3 Basic Modem Operation This chapter covers the basic commands and techniques involved in modem operation. In many cases, this is the only information you will need in order to get your Comet up and running with communication software, and to start making connections with your Comet. Understanding AT Commands The Comet communicates asynchronously with computers using AT commands. AT commands are used to configure and control the Comet.
Bits per second: Data bits: Parity: Stop bits: Flow Control: 115200 8 None 1 Hardware Click “OK” when finished. After you have done this, save your new connection by selecting “Save” from the “File” menu and click “OK.” A new connection icon will be added to your Hyper Terminal folder. You are now ready to start entering AT commands. In the terminal window, type: AT Comet responds OK This confirms that the modem and your computer are communicating correctly.

Quick Tips when issuing AT Commands • The ENTER or RETURN key must be pressed to execute a command. • Multiple AT commands can be combined into one line. For example, AT&D2 and AT&N0 can be combined into one line AT&D3&N0. The Comet processes commands from left to right. The AT command that appears to the right might over-write the command to the left if they are trying to accomplish tasks or set modes that cannot coexist.
AT Command Set/Type Fax and Voice AT+ commands S-Register command S-Register inquiry command Example AT+FCLASS=2 ATS0=1 ATS0? You may browse the lists of available commands for each command set by using the on-line help commands: AT$, AT*$, and AT&$. Modem Result Codes When you execute or try to execute an AT command, your modem sends a result code to let you know whether the command was executed. An OK result code means the AT command you sent was executed.
For example, to have your modem auto-answer an incoming call after two rings, set S-register 0 to 2. Be sure the n value is between 1 and 255. If n is set to 0, your modem will not answer incoming calls. Non-Volatile Memory The Comet has memory set aside for storing user information such as frequently used phone numbers and default command settings. The latter is particularly useful when you use your modem to call a variety of different locations that require different settings.

In most cases, no additional settings will be required.

5 Status Registers & Result Codes In most bit-mapped S-registers, the default bit value is 0. Non-0 default values are followed by an asterisk. Some bits are reserved for factory use and should not be changed. S-Registers "ATSn=x" Command S0 S1 S2 S3 S4 S5 S6 S7 S8 S9 S10 S11 S12 S18 S25 S26 S30 Function & Description Number of rings before Auto Answer. 0 value disables autoanswer. Ring counter. ASCII value of Escape character. ASCII value of Carriage Return character.
S4 - Line Feed Character Sets the character recognized as a line feed. Pertains to asynchronous operation only. The Line Feed control character is output after the Carriage Return control character if verbose result codes are used. S5 - Backspace Character Sets the character recognized as a backspace. Pertains to asynchronous operation only. The modem will not recognize the Backspace character if it is set to a value that is greater than 32 ASCII. This character can be used to edit a command line.
Sets the length of time, in tenths of a second, that the modem waits before hanging up after a loss of carrier. This allows for a temporary carrier loss without causing the local modem to disconnect. S11 - DTMF Tone Duration Sets the duration of tones in DTMF dialing. This value has no effect on pulse dialing.
