5 Hints for Good Connections USING THE MODEM Use the following information when you set up your communications software to help your modem connect at the highest possible speed: ■ If you have call waiting, disable it. Call waiting generates a tone on the line that causes results similar to static. It also causes your modem to disconnect or report NO CARRIER if a call waiting signal comes when your modem is connected to another modem.
26 CHAPTER 5: USING THE MODEM For most applications, you can use the factory-default setting for the modem initialization string. To reset your modem to the factory defaults, use the AT command string AT&F. For more information, see “S Registers” on page 32. Making a Call with HyperTerminal HyperTerminal is the resident telecommunication application supplied with Windows 95 and Windows NT 4.0. This section shows you how to place a call using HyperTerminal.
Additional Modem Features Additional Modem Features 27 ■ Clear your voice mail. ■ Press the dial or line button on your telephone. ■ Access an outside line before dialing. ■ Reconfigure the dialing options for your communications package. Most packages have a Wait for Dial Tone Before Dialing option that you can enable or disable if your modem is having trouble detecting a dial tone. You must disable this option to permit blind dialing.
28 CHAPTER 5: USING THE MODEM Attaching this information to faxes is known as fax branding. Refer to your fax communication software documentation for details on how to comply with the fax-branding requirement. AT Commands AT commands are set at the factory (factory settings are called defaults) to perform specific modem functions in preselected ways. They can be used to display call status or send and receive data with communications software such as HyperTerminal.
AT Commands 29 , Causes a delay, determined by S8, before the modem proceeds with the next command or digit. = Same as the ‘,’ modifier except that the delay is doubled. ! Causes the modem to go on-hook for .5 second and then off-hook for .5 second before continuing. @ Causes the modem to wait until it detects 5 seconds of silence before continuing. ; Causes the modem to go to the command mode when the number is dialed.
30 CHAPTER 5: USING THE MODEM I2 The modem performs a ROM checksum, compares the result against a stored value, and returns an OK or ERROR message depending on the success of the comparison. I3 The modem sends its ROM Part Numbers and Revision Levels. I4 The modem sends its ASCII string test. I5 The modem sends its data pump chipset revision. I7 The modem sends platform specific information. N: Handshaking Selects whether a connection will be forced to a specific speed.
AT Commands 31 W: Connection Result Codes Defines the type of (extended) negotiation result codes to return. W0 Negotiation codes not reported. W1 Negotiation codes reported in 3 line format (Hayes format). W2 Negotiation codes reported in 1 line format (Microcom format). W3 Negotiation codes reported in 1 line format (Microcom format). The receive and transmit bit rates will be displayed, Rx/Tx bit rates.
32 CHAPTER 5: USING THE MODEM S Registers AT command settings are stored in S Registers. S-register values can be changed by AT command or by entering the new value of the S Register, preceded by AT. The command ATSn=v changes register n by setting its value to v. For example, to change from manual answer to auto-answer after three rings, follow these steps: 1 Check the S Register table for the register that controls Answering. The functions are listed in alphabetical order.
