Motorola 3460 ユーザーズマニュアル

3-2

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. 

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.) 

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)
