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 data module returns a response
indicating that a connection with the remote end device has been
successfully completed at 2400 bps.
EXAMPLE 2: Dialing a telephone number outside your PBX domain with a
few other options thrown in.

In the first line of this example,
at is the required command prefix,
●
● &f tells the data module to restore the factory-default configuration
parameters,
● d is the dial command,
● 9 represents the access code required to dial a number outside your
PBX domain,
● and the remainder of the line is the telephone number.
In the second line of this example, the data module indicates that it detected a
busy signal.
EXAMPLE 3: Using a time saver.
A/
The A/ command tells the data module to repeat the last command line
exactly. If, as in the previous example, you had issued the command to dial a
number and the data module returned the message BUSY, you could type the
A/ command to try the number again.
Note: The A/ command must be the only command on the command
line, and you do not press [ Enter ] to complete the line.
