    Installing The CheetahModem Internal PCI Checking Your Components Unpack your CheetahModem and make sure you have the following items: The CheetahModem. A modular telephone cable to connect your CheetahModem to the telephone line. Communication software (included driver and manual) When you open your package, make sure all of the above items are included and not damaged.

  • Page 8: Installing The Cheetahmodem

    Installing The CheetahModem The following instructions explain how to install the CheetahModem into a PC computer. If you will be installing the CheetahModem into a different computer, refer to the manual that came with your computer or contact your computer dealer for instructions.

  • Page 9: Connecting To The Telephone Line

    Connecting To The Telephone Line Use the following procedure to connect your CheetahModem to the telephone line: Locate an available RJ-11 modular jack telephone outlet. Take one end of the modular cord supplied with the CheetahModem and plug it into the LINE modular jack on the back of the CheetahModem. Plug the other end of the modular cord into the modular jack on the wall outlet, as you would any modular telephone.

  • Page 10: Verifying Your Connection

    Verifying Your Connection Start a communication program and place the computer into terminal mode. Refer to your computer manual to find out the appropriate command to do so. Then use the following procedure to verify your installation: Type AT[Enter] If your system is operating properly, your CheetahModem sends an OK response to your screen and waits for your next command.

  • Page 18: Tips On Configuring Your Communications Software

    Tips On Configuring Your Communications Software Your CheetahModem uses the most up-to-date industry and commercially popular standards to ensure functional compatibility with most communication software. During initial set-up of the communication software, it will normally prompt you to define the type of CheetahModem you are using. The following is a general guideline for the device type you should choose.

  • Page 19: Executing Commands

    Executing Commands If you will be using a communication software program to make data calls, you will probably not need to type commands, because your software program will handle this for you. Similarly, you will probably not see the responses because your software program may intercept them. However, if you perform data activities directly with your CheetahModem, you will find the format for typing CheetahModem commands and fax/ modem response helpful.
  • Page 20 The A/ command need not be prefixed by the 'AT' characters or followed with the [Enter] key. If a command requires a parameter such as 0 and 1, the parameter is identified as n in the left column and described in the right column. IMPORTANT: Each command, except for '+++' and 'A/', must be preceded by 'AT' and executed when you press the [Enter] key.

  • Page 21: S Registers

    S-Registers Your CheetahModem has S-registers that affect various operating characteristics. The registers let you obtain information about the CheetahModem, and let you test the CheetahModem. Each S-Register has a factory-set value, which you can read or change to fit your particular requirements.

  • Page 22: Response Sets

    Response Sets When you send a command to your CheetahModem, it sends a response to your computer. For example, if you type AT[Enter], the CheetahModem should respond with OK. The CheetahModem gives out different responses for the different tasks that it performs. Communication software use these responses to control the flow of the program.

  • Page 46 one ringback has been detected)in 100 ms units. AT#VRN Ringback Never Came Timer(Originate) This command can be used when originating a voice call(#CLS=8)to set the "Ringback Never Came" timer value, i.e., an amount of time (in units of 100 ms) measured from completion of dialing. If ringback is not detected within this period, the modem assumes the remote has picked up the line and switches to Online Voice Command Mode.
  • Page 47 ERROR Otherwise Command options: #VSK? Returns the current setting of the #VSK command as an ASCII decimal value in result code format. #VSK=? Returns the message,"255". #VSK=n n defines the 255 unused bytes remaining in the modem voice transmit buffer after an XOFF is sent to the DTE. AT#VSP Silence Detection Period (Voice Receive) This command sets the Voice Receive Mode silence detection period (inactivity timer) value.
