Chapter 4 - AT Commands, S-Registers, and Result Codes Using AT Commands to Operate the MTA128ST-USB You can configure and operate the MTA128ST-USB entirely with AT commands if you like. But remember, you can issue AT commands only from a terminal or from a computer running a communications program in terminal mode. This section describes how to use AT commands for basic operations, such as calling, answering a call, and hanging up. Modes of Operation The MTA128ST-USB has three modes of operation.
MultiModemISDN User Guide Note: In Windows 2000 and Windows 98/95, 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.
Chapter 4 - AT Commands, S-Registers, and Result Codes this, enter AT&D0. With this configuration, the TA can accept calls while DTR is low. If this configuration setting is not made, the TA rejects incoming calls until DTR is high while calls comes in. Hanging Up To hang up a call, escape to online command mode (+++AT), then enter the H command (ATH). The escape sequence and hang up command can be combined into one command string: +++ATH.
Chapter 5 - Troubleshooting
Chapter 5 - Troubleshooting Introduction This chapter describes basic problems you may run into with your MTA128ST-USB and how to solve them. Your MTA128ST-USB 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, check the following possibilities before calling Technical Support (see Chapter 6). • None of the LEDs light when the MTA128ST-USB is on.
MultiModemISDN User Guide • Make sure you are in terminal mode in your data communications program. Then type AT and press ENTER. If you get an OK response, your connections are good and the problem may be in your phonebook entry or session settings. • If you don’t get an OK, the problem may still be in the communications software. Make sure you have done whatever is necessary in your software to make a port connection. Not all communications programs connect automatically to the COM port.
Chapter 5 - Troubleshooting • A faulty communications device, computer, or software at the other end. • Incompatibility between communications devices. • An improperly configured MTA128ST-USB. Narrow the list of possibilities by using extended result codes. To enable them, enter ATV1X2 and press ENTER while in terminal mode or include V1X2 in the MTA128ST-USB’s initialization string (V1X2 is enabled by default). When you dial again, the MTA128ST-USB reports the call’s progress.
MultiModemISDN User Guide The MTA128ST-USB disconnects while online • Check for loose connections between the MTA128ST-USB and the computer, the ISDN jack, and AC power. • The problem may have originated at the other end of the line. Try again. • If you were online with a BBS or online service, it may have hung up on you because of lack of activity on your part or because you exceeded your time limit for the day. Try again. The MTA128ST-USB cannot connect when answering • Autoanswer may be disabled.
Chapter 5 - Troubleshooting sending terminal adapter, then the packet size can be greater than 1024, and Zmodem transfers the data without bad packet errors. Note: The MTA128ST-USB is manufactured in two builds. To determine the build of your terminal adapter (TA), issue the ATI2 command in a terminal window. If the TA responds to the command with MTA128ST-USB, then it supports V.110. If your TA resonds to the ATI2 command with MTA128ST-USB-RC, V.110 support is not available.
