Command Line:

Action:

 

 

at&v [ Enter ]

at&w n [ Enter ]

Display current AT command settings and S-register values in the active profile and the two stored profiles (also displays the four stored telephone numbers, which are described in a section of this chapter titled “Number Storage”).

Store the configuration parameters in the active profile to one of the two storage locations, where n represents the desired location and may be 0 or 1.

atz n [ Enter ]

Immediately reset the data module and recall one of the two

 

stored configuration profiles into active status, where n

 

represents the desired profile and may be 0 or 1.

at&y n [ Enter ]

Recall one of the two stored configuration profiles into active

 

status when the data module is powered on, where n

 

represents the desired profile and may be 0 or 1.

at&f [ Enter ]

Recall the factory-default configuration settings into the

 

active profile.

PC Software

Many data communications software packages for use with PCs provide

 

the possibility of writing script or command files. These files can then

 

be run to execute a sequence of commands that will configure your

 

system, or even provide an automatic log on procedure for a particular

 

remote end device.

 

Guidelines for use of some of the more popular software packages with

 

the 7400B Data Module are provided in Appendix C, “Application

 

Notes.”

OPERATING MODES

 

Except when a test condition has been initiated, the 7400B Data Module

 

is always in one of two states: command mode and on-line or data mode.

 

When power is first applied, the data module initializes to command

 

mode.
