Getting Started

Option Selection

There are six ways to change or select options:

•AT Commands - The AT command set can be used to select modem options. Chapter 5 describes AT commands.

•Status Registers - A series of special ATS commands allows the operator to change the decimal or hexadecimal value of a memory byte to change one or more options in that byte. Chapter 10 describes S-registers.

•Single Bit Status Registers - A second series of special ATS commands allows the user to change single bits within a byte to change an option. Chapte r10 also explains single bit control.

•Software Program - A wide variety of software programs is available, or advanced computer users can write their own software programs to interact with the modem. This manual does not discuss software programs.

•V.25 bis Commands - An extended set of V.25 commands allows selection of modem options during synchronous operation. Refer to Chapter 11.

Power-Up

A power-up procedure is not required. Turn on the modem using the ON/ OFF power switch on the rear panel. The modem is factory configured to operate in most public switched telephone applications. If you have stored a desired option set it will automatically be restored at power-up.
