ISI5634PCI/4/8 Quick Start Guide
Comm Software Using AT Commands
You must have communications software installed in your computer to
use the Multi-Tech modems on the ISI5634PCI card. If you want to
use communications software that is already installed, you should
reconfigure it for your new modem. Otherwise, install the data and fax
communications software provided with your ISI5634PCI.
1. Turn on your computer and run your communications software.
2. Find the dialog box or menu that allows you to specify your
modem. See different data communications examples below:
• In Windows Terminal, select
Settings and then Modem
Commands
• In HyperTerminal, select File , Properties , and then Phone
Number
3. Select your modem from the software’s modem list. If not listed,
choose a generic modem and modify the settings as necessary.
4. Change the modem initialization string, if necessary. The factory
default configuration works well for most purposes.
• To load the factory default configuration, use
AT&F .
• To load a custom configuration that was saved using the &W
command, use ATZ . Note that the Z command must be in a
command string by itself.
• For a Macintosh, the initialization should include the &D0
command.
• If you don’t want the modem to always answer the phone, add
S0=0 to the string.
Note: To change the modem’s default configuration, type new
commands in the software’s terminal window, adding the &W
command to store them in the modem’s nonvolatile memory.
For instance, to create a default configuration for a Macintosh
computer that turns off autoanswer, type AT&F&D0S0=0&W .
The new configuration loads automatically whenever the modem
is turned on or receives the ATZ command.
