Protocols define the basic communication link between two modems —...

  • Page 12: Modem Configurations

    You will probably use only one set of communication standards, unless you make international calls. ODEM ONFIGURATIONS Factory Default, Active, and Stored There are three types of modem configurations: factory default, active, and stored. (The stored configuration Feature #120 is available only on certain modem models.) Factory Default: Before your modem left the factory, it was set up to act a certain way.

  • Page 13: Connection Rates

    AT&FØ Load IBM (and all other computers except Macintosh) error correction/data compression configuration. This command sets \N7. If you need to set up your modem to make a direct connection, issue AT \N7. Changing Your Active Configuration Your modem’s AT commands let you change most of the active configuration settings by issuing single commands.

  • Page 14: Error Correction And Data Compression

    tries to “negotiate” error correction and data compression protocols with the other modem. Your modem tries protocols in the following order: first, error correction; then data compression, and finally, neither error correction or data compression. The protocols used are the most powerful protocols that both modems support.

  • Page 15: Connection Types

    V.42 is the ITU error correction protocol, also known as LAPM. V.42bis adds BTLZ data compression to the V.42 protocol. It offers compression of up to 4:1. V.42bis connections require V.42 error correction. Both your modem and the remote modem must support the same data compression/error correction standards if they are to make a data compressing/error correcting connection.

  • Page 17: Using At Commands And Result Codes

    AT C SING OMMANDS AND ESULT ODES This section discusses the following topics: • AT C SSUING OMMANDS • OMMAND TATE AND NLINE TATE • SCAPE • OMMAND YNTAX • OMMAND UFFER • ESULT ODES When you use your telecommunications software to perform a task (such as dialing a phone number), it uses the modem’s AT commands to perform the task.

  • Page 18: Command State And Online State

    AT [CR] ([CR] represents a carriage return.) If the modem responds with OK, it means that the modem has received and understood the command. You are in terminal mode and ready to issue AT commands. If you are not in terminal mode, refer to your software manual to determine how to get there.

  • Page 19: Command Line Syntax

    The plus signs in the escape code can be changed to another ASCII character by changing the value in Register S2. S Registers contains more information on setting S Registers. OMMAND YNTAX The prefix AT (“ATtention”) must start each command line except A/. The modem examines the AT code to determine your computer’s serial port rate, parity, word length, and number of stop bits.

  • Page 20: Command Line Buffer

    OMMAND UFFER The modem places each command issued into a command buffer that holds up to 160 characters. The modem does not place the AT, carriage return, or line feed characters into the buffer, so the buffer’s 160 spaces only hold actual command characters (and any spaces between them). If a command line contains more than 160 characters, the modem stops showing what you type on the screen and it ignores further commands.

  • Page 21: Dialing

    IALING This section discusses the following topics: • SING THE OMMAND • TORING A ELEPHONE UMBER • IALING A TORED ELEPHONE UMBER • UTOMATIC ULSE IALING • ISABLING AITING Most of the time you will use your fax or data software to dial numbers, and you will not need the information in this section.

Command Command Definition Modifier - ( ) To aid readability, spaces, hyphens and parentheses can be used in the command line without affecting its function (any numeric digit) Causes the indicated digit to be dialed. (tone dial only) Causes the indicated symbol to be dialed.

  • Page 23: Storing A Telephone Number

    If your modem does not receive a valid carrier from the remote modem within 50 seconds (the default value of register S7), your modem hangs up and sends the NO CARRIER Result Code (or 3 if in numeric mode). If the modem does receive a valid carrier within the time allowed, it sends a CONNECT XXXX message indicating a connection has been made.

  • Page 24: Disabling Call Waiting

    Note that this mode can cause problems with PBX systems — for example, systems where a 9 is dialed to get a dial tone outside a company’s in-house phone system. Such systems deliver a second dial tone after receiving the first digit. With PBX and similar systems, include the T or P command in the dial string.

  • Page 25: Answering

    NSWERING This section discusses the following topics: • NSWERING ALLS • ALLER Your modem can answer telephone calls and (with help from your data or fax software) manage those calls appropriately. Under certain conditions, the modem can also tell you who is calling before the call is answered.

  • Page 26: Caller Id

    If you plan to use your modem to run a Bulletin Board System (BBS), the BBS software should automatically configure it for auto answer operation. If you think that you need to change it, refer to your BBS software manual or contact the BBS software publisher for details on how your modem should be set.

  • Page 27: High Speed Communication

    PEED OMMUNICATION This section addresses some of the issues that you should be aware of as you work with modems that communicate at speeds of 33,600 bps and above. This section discusses the following topics: • 56K M ODEM ECHNOLOGY •...

  • Page 28: Bps Connections

    Recently, phone companies have begun to deliver a digital line (in the form of a T-1, equivalent to 48 voice lines) from their Central Office to the ISP. By upgrading ISP dial-up modems with a digital connection to a T-1 line, one less analog to digital conversion is made between the ISP and their Central office.

  • Page 29: Asymmetric Data Rates

    Problem issues such as serial port speed, slow downloads, multitasking, and line noise are discussed in Solving Problems. SYMMETRIC ATES A connection where the carrier rates can be different in each direction is referred to as “Asymmetric.” Many K56flex and V.34 modems have the ability to use the “best match” carrier rate in each direction.
  • Page 30 For example, to set your modem to operate as a V.32bis modem, enter: AT+MS = V32b,1,9600,14400[CR] You can leave a parameter at its current value by leaving that parameter’s place blank and entering a comma to separate the parameters or by entering a carriage return ([CR]) if it is the last parameter.
  • Page 31 <mod> <mod> Protocol Possible Numeric Verbose Rates (bps) K56flex 56000, 54000, 52000, 50000, 48000, 46000, 44000, 42000, 40000, 38000, 36000, 34000, 32000 B103 Bell 103 B212 Bell 212 1200 1 See optional <automode>, <minimum rate>, and <maximum rate> parameters. 2 For V.23, originating modes transmit at 75 bps and receive at 1200 bps; answering modes transmit at 1200 bps and receive at 75 bps.

  • Page 32: Rate Renegotiation

    The <minimum rate> Parameter The <minimum rate> is an optional number that specifies the lowest rate at which the modem may establish a connection. The default is 300 bps. The <maximum rate> Parameter The <maximum rate> is an optional number that specifies the highest rate at which the modem may establish a connection.
