13 Chapter 2 - Installation and Configuration Operating Your MT2834ZPX You control your MT2834ZPX by issuing AT commands and setting S- Registers. Right now your MT2834ZPX is set up for the most typical user application, that is, as a traditional modem set to make a dial-up call to a remote installation where the call is answered automatically; the[...]

14 MT2834ZPX Owner's Manual Simple Operations You can dial a number by using the ATD command and the phone number of the modem with which you wish to connect, e.g., ATD6127853500 . Your modem will dial the number; a “scrambling” noise is heard as the modem negotiates the kind of connection it can make, and once the modems have settled on a[...]

15 Chapter 3 - Software Configuration Chapter 3 - Software Configuration Introduction Communications software must be configured to work with your modem, your computer, and the remote system it is calling. Fortunately, most communications programs make the process easy by providing a default initialization string for your modem as well as defaults [...]

16 MT2834ZPX Owner's Manual PC Initialization Strings We recommend the following initialization string for a MT2834ZPX connected to a PC-compatible computer: AT &F X4 S0= 2 ^M This string resets the MT2834ZPX to the factory default settings, selects extended result codes with NO DIAL TONE and BUSY, and turns on auto-answer to answer on the[...]

17 Chapter 3 - Software Configuration Changing Default Parameters The default values for the other parameters in modem configuration menus rarely need changing.

19 Chapter 3 - Software Configuration File Transfer Protocols When you upload or download files with your modem, the host computer will ask which file transfer protocol you want to use. Most communications programs allow you to choose a default protocol. Your software’s documentation should list the ones it can use (not all communications program[...]

20 MT2834ZPX Owner's Manual As a general rule, you should try to transmit files in already- compressed form rather than relying on V.42bis hardware compression. Because software compression is more efficient than hardware compression, you will have a higher throughput with the former. Of course, this efficiency does not include the time spent [...]

21 Chapter 3 - Software Configuration To enable the buffer, use Notepad to open the SYSTEM.INI file in your Windows directory, and add the following line to the [386Enh] section: COMnFIFO=1 where n is the number of the COM port the 16550 is installed on. For example, if the 16550 is installed on COM2, the line should be: COM2FIFO=1 After you save S[...]

22 MT2834ZPX Owner's Manual Chapter 4 - AT Commands, S-Registers and Result Codes Dialing/On-Line/Answering There are several basic steps for “originating” and “answering” in data communication mode: 1.
