1. Installing Your Modem
When installing your modem, insert the Modem Installation
Diskette and click Start > Run > A:\SETUP. Insert the
modem when prompted.
----------------------------------------------------------------
2. Installing Your Modem on an HP Omnibook 800CS or an NEC 6030
If you are using an HP Omnibook 800CS or an NEC 6030 computer,
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 Disk. After the computer has rebooted and you
hear the tones indicating the modem is inserted, run A:\SETUP
from the Modem Installation Disk to copy necessary files to
your computer.
----------------------------------------------------------------
3. Installing in Windows NT
Refer to the online Modem User Guide for Windows NT installation
instructions.
----------------------------------------------------------------
4. About the DOS Enabler
Note
If Card and Socket Services are installed on your computer, we
recommend that you run Setup from Windows rather than Enable
from DOS. Setup detects how C&SS will enable your PC Card, and
also determines what resources are available on your
computer. If you use the DOS Enabler, in many cases you must
determine what COM port and IRQ to assign to your PC Card.
ENABLE.EXE can be run from the DOS prompt or from your
AUTOEXEC.BAT or CONFIG.SYS file. ENABLE.EXE will use the
default values specified in the ENABLE.INI file, but you may
change any or all of the default settings when you run Enable
by using the following switches:
Switch Description
/Cn Indicates the COM port that you want the modem to
use. You may use 1 through 4, or you can remove
the switch to have Enable choose the first
available port.
/Dnnnn Indicates a delay in milliseconds that the driver
waits to initialize the Card. It is needed only
for machines with a Ricoh PCMCIA controller, such
as the IBM 360 and the IBM 755. A good value to
use is 500.
/H or /? Displays a help screen.
/In Indicates the modem interrupt (IRQ) you will use,
where n indicates the interrupt level. The value
of n can be 3, 4, 5, 7, 9, 10, 11, 12, or 15.
3 and 5 are good choices. If you are using COM1
or COM3 for your modem, the default IRQ is 4. If
you are using COM2 or COM4, the default IRQ is 3.
Your Megahaertz modem can use any IRQ that is
available. The configuration of your computer
determines which IRQs are available.
/Pnnnn Indicates the starting memory address for the modem.
Values of nnnn can be C000h to EF00h in 100h
increments. The default is D000h. You must
exclude the same memory range on the memory manager
line in the CONFIG.SYS file. C800h-C8FFh or
D000h-D0FFh are good choices.
/Sn Indicates the PC Card slot the modem is in, where n
can indicate slot A through H. The default is A
(there is no standard about which slot is A and
which is B when two slots exist. You may need to
experiment to find out). If no slot is specified,
Enable will cycle through all the PC Card slots.
/Un Disables the slot the modem is in, where n can
indicate slot A through H. It removes Enable's
information from the computer and turns off
the power to the modem. If no slot is specified,
all slots are disabled.
For example, to indicate that you want to use COM4 and Slot B,
you would enter the following statement at the DOS prompt:
ENABLE /C4 /SB
To add the enabler to your CONFIG.SYS file, follow these steps:
1. At the DOS prompt (C:>), enter MD \MHZ to create an
MHZ directory on your hard drive.
2. Insert the Modem Installation disk into the floppy drive.
3. At the DOS prompt (C:>), type COPY A:\ENABLE.* C:\MHZ
and press Enter. This copies ENABLE.EXE and ENABLE.INI
to the C:\MHZ directory.
4. Use a text editor such as EDIT to add the following two
lines to the END of your CONFIG.SYS file:
[COMMON]
DEVICE=C:\MHZ\ENABLE.EXE
[COMMON] is needed only if you are using DOS 6.0 or later
(type VER at the DOS prompt to see what version of DOS you
are running).
This will allow Enable to run every time you reboot your
computer.
5. Using a text editor such as EDIT, modify the Memory= line
in file ENABLE.INI that you copied to your hard drive.
Memory specifies the memory location to be used to enable
the Card. If you are using Card and Socket Services,
specify the same address that it uses. If you are using
ENABLE.EXE, exclude the memory range you will use with your
memory manager. You should exclude a 4K block of memory.
For example, if you were using memory location D000h,
you could exclude the 4K block for EMM386 by specifying the
desired value of X=D000-D0FF to the appropriate line in
your CONFIG.SYS. For example:
DEVICE=C:\DOS\EMM386.EXE NOEMS X=D000-D0FF
Congratulations! Your modem is installed. Now connect the
cables and set up your communications software.
----------------------------------------------------------------
5. If You are Having Trouble Connecting
If you're having problems connecting with your modem, verify
that the modem initialization string in your communications
software contains AT&F0 (hardware flow control). If you are
having problems connecting internationally, see the Country
Configuration table in the Modem User Guide for helpful
information.
---------------------------------------------------------------
6. Setting the Number of Rings Before Answering
On incoming calls, the modem uses the first ring to come out
of low power mode. For this reason, set ATS0=1 to answer on
the second ring.
----------------------------------------------------------------
7. Using Pulse Dialing
Your modem always defaults to tone dialing when using only the
ATD command. If you want to pulse dial, use ATDP.
---------------------------------------------------------------
8. If You are Using a Texas Instruments Notebook with a
Phoenix Card Manager
At ship time, there were known issues with modem functionality
in a Texas Instruments notebook using a Phoenix card manager,
such as TI Extensa and TI TravelMate. For help, call the
support phone number for your notebook, or access www.acer.com.
---------------------------------------------------------------
9. If You are Using an IBM 760C or an IBM 365XD Computer
If you have a problem with modem operation after the computer
has reactivated after going into sleep or suspend modes, leave
the computer running and remove and reinsert the modem.
---------------------------------------------------------------
10. If You Don't Hear Sounds During Faxing
When faxing with RapidComm software, you may not hear any
sounds during the faxing process. If this happens, go into
RapidComm modem setup and set the volume to medium (refer to
the RapidComm User's Guide for more information).
---------------------------------------------------------------
11. Using Your Modem in New Zealand
There are some differences in the way the User Guide states to
use the modem and using the modem in New Zealand. They are:
a) To disable call waiting in New Zealand, pre-pend your
dialing string with "*52".
b) Long distance calls in New Zealand are prefaced with
0 + area code (00+ country code+ area code for
international calls)
c) It is almost universal to dial 1 for an outside line from a
PBX in New Zealand.
d) Caller ID support and decadic pulse dialing (ATDP) are not
available in New Zealand.
---------------------------------------------------------------
12. New Zealand Regulatory Notes
NOTES FOR USE OF THIS DEVICE IN NEW ZEALAND
The grant of a Telepermit for a device in no way indicates
Telecom acceptance of responsibility for the correct operation
of that device under all operating conditions. In particular
the higher speeds at which this modem is capable of operating
cannot always be expected on a network designed to deliver
voice telephony to customers. Failure to operate should not be
reported as a fault to Telecom.
In addition to satisfactory line conditions a modem may only
work properly if:
a) it is compatible with the modem at the other end of the call
and
b) the application using the modem is compatible with the
application at the other end of the call - e.g. accessing
the Internet requires suitable software in addition to a
modem.
This equipment shall not be used in any manner which could
constitute a nuisance to other Telecom customers.
Some parameters required for compliance with Telecom's PTC
Specifications are dependent on the equipment (PC) associated
with this modem. The associated equipment shall be set to
operate within the following limits for compliance with Telecom
Specifications:
a) not more that a total of 10 call attempts shall be made to
the same number for any single manual call initiation within
a 30 minute period.
b) There shall be at least 60 seconds between call attempts to
the same number.
c) Automatic calls to different numbers shall be not less than
5 seconds apart.
NOTE THAT FAULT CALLOUTS CAUSED BY ANY OF THE ABOVE CAUSES MAY
INCUR A CHARGE FROM TELECOM.
