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.
The next window sets the COM port settings. The settings used for the Comet should be as follows: 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.
Pausing During Dialing: ATDT 9,,555 1212 Dialing Without Waiting for Dial Tone: ATX0D, 555 1212 Originating a call using an Answer Tone: ATDT 555 1212,,,,,,R Redialing the Last Number Called: ATDL Waiting for Five Seconds of Silence: ATDT 800 555 1212 @ 123456,1 714 555 1212 Transferring a Call (using flash hook): ATDT! 2468 Auto-Answer and Hook Controls Enabling Auto-Answer: ATS0=n Note: In this example, n is a number from 1 to 255 that corresponds to the number of rings after which your mode
• Multiple AT commands can be combined into one line. For example, AT&D2 and AT&K0 can be combined into one line AT&D2&K0. 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. • If you see duplicated characters for each one you type, your Comet and software both have their “echo” feature turned.
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. If you receive an ERROR code, it means the command was invalid. The Comet also provides result codes that show: • Whether or not a Dial Tone was detected when the modem originated a call. • If a busy signal was detected when the modem originated a call.
The ‘s’ is a number from 0 to 3 that represents the location in memory that the phone number is to be stored, and the ‘n’ is the phone number itself. Example: To store the number ‘1-714-555-1212’ in memory location ‘2’, type: AT&Z2=17145551212 You can store up to 4 telephone numbers. Dialing Stored Phone Numbers The AT command syntax used to dial a store number is ATDS=n. The ‘n’ is the memory location of the stored number you want to dial.
