PORTABLE USB MODEM 4. AT Commands, S-Registers, and Result Codes 4.1 AT Commands AT commands are used to control the operation of your modem. They are so called because each command must be preceded by the characters AT to get the ATtention of the modem. AT commands can be issued only when the modem is in command mode or online command mode. The modem is in command mode when it is not connected to another modem. The modem is in data mode when it is connected to another modem and ready to exchange data.
CHAPTER 4: AT Commands, S-Registers, and Result Codes You can issue several commands in one line, in what is called a command string. The command string begins with AT and ends when you press ENTER. Spaces to separate the commands are optional; they are ignored by the command interpreter. The most familiar command string is the initialization string, which is used to configure the modem when it is turned on or reset, or when your communications software calls another modem.

CHAPTER 5: Remote Configuration 5. Remote Configuration 5.1 Introduction Remote configuration is a network management tool that allows you to configure modems anywhere in your network from one location. With password-protected remote configuration, you can issue AT commands to a remote Portable USB Modem for maintenance or troubleshooting as if you were on-site. 5.2 Basic Procedure The following steps are valid regardless of whether the connection is established by the local or the remote modem. 1.
PORTABLE USB MODEM 5.3.1 CHANGING THE SETUP PASSWORD 1. Open a data communications program such as HyperTerminal. 2. In the terminal window, type AT#Sblackbox (or AT#Syyyyyy if you have replaced the blackbox password with yyyyyy) and press ENTER. The modem responds with OK if the setup password is correct and ERROR if it is wrong. 3. To change the password, type AT#S=yyyyyy, where yyyyyy stands for the password, and press ENTER.
CHAPTER 6: Troubleshooting 6. Troubleshooting Your modem 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 or garbled characters during your connection, the modem might be defective. However, it is more likely that the source of your problem lies elsewhere. The following symptoms are typical of problems you might encounter: • None of the LEDs light when the modem is on. • The modem does not respond to commands.
PORTABLE USB MODEM • Try resetting your modem by unplugging the USB cable from the modem, and then plugging it back in. • Try rebooting the computer. • The modem might be defective. If you have another Portable USB Modem, try swapping modems. If the problem goes away, the first modem is possibly defective. Call Tech Support for assistance. 6.3 The Modem Dials But Cannot Connect There can be several reasons that the modem fails to make a connection.
CHAPTER 6: Troubleshooting • If the modem reports BUSY, the other number might be busy, in which case you should try again later, or it might indicate that you have failed to add a 9, prefix to the phone number if you must dial 9 for an outside line. If you must dial 9 to get an outside line, the easiest way to dial it automatically is to include it in the modem’s dial prefix, for example, ATDT9,. Note the comma, which inserts a pause before the number is dialed.
PORTABLE USB MODEM • If you have extension phones on the same line as your modem, you or someone else can interrupt the connection by picking up another phone. If this is a frequent problem, disconnect the extension phones before using the modem, or install another phone line especially for the modem. • Check for loose connections between the modem and the computer and the telephone jack.
CHAPTER 6: Troubleshooting 6.8 Calling Black Box If you determine that your Portable USB Modem is malfunctioning, do not attempt to alter or repair the unit. It contains no user-serviceable parts. Contact Black Box at 724-746-5500. Before you do, make a record of the history of the problem. We will be able to provide more efficient and accurate assistance if you have a complete description, including: • the nature and duration of the problem. • when the problem occurs.
PORTABLE USB MODEM Appendix A. V.90 Support A.1 Introduction V.90 is the ITU designation for what had been formerly called V.pcm. The ITU recommendation V.90 was determined at a meeting in Geneva ending February 6, 1998. V.90 will replace K56flex and other proprietary solutions for PCM connections. Dual-mode client modem code will be important until all central-site digital modems are upgraded to V.90 and all interoperability problems have been resolved.
APPENDIX B: Loopback Tests Appendix B. Loopback Tests B.1 Introduction Each time you turn on your modem, it performs an automatic self-test to ensure proper operation. Your modem also has three diagnostic tests: local analog loopback, remote digital loopback, and local digital loopback. These ITU-T V.54 loopback tests isolate telephone circuit and transmission problems.
PORTABLE USB MODEM B.2 Local Analog Loopback Test (V.54 Loop 3) In this test, data from your computer or terminal is sent to your modem’s transmitter, converted into analog form, looped back to the modem’s receiver, converted into digital form, and then sent to your monitor for verification. No connection to the phone line is required. AT&T1 CONNECT UUUUUUUUU UUU Digital Computer or Terminal Analog Portable USB Modem Local MultiModem Figure B-1. Local analog loopback test.

APPENDIX B: Loopback Tests 6. Your modem passes this test if the data received on your monitor are the same as the data entered from your keyboard. If different data appear on your monitor, your modem is probably causing the problem, though it could also be your computer. If your modem passes this test, but you are receiving errors while on line, the remote modem or the phone line could be at fault. B.3 Remote Digital Loopback Test (V.
PORTABLE USB MODEM 5. Type AT&T6 and press ENTER. The local modem responds to this command by transmitting an unscrambled marking signal, which causes the remote modem to place itself in digital loopback mode. Then the local modem exits online command mode and enters data mode. 6. Enter data from your keyboard. For this test, typing multiple uppercase U characters is a good way to send an alternating test pattern of binary ones and zeroes.
APPENDIX B: Loopback Tests TEST PROCEDURE 1. Open your communications software and go into terminal mode. Type AT and press ENTER; you should get an OK message. Type AT\N and press ENTER to disable error correction. 2. Dial the remote modem and establish your online connection. 3. Type the escape sequence +++AT and press ENTER to bring your modem into online command mode. 4. Type AT&T3 and press ENTER.

PORTABLE USB MODEM Appendix D. Upgrading the Modem D.1 Introduction Your modem is controlled by semi-permanent software, called firmware, which is stored in flash memory. Firmware is nonvolatile; that is, it remains stored in memory when the modem is turned off. However, it can be changed by either the manufacturer or the user as bugs are fixed or new features are added.
APPENDIX D: Upgrading the Modem IDENTIFY THE MODEM FIRMWARE You must know the model number and firmware version of your modem to know whether or not you should upgrade it. 1. Run your favorite terminal program. You can use HyperTerminal for Windows 98, Me, 2000 or Windows NT. 2. In the program’s terminal window, type AT&F. Even if you cannot see the AT&F command on your screen, be sure to type it completely, and then press Enter. If the modem does not respond with OK, repeat the AT&F command. 3.
