Changing Default Parameters

The default values for the other parameters in modem configuration menus rarely need changing. They typically include the dialing prefix (ATDT for touch-tone service and ATDP for rotary service), the dialing suffix (^M), the hang-up string (+++ATH0^M), and response messages (RING, NO CARRIER, BUSY, etc.). Communications software with a host mode might also include an auto-answer string (AT S0=1^M).

Configuring Software for Your Computer

You must configure your communications software to match your computer’s configuration. If the MT2834ZPX is connected to the COM2 communications port, you must tell the software you are using COM2. Another important parameter is the serial port baud rate. This is the speed at which your modem communicates with your computer, not the speed at which your modem communicates with another modem. When V.42bis data compression is enabled, you must have a serial port baud rate four times the transmission speed of the modem to optimize making data compression effective.
