AT Commands/S-Registers Chapter 4--Introduction One of the means by which you can communicate with and configure your MTA128ST is to use AT commands. AT commands are so-called because, with only a few exceptions, each command string must begin with the characters AT. Using AT commands, you can read and set parameters, and perform actions such as dialing. 4.1.
AT Commands/S-Registers value in register S2. You can send the break signal in the out-of-band escape sequence only from software, not by pressing SHIFT+BREAK on your keyboard. When it detects the escape sequence, the MTA128ST enters online command mode, in which it responds to commands while maintaining the connection with the remote device. The MTA128STs command buffer can store 80 characters, including spaces and other characters used in telephone numbers.

(Use the Q command to enable or disable the display of result codes.) V0 V1 Command: Function: Values: Default: Enable terse result codes. Enable verbose result codes.
AT Commands/S-Registers Note that whereas the &F0 reset command always restores the factory default profile, the Z reset command restores either the factory default or the stored profile, depending on how the &W command is set. Command: Function: Values: Default: &Cn DCD Control n = 0, 1, or 2 &C1 (DCD normal) Description: The &C command controls the behavior of the DCD (Data Carrier Detect) signal (pin 8 on the RS232E/V.24 interface).
AT Commands/S-Registers &D3 When DTR goes low, the MTA128ST resets the data port and disables autoanswer. If DTR goes low when the MTA128ST is online, the MTA128ST hangs up, resets the active configuration to the stored configuration, and disables autoanswer. *: If the user wishes to accept calls while DTR is low, the MTA128ST must be configured to ignore DTR. This is accomplished by entering AT&D0. With this configuration, the MTA128ST is able to accept calls while DTR is low.
AT Commands/S-Registers &E7 &E12 &E13 When XON/XOFF pacing is active, the MTA128ST responds to the XON/XOFF characters and passes them through the communications link to the remote device, thereby pacing the remote terminal adapter as well. Disables pacing Enables pacing. Command: #Xn Function: Send Single/Multiple Xoff Characters Values: n = 0 or 1 Default: #X0 Description: The #X command allows the MTA128ST to send either a single or multiple Xoff characters to exert flow control to the terminal.

AT Commands/S-Registers Command: Function: Values: Default: %En Escape Sequence Options n = 05 %E1 and %E4 Description: By default, the modem responds only to the +++ escape method. However, you can use the %E command to set the modem to respond only to the method, to respond to either the +++ or the method, or to ignore both methods and not escape. %E0 %E1 %E2 %E3 %E4 %E5 %E1 %E5 %E3 %E5 Command: Function: Values: Default: Modem wont escape. +++ escape method. escape method.
AT Commands/S-Registers Command: Function: Values: Default: @P4=n Data Bits n = 7 or 8 @P4=8 (8 data bits) Description: Use this command only to set the number of data bits the MTA128ST uses when it is turned on. Once the MTA128ST receives an AT command from the computer, it automatically adjusts to the number of data bits the computer is using.
AT Commands/S-Registers Command: Function: Values: Default: D Dial none none Description: The D command causes the MTA128ST to dial a telephone number (e.g., ATD785-3500 ). Command: Function: Values: Default: Hn Hang Up n = 0 or 1 H0 Description: The H command forces the MTA128ST to go off-hook (to take control of the telephone line) or to go on-hook (hang up). Since the MTA128ST goes off-hook automatically when it dials, the H command is normally used only to hang up.
AT Commands/S-Registers Command: Function: Values: Default: O Return Online none none Description: The O command returns the MTA128ST to online mode from the online command mode. When the MTA128ST makes a data connection, it enters online data mode. The MTA128ST typically remains in this mode until it receives an escape sequence or until the call is ended. When it detects an escape sequence, the MTA128ST enters online command mode, in which it can accept AT commands while retaining the online connection.
AT Commands/S-Registers 4.2 S-Registers S-Registers are sections of memory in which values are stored that affect how the MTA128ST operates. S-Registers are so-called because each has a name that begins with the character S. Use the S command to assign a value to or to read the current value of an S-register. To assign a value to an S-register, use the command Sr=n, in which r is the register number, and n is the value you want to assign to the register, e.g., S7=45.
AT Commands/S-Registers S-Register: Function: Unit: Range: Default: S0 Number of Rings Until Answer 1 ring 0255 1 Description: S0 sets the number of rings the MTA128ST waits for before it answers and begins its connect sequence. S0=0 turns off the ability to automatically answer a call. S0=1 causes the MTA128ST to automatically answer after 1 ring. Note that if the S0 value is set too high, the calling device may time out before the MTA128ST answers the call.
AT Commands/S-Registers S-Register: Function: Unit: Range: Default: S3 Carriage Return Character Decimal ASCII code 0127 13 (^M) Description: S3 specifies the character used by the MTA128ST to indicate the end of a command line. S-Register: Function: Unit: Range: Default: S4 Line Feed Character Decimal ASCII code 0127 10 (^J) Description: S4 specifies the character used by the MTA128ST to indicate the end of a status message.
AT Commands/S-Registers S-Register: Function: Unit: Range: Default: S10 DCD Drop Time 50 ms 0254, 255 20 Description: S10 sets the time after a carrier signal is lost before the MTA128ST disconnects. (The &C2 command must be in effect.) The default setting is one second. Maximum delay is 25.4 seconds (S10=254). Set S10 to 255 to cause the MTA128ST not to disconnect with loss of carrier.
AT Commands/S-Registers S-Register: Function: Unit: Range: Default: S50 Caller Line ID CLI Decimal ASCII code 0 or 1 1(enabled) Description: S50 sets whether the mechanism for identifying the two endpoints of a connection is enabled or disabled. Since RING messages only appear for ISDN data calls, the CLI feature does not define a means of conveying Calling Party information to the terminal for ISDN voice calls.
AT Commands/S-Registers S-Register: Function: Unit: Range: Default: S52 Auto-Protocol Detection Decimal ASCII code 0 or 1 1 Description: S52 sets whether the mechanism for identifying V.110, V.120, X.75, MLPPP, or SoftBond operation is enabled or disabled. This is applicable for an ISDN data call; and once determined by the MTA128ST the protocol used by means of the information conveyed by the SETUP message, then the indicated protocol is activated.

AT Commands/S-Registers 4.4 Using AT Commands to Operate the MTA128ST You can configure and operate the MTA128ST entirely with AT commands, if you like. Remember, you can issue AT commands only from a terminal or from a computer running a communications program in terminal mode. This section decribes how to use AT commands for basic operations, such as calling, answering a call, and hanging up. 4.4.
AT Commands/S-Registers Dialing To dial a number using AT commands, you must first start a data communications program. In the programs terminal mode, type ATDxxxxxxx, where xxxxxxx is the telephone number you want to dial, and is the carriage return character that is sent when you press the ENTER key, e.g, ATD7853500. The dial string can contain up to 80 characters. To place an ML-PPP call, use an ampersand character (&) to join two telephone numbers, e.g., ATD7853500&7853502.
AT Commands/S-Registers Canceling a Call To cancel a call before the MTA128ST makes a connection, press any key. Storing a Telephone Number To store a telephone number, type &Zn=x in terminal mode, where n is the number of the memory register in which the number is to be stored, and x is the dial command string that you want to store. For example, type AT&Z9=612-785-3500 to store the number 612-785-3500 in memory register 9.
AT Commands/S-Registers MTA128ST answer on the fourth ring). You can also use either of the configuration utilities to the turn autoanswer on and set the number of rings. 2. Make sure that the MTA128ST is offline. The MTA128ST will answer the call after the number of rings specified by S0. To disable autoanswer, use a configuration utility or the command S0=0. *: If the user wishes to accept calls while DTR is low, the MTA128ST must be configured to ignore DTR. This is accomplished by entering AT&D0.
Troubleshooting Chapter 5--Introduction This chapter describes some basic problems you may run into with your MTA128ST and how to solve them. 5.2 Troubleshooting Your MTA128ST was thoroughly tested at the factory before it was shipped. If you are unable to make a successful connection, or if you experience data loss during your connection, it is possible that the MTA128ST is defective. However, it is more likely that the source of your problem lies elsewhere.
Troubleshooting 4 If the power supply is plugged into a power strip, make sure the power strip is plugged in and its power switch is on. 4 Make sure the power supply module is firmly connected to the MTA128ST and to the wall outlet or power strip. 4 If the power strip is on and the MTA128ST is switched on, try moving the MTA128ST power supply to another outlet on the power strip. 4 Test that the outlet is live by plugging a lamp into it. 4 The MTA128ST or power supply may be defective.
Troubleshooting can access the MTA128ST at a time. If MultiExpress Terminal reports that it cannot make a connection, yet the MTA128STs TR indicator is on, click on the Window menu to see if more than one terminal is open. The MTA128STs TR indicator shows that the software has made a connection with the MTA128ST through the COM port. 4 Your communications software settings may not match the physical port the MTA128ST is connected to.
Troubleshooting Properties sheet, click on the Resources tab to see the ports Input/Output range and Interrupt Request. If another device is using the same address range or IRQ, it will appear in the Conflicting Device List. Uncheck Use Automatic Settings to change the ports settings so they do not conflict with the other device, or select the port the conflicting device is on and change it instead.
Troubleshooting pairs. The cable must have at least the middle four pins (pins 2, 3, 4, and 5) connected. A reversed pair on the U (phone company) side is not important, but a reversed pair on the S/T (your) side can create problems if you have more than one device, since multiple devices attached to the S/T interface must all have the same polarity. 4 If the MTA128ST reports BUSY, the other number may be busy, in which case you should try again later.
Troubleshooting * In Windows 95, if the Use Country Code and Area Code box is checked in the Properties window for dial-up connection, the bundling modifier (i.e., &, + or !) is removed from the dialing string when the user attempts to make a connection. The solution is to not check the Use Country Code and Area Code box, or to simply add the bundling dial modifier to the phone number at the time of connection.
Troubleshooting 4 Check the serial port baud rate in your communications software, and make sure it is set as high as your UART allows. Data Is Being Lost 4 Your UART may not be reliable at serial port speeds over 9600 bps or 19,200 bps. Reset your serial port speed to a lower rate, or replace your serial port with a faster one. 4 Check the serial port baud rate in your communications software, and make sure it is set as high as your UART allows.
