Setting Up the Modem in Windows 95/98
Your modem uses the Plug and Play (PnP) capabilities of you
computer. PnP is a set of specifications that define the ability for
the computer hardware and operating system to automatically
configure all compliant devices that are installed, relieving the
user of the need to determine which addresses and interrupts to
user for each device.
Installing the Driver
The version of Windows 95 you have will determine which set of
dialog boxes is presented to you when installing the modem in
Windows 95. In general, follow these steps:
1. Select My Computer, then Control Panel.
2. Double-click on System.
3. Click on Device Manager.
4. Double-click on Other devices.
5. Click on LT Win Modem.
6. Click on Driver.
7. Click on Update Driver.
8. Select Yes and click on Next.
9. Click on Other Locations….
10. Type <CD-ROM>:\DRIVERS\WIN95\MODEM and click on
OK. (where <CD-ROM> is the drive letter of your CD-ROM
drive, e.g., D).
11. Follow the installation instructions on the screen.
12. Click on Finish.

Installation
4
Installing and Configuring the Software
Install the communication software according to the software
user’s modem of the same COM port and IRQ line used by the
modem.
You may be prompted by the software to configure certain
communication parameters. We suggest the following settings:
Item Suggested Setting
Baud rate 38400 bps
Data bits 8
Parity none
Stop bit 1
Flow control RTS/CTS
Initialization string AT&F
Testing Your Modem
In order to check if the modem is functioning properly, make sure
that the COM Port and IRQ settings of the modem match the
software. Type AT on your terminal screen and press ENTER.
The modem should respond by displaying an OK (or 0). If it does
not, either the modem may not have been installed properly or
the software has not been properly configured.

Installation
5
Setting Up the Modem in Windows NT
Prepare the following to install the modem driver for Windows NT:
 Windows NT 4.0 CD-ROM (includes the PNPISA.SYS file)
 Modem driver diskette
Installing the PNPISA.SYS File
Your modem is a Plug-and-Play modem and requires the
PNPISA.SYS file to work in Windows NT. To install the
PNPISA.SYS file, do the following:
1. Insert the Windows NT 4.0 CD-ROM into the CD-ROM drive.
2. Locate the PNPISA.INF file. This file is generally found in
the \drvlib\i386\ directory of your Windows NT 4.0 CD-
ROM.
3. Right-click on the PNPISA.INF file and select Install to
begin installing the PNPISA.SYS file to your system.
Installing the Driver
Follow these steps:
1. Click on Start, Settings, Control Panel.
2. Double-click on Ports.
3. Remove any redundant port entry by selecting it and
clicking on Delete.
4. Shutdown from Windows NT.
5. Restart your computer.
6. Windows NT detects the modem and prompts you for the
driver (LTMODEM.INF).

Installation

7. Insert the modem driver diskette into the diskette drive and
follow the instructions on the screen install the driver.
Click on Set Configuration Manually to set the COM port
resources. The following resource settings are suggested:
Item Suggested Setting
Modem I/O Address 100-107
COM I/O Address 2F8-2FF
COM IRQ 3
If these settings are in conflict with other devices, you can
select other settings based on the following conditions:
COM Port I/O Address
COM2 2F8-2FF
COM3 3E8-3EF
COM4 2E8-2EF
You can change the the setting by clicking in the Setting
based on: combo box to make it match a setting from the
table above.
Note: Note down the resource settings for future reference.
8. Click on OK to install the driver.
9. Follow the instructions on the screen

Installation

Testing Your Modem
In order to check if the modem is functioning properly, do the
following:
1. Click on Start, Programs, Administrative Tools
(Common), Windows NT Diagnostics.
2. Select the Resource tab, and verify that ltmodem is in the
device list. This means that your modem has been activated
and you have successfully installed the modem driver.
Note: If there is no ltmodem in the list, you need to reinstall the
driver. Before you reinstall the modem driver, delete LT
Win Modem from the Modem item in the Control Panel.
Using Your Modem
The communication software included with your modem provides
a user friendly interface to access the data and fax. The modem
may also perform basic communication functions (such as
dialing) via the AT commands. Please refer to AT Commands for
detailed description. 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.
COM Port and Interrupt Settings
The bundled device driver (optional) can auto configure your
internal modem to appropriate COM port to avoid conflicts with
your computer’s built-in COM ports.
If your modem has to be configured for COM ports 1 or 2, you
must disable the appropriate COM port on your computer. Refer
to your computer manual for specific instructions on how to
disable the COM port.

Installation
8
Common IRQ assignments for COM 1 to COM 4 ports are:
COM Port IRQ
14
23
34
43
Your device driver can be configured to different IRQ: IRQ3,
IRQ10, and IRQ11.

Troubleshooting
9
If you encounter problems while using your modem, please read
this chapter. If you can not resolve your difficulties after reading
this chapter, contact your dealer or vendor for assistance.
Modem does not respond to commands.
1. Make sure the communication software is configured with
the correct COM port and IRQ setting (same COM port and
IRQ setting as the modem). Your communication software
will not be able to send or receive any data if it is not
configured to match the COM and IRQ settings for the
modem.
2. Make sure that your modem is initialized correctly. Your
modem may have been improperly initialized by the software
because you have selected an incorrect modem type. You
may also be prompted to enter an initialization string by the
software. Use AT&F as your initialization string.
Modem does not dial.
1. Make sure the modem is connected to a working phone line.
Replace the modem with a working phone to ensure that the
phone line is working.
Modem dials but does not connect.
1. Make sure the IRQ setting is identical on both the modem
and the software.
2. Make sure the phone line is working properly. A noisy line
will prevent proper modem operation.

Troubleshooting
10
Modem makes a connection but no data appears on your
screen.
1. Make sure all communication parameters (baud rate, data,
stop, and parity bits) are properly configured and are
identical on both sides. Be certain hardware flow control
(RTS/CTS - default) is enabled in both the modem and the
communication software.
2. Press the ENTER key several times. The remote system may
be waiting to receive your data before it begins.
Modem experiences errors while on-line with a remote modem.
1. Make sure Call Waiting is turned off.
2. Make sure RTS/CTS hardware flow control is enabled (do
not use XON/XOFF software flow control when transferring
binary files).
