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.
