Using The At Automatic Calling Unit (Acu); Using The Modem With An Async Terminal - Motorola 326X V.34 User Manual

Using the AT Automatic Calling Unit (ACU)

To connect the modem to an asynchronous terminal—a terminal without
ATZ4 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:
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.

Using the Modem with an Async Terminal

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:

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