V.34 ユーザーズマニュアル

3-8 Getting Started

To connect the modem to an asynchronous terminal—a terminal without 
software—or a PC running an asynchronous communications software package, 
you use the modem’s AT Automatic Calling Unit (ACU) interface.

The AT ACU is compatible with:

• The industry-standard AT command set (AT and AT& commands)

• The Motorola enhanced AT command set (AT

*

 commands)

AT commands define how the modem is configured, how it makes calls, and what 
test operations it performs. The AT command set lets you configure and operate 
modem options and features from the PC or asynchronous terminal keyboard.

If you are connecting the modem to an asynchronous terminal, you can use the AT 
ACU to configure parameter options from the keyboard. Learn the AT command 
syntax in order to generate the appropriate AT commands.

To continue configuring the modem from an asynchronous terminal, refer to:

• Chapter 4 for configuration instructions.

• Chapter 5 to learn AT command syntax.

• Chapter 6 for a discussion of common problems and how to correct them.

• Appendix A to change configuration options. The Reference Card shows the 

complete menu structure.

(The modem also supports an ITU-TS V.25bis ACU for initiating calls from an 
asynchronous or synchronous DTE, described later in this chapter.)
