2.3 Testing Your Modem

To confirm that the modem is working properly after installation, run

a modem communication program and set the software for the correct

modem COM port (internal modem factory defaults to COM4). At the

software's terminal mode prompt, type AT followed by the ENTER key. The

modem should respond by displaying an OK (or 0). The OK (or 0)

response indicates that the modem is working properly. If the modem does

not return the proper response, refer to

Section 2.2.1

for information on

COM Ports and IRQ setting for

Section 5

for troubleshooting information.

2.4 Using Your Modem

Common modem functions (i.e. dialing, file transfer, faxing) are performed

by using communication software in conjunction with the modem.

The

communication software included with your modem provides a user

friendly interface for all common modem functions and should be

sufficient for all of your communication needs

. The modem may also

perform basic communication functions (such as dialing) via the AT

commands. A list and description of all AT commands appears in

Section

. Since the communication software is designed to shield the user from

the difficult and cumbersome AT commands, we strongly suggest that all

modem operations be performed via the software.

Section Three - Software Installation

3.1 Using The Internal Modem With Microsoft Windows 3.1

It is very important that you

configure Windows 3.1 to recognize the

internal modem after installation or when the modem's COM/IRQ

settings have been changed.

Your internal modem has been designed

to provide flexible hardware configurations to satisfy different systems

requirements. For example you may change the modem's operating

setting from COM4/IRQ3 (default) to COM3/IRQ5 to avoid hardware

conflicts with other serial devices in your system.

After installation or

setting changes, make sure Windows is properly configured before

running your Windows communicaion software.
