Command Mode
If you turn on your computer and start communication by a communication
program, you can see a prompt on the terminal screen. Under such conditions,
you can use
AT commands like calling, etc.
DATA Mode
In command mode, you can call by using AT commands and communicate with
others by connecting to other modems. You can call this status Data mode or On-
line mode. In data mode, you cannot use any AT commands except the +++
command, which has +++ at the head.
If you stop communication and disconnect the phone, the Fax modem will run in
command mode again.
Using Command Mode during Communications
Sometimes, you have to use AT commands while you're communicating with
others via modem. In this case, you can use +++ commands for AT commands
without hanging up your telephone. Pressing '+' three times makes fax modem
change to command mode. The telephone will not be disconnected. (Do not press
the [Enter] key after input +++).

If you want to return to Data Mode, the connection may be lost depending
on the server.
If you want return to Data mode from command mode, you only have to input ATO
and press the [Enter] key to start the communications again.

The mode cannot be transferred from the command mode to the data mode

Using AT commands
AT commands can be used in the following way. There's no difference between
capital letters and small letters, and all commands should include 'AT' as a prefix
except ones which include 'A/' instead.
Also, Carriage Returns saved in the S3 register should be entered in order to
signal the end of the command.
AT command - press the [Enter] key.
Example: ATDT 123-4567 - press [Enter] and the modem dials to 123-4567.
