Sample Command Lines
Two commands are available for recovering from various data
communications problems. You can reset the 7400B Plus and
recall one of two stored profiles as the current configuration. The
form for this command is as follows:
atzn ( )
Enter
where n is the number 0 or 1, representing the configuration
profile to be recalled.
A second command allows you to recall the factory-default
configuration if, for instance, you loose track of changes you have
made and need to start over. The form for this command is as
follows:
at&f ( )
Enter
This section presents a few sample AT command lines for data
calls, along with explanations of the results they will produce.
EXAMPLE 1: Dialing a data call.
AT D T 18006245123 (
CONNECT 2400
In the first line of this example,
AT is the required command prefix,
D is the dial command,
T is the dial modifier for a data call (not required),
and the remainder of the line is the telephone number.
Note: The spaces between the commands and the telephone
number are included only for readability and are not
required. You may also insert hyphens (-) anywhere in
the telephone number for increased readability.
In the second line of this example, the 7400B Plus returns a
response indicating that a connection with the remote end device
has been successfully completed at 2400 bps.
