----------------------------------------------------------------
2. Installing Your Modem on an HP Omnibook 800CS, an NEC 6030,
or an IBM 760 XL Computer
Uninstall the old modem by following the instructions in
section 1b) above.
DO NOT RUN SETUP. Simply insert the modem into the PC Card
slot and allow Windows to autodetect it. When you are
prompted, select "Disk Provided by Manufacturer" and insert
the Modem Installation Diskette. After the computer has
rebooted and you hear the tones indicating the modem is
inserted, run a:\setup from the Modem Installation to copy
necessary files to your computer.
---------------------------------------------------------------
3. Installing Your Modem in Windows 3.x
Card and Socket Services must be loaded on your computer before
you install the XJ2560 or CC2560 modem.
If you have previously used a point enabler to install a modem
in 3.x, you must comment out the point enabler lines in your
CONFIG.SYS file.
Follow the instructions in section 1 to uninstall and then
install your modem.
---------------------------------------------------------------
4. If You are Using a Texas Instruments Notebook with a
Phoenix Card Manager
At ship time, there were known issues with functionality in a
Texas Instruments notebook using a Phoenix card manager such
as TI Extensa and TI TravelMate. 3Com is working together
with the laptop manufacturer to resolve these issues. Check
http://www.mhz.com/client/mcd/support for 3Com Technical
Bulletin #3193. You might also call the support phone number
for your notebook or access http://www.acer.com.
---------------------------------------------------------------
5. If You are Using an IBM 760C or an IBM 365XD Computer
If your computer disables the COM port when it goes into
sleep or suspend mode, the modem will not respond when resume
is used. The modem will respond if, with the computer running,
you remove and reinsert the modem.
----------------------------------------------------------------
6. If You Receive the Message "Com Port is Unavailable" During
Setup
If you are installing your modem on a laptop that uses a
Databook controller and you insert the modem before you boot
the computer, the message "Com Port is Unavailable" will
appear. If this happens, remove the modem and reboot the
computer. Once the laptop is running under Windows, insert
the modem.
Some laptops that have Databook controllers are:
Ambra Subnote
AMS Soundpro
AMS Travelpro
Austin 486
Canon Innovabook 10
Canon Innovabook 100
Epson Action Note 4000
Midwest Micro Elite
Sharp 3010
Sharp 8650
Sharp 8700
Sharp 8900
Twinhead Subnote
Unisys
--------------------------------------------------------------
7. Using the Diagnostic Software
DIAGNOSE.EXE allows you to easily collect information about
your computer and any inserted PC Cards. The information is
then used to verify that your system is running correctly, or
to fix any problems. To run the Diagnostic Software you need
to use your original Installation Disk. This disk is different
from the upgrade disk that you created earlier.
To use DIAGNOSE, follow these steps:
1. With Windows running, insert the Installation Disk into
the drive on your computer
2. Select "Start" (Windows 95) or "File" (Windows 3.x)
3. Select "Run"
4. Type A:\DIAGNOSE and click OK
Select the tests you want to perform from the menus at the top
of the screen.
---------------------------------------------------------------
8. Disabling IBM Internal Modems
If you are using an IBM Thinkpad 755CSE or other IBM computer
that has an internal modem, you must disable it in order to
use your PC Card. To do this, follow these steps:
1. Load Windows
2. Click Start
3. Click Programs
4. Open the IBM Thinkpad Setup Group
5. Open the DSP Icon
6. Remove the check from the Telephony Function
7. Save
8. Restart the computer
---------------------------------------------------------------
9. If You are Using an NEC Versa M/100 Computer
No audible tones will be produced when you insert or remove
your modem from an NEC Versa M/100.
---------------------------------------------------------------
10. If You are Using Quicken Version 6
The default maximum baud rate of a modem in Quicken 6 is
19,200bps. Follow the instructions in the Quicken 6 manual to
increase this baud rate for your Megahertz modem.
---------------------------------------------------------------
11. If You are Using Microsoft Exchange
If your system locks up whenever you attempt to use the
following features of Windows Messaging (formerly Microsoft
Exchange):
- MS Fax
- E-Mail
- Dial-up Networking
- Dial-up Internet Explorer
download "Microsoft Exchange Update For Windows 95", file
EXUPDUSA.EXE, from the Microsoft Web Site at
http://www.microsoft.com/windows/software/exupd.htm
---------------------------------------------------------------
12. If You are Connecting to a Comsphere 3820+ Modem
When you're connecting to a Comsphere 3820+ modem at speeds of
4800bps or lower, you must disable the V.8 protocol in your
modem. To do this, change S-Register 32 from the
default 2 to 0.
---------------------------------------------------------------
13. Removing the Modem From Its Slot in Windows 3.x
When running under Windows 3.x, removing the modem while it is
connected will cause your computer to lock up.
---------------------------------------------------------------
14. Adjusting the Modem's Speaker Volume
The speaker volume cannot be adjusted. ATL0, 1, 2, and 3 all
produce the same sound level.
---------------------------------------------------------------
15. Uninstalling the Modem
When you have run uninstal.exe, the US_Robo... icon will not
disappear from the control panel until you refresh your screen
by pressing F5.
See section 1c) above for uninstall procedure.
---------------------------------------------------------------
16. Loopback Tests
The following loopback AT commands are not supported: Local
Analog Loopback (AT&T8), Remote Analog Loopback (AT&T1, Local
Digital Loopback (AT&T6), and Remote Digital Loopback (AT&T3).
The Remote Digital Loopback (AT&T7) doesn't work correctly on
this modem.
---------------------------------------------------------------
17. If You Encounter Problems When Faxing
If you run into problems while you are faxing, try changing the
fax class you are using to 2.0 if you are using Class 1, and to
Class 1 if you are using 2.0.
If you are using RapidComm communications software, also change
the initialization strings to extend the dial tone wait time.
To do this, follow these steps:
1. Double click on Rapidcomm to bring up the program
2. Click Setup
3. Click Modem
4. Click on the end of the Initialization line, and add
"S6=10&W" at the end of the line.
5. Click OK
---------------------------------------------------------------
18. Using Error Correction Mode when Faxing
Error correction mode (ECM) is not supported by this modem.
If your communications software supports ECM, set ECM
to off.
---------------------------------------------------------------
19. Faxing High Resolution Pages
When faxing high resolution pages, the text received will be
distorted if both the sending and the receiving modem do not
use High Resolution Mode.
---------------------------------------------------------------
20. Using Automatic Credit Card Dialing
When you enter the dial string for a credit card call, place an
ampersand (&) at the end of the credit card number, before the
phone number.
---------------------------------------------------------------
21. If Your Modem Won't Answer a Data Call
Most communications software packages allow you to select one
of the following ways to answer a call: "detect fax & data",
"data only", "fax only", and "ignore ring". If you're using
RapidComm software and have "detect fax & data" selected, if
your modem won't answer data calls, set the answer mode to
"data only".
---------------------------------------------------------------
22. If You Get a General Protection Fault
General protection faults (GPF) usually occur when insufficient
memory is allocated by the computer to perform a task. If you
get a general protection fault while using your modem, do one or
more of the following:
- Be sure your computer meets the minimum memory requirements
for this modem. They are:
At least a 486 laptop
At least a 50 Mhz processor
At least 8 megs of RAM
At least 3 MB of free hard disk space
- Be sure your COM port or IRQ setting doesn't conflict with
any other devices on your computer
- Remove and reinsert the modem in the slot to be sure it's
seated correctly and securely
- Uninstall and reinstall your modem
- Free up memory by closing open applications until no more
GPFs appear.
