Getting Started
Option Selection
There are six ways to change or select options:
• LCD - Using the front panel LCD and pushbuttons is simple,
straightforward, and requires the least amount of technical
background. Chapter 4 explains LCD operation.
• 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.
