Modem Configuration and Commands
What is the Configuration?
The modem configuration is the complete current set of parameter
options, which tell the modem how to function. For example, the
Modulation Mode parameter options specify which mode is used in
data transmission—option 0 for V.34 Auto, and so on.
The modem operates in accordance with:
• The current parameter options
• AT commands, entered from a computer with communications
software
• Network-management commands, received from a Motorola
NMS or Fast’RVu
AT and NMS commands can temporarily override configured options.
Issuing AT Commands
When the modem is in Command Mode or Escape Mode it accepts AT
commands. The modes are similar, but:
• In Command Mode, the modem is not connected to a remote
modem
• In Escape Mode, the modem is connected to a remote modem
Communication between the computer and the modem requires a
common command interface, such as the AT command set. Typically,
you use communications software on the computer, such as
HyperTerminal, and the modem uses its Automatic Calling Interface
(ACU).
AT commands consist of the letters AT followed by characters and
symbols. (The A/ and +++ commands do not include the letters AT.)
Issuing Network Management Commands
You enter network management commands from network management
software. The 3460 Fast’R modem accepts commands from:
• Motorola Fast’RVu software (see Chapter 4)
• Motorola 9000 NMS software (see NMS documentation)
