Only a few basic commands are enough for computer communications. BeforeUsingATCommands AT commands can be used by entering them into terminal-based communication programs directly. (Hyper terminal, CrossTalk, Procomm, etc.) CompuServe, America On-line applications are not terminal-based communication programs, but they are the communication programs based on a Graphic environment. This kind of program can initiate the modem setting by entering AT commands in a menu having a modem initialization command. What you have to know before using AT commands is that there are two kinds of modes when you use it. 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. Troubleshooting 81 In data mode, You can't 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 command while you're communicating with others via modem. In this case, you can use +++ command for AT command without hanging up your telephone. Pressing '+' three times makes fax modem change to command mode. Of course, the telephone is not disconnected. (Don't press the Enter key after input +++) 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 can not be transferred from the command mode to data mode depending on the server. UsingATCommands 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 Return saved in the S3 register should be entered in order to sign the end of the command. AT commandPress Enter key Example: ATDT 123-4567Press Enter and the modem dials to 123-4567 Display the result value After entering AT commands, the result value is displayed on the screen. The result value can be displayed during communication. Generally, the result will be OK. According to the ATV command, the result can be displayed as Words or numeral letters. (ATV0: Display as numeral letters, ATV1: Display as English words) 82 UsersManual BasicATCommands A/ Repeats the previous command in the buffer ATA Responds manually to incoming RING signals +++ Switches from on-line mode to command mode ATO Switches from command mode to on-line mode ATEn Echo control E0 Disables echoing of the commands to the screen E1 Enables echoing of the commands to the screen ATDT phone numberTouch tone dial ATDP phone numberPulse dial ATHn Hook control H0 On-Hook (same as hang-up) H1 Off-Hook (same as hold-on) ATLn Modem speaker loudness control L0~1 Low volume L2 Medium volume L3 High volume ATMn Modem speaker control M0 Disables modem speaker M1 Enables only when in connection procedure M2 Enables always M3 Enables until carrier has been detected after connection ATS0=n Sets S0 register value (n range: 0~255). Sets the number of incoming ring signals before answering. Modem responds after ringing as many times as specified in n value. If the value of n is '0', ATA command should be entered for auto answer ATS0? Displays S0 register value on the terminal ATX3 Dials after waiting for specified time Troubleshooting 83 ATX4 Dials after dial tone is detected ATZ Initializes modem AT&F Loads the factory default configuration (profile) AT&V Shows current configuration AT&W Saves user profile AT&Zn=x Stores the dial string in modem memory (n=0~3, x=phone number) e.g.) AT&Z0=1235678 Automatically calls the stored phone number by using the following command. ATDTS0Recalls the stored phone number as AT&Z0 by tone dial ATDPS0Recalls the stored phone number as AT&Z0 by pulse dial AT+MS=X Sets protocol for modem connection (X=V90, V34) AT+MS=V90 (default setting) Try to connect with V.90 (max 56 Kbps) AT+MS=V34 Try to connect with V.34 (max 33.6 Kbps) 84 UsersManual Windows Me LAN Driver (Re)Installation Before you begin verify that the “Samsung SEM-2100iL MiniPCI LAN Adapter” is installed otherwise you will have to install it.
