AT Command Set Result Codes Example
Other Important Settings
The modem supports an extended Hayes AT command set that allows you to adjust the modem's operating parameters and initiate calls. This chapter describes how to operate the modem from a personal computer or a terminal keyboard using AT commands.Functional States
In AT command operating environment, the modem has four functional states:The command state,
The wait-for-carrier state,The on-line state, and
The on-line command state.
In the command state, the modem accepts AT
commands form the terminal, allowing you to configure the modem and dial telephone numbers. When the
modem is powered on, it defaults to the command state.After modem dials a number, it enters a transition state,called the wait-for carrier state and waits for a carrier signal from the remote modem. If the modem does not detect a carrier signal within a preset time period (this period is defined by the value of S7 register), it
abandons the call and re-enters the command state.You can also cause the modem to exit the wait-for-carrier state and return to the command state by
pressing any key on the keyboard, causing a dial abort action.
If modem detects a valid carrier signal, it connects with the remote modem, according to the best negotiation speed decided by both modems, and enters the on-line state. In this case, the modem transmits data asynchronously. If the carrier signal is lost or
intentionally dropped the connection, the modem hangs up and re-enters the command state.
While the modem is on line, you can temporarily exit the on-line state, and enter the on-line command state, from which limit set of AT commands can be entered to interrogate the modem current settings and make sure the connection is what is supposed to be and to disconnect the line gracefully.
To enter the on-line command state, wait 1 second, type +++, wait another 1 second, and type AT, carriage return (this procedure is called Time Independent
Escape Sequence, TIES). The first valid AT commands entered while the modem in the on-line command state will be executed just as they would be executed in the command state. If the first command is Invalid in this state, it will cause modem be to on-line state and you will have on-line connect message shown on the screen.
After the first command is accepted and in the on-line command state, the rest AT commands will accepted with OK or rejected with ERROR and stay in this state until
1. You issue ATO command to re-enter the on-line
state,
2. You issue ATH to drop the connection and back to
command state,
3. Connection is disconnected and the modem go
back to command,
4. Application program request modem to disconnect
and go back to command state.Configuration Profiles
A configuration profile refers to a complete set of operation parameters for the modem. The operating parameters in use at any one time are referred to as active profile. The active profile is stored in RAM in the modem and it may be viewed by entering AT&V. Each time the modem powers up, the active profile is loaded with profile 0 or 1 at the time modem was last powered off
You can store the active profile into profile 0 or profile 1and into the non-volatile memory (EEPROM) by
entering AT&W0 or AT&W1. So next time the modem is powered up, you can assume the profile while you left off.

The factory default profile, which is stored in ROM in the modem, consists of the operating parameters most commonly used for data communication and is
satisfactory for the needs of most users. The default profile can be reload into active profile by entering AT&F9.
AT Command Syntax
With two exceptions, all AT commands are prefixed with AT (uppercase or lowercase, even, odd, none, mark or space parity do not matter), which stands for "ATtention", command body, list in the following
sections, and command line terminator, most commonly used is carriage return.
The two exceptions are the "A/" command, which is used to repeat the last command, and the "+++", which cause modem goes into on-line command state.There are 40 characters length limitation post on every single command line. Any command line exceeds this limitation will result an ERROR result.
