Chapter 3 – Software Configuration
Configuring Communications Software
Configure your communications software to work with your modem, your computer, and the remote system it
calls. Most communications programs provide a default initialization string and default settings for other
parameters.
To configure you communications software to work with the MT5600BR-V92 modem:
● Set the modem initialization string.
This is a command sequence that the software uses to configure the modem when loading communications
software or beginning a session.
● Always begin the initialization string with AT.
● Follow the AT with the modem reset command, &F, to ensure that you are starting with a known state.
● Additional commands depend on the modem’s capabilities and what you want it to do.
● Newer communications programs provide initialization strings when you select your model from a list. If
the MT5600BR-V92 is not listed, select MultiModemII.
Note: Modem capabilities and command implementations vary from modem to modem. If you use an
initialization string intended for another modem, particularly one from another manufacturer, you
might not have access to some modem features.
PC Initialization Strings
We recommend the following initialization string for a MT5600BR-V92 connected to a PC-compatible computer:
AT &F X4 S0=0 ^M
This string:
● Resets the MT5600BR-V92 to the factory default settings
● Selects extended result codes with NO DIAL TONE and BUSY, and turns off auto-answer.
Notes: If you send commands through communications software, you must end every string with ^M. This is
the ASCII code for the Return key on most keyboards, the default code for carriage return in the
MT5600BR-V92, and most communications programs.
If you send commands to the modem in terminal mode, you must press Return (<CR>) to end every
string.
In the MT5600BR-V92, the carriage return character is defined in S-register S3. If you change it, also
change the carriage return character code used in your communications software.
