1. INTERNAL MODEM INSTALLATION
1.1 Introduction
The principal consideration when installing an internal modem is to avoid system
resource conflicts, that is two devices simultaneously trying to use the same bytes in the
I/O address space or the same Interrupt Request line (IRQ). An internal modem looks like
a serial I/O (COM) port to the computer. It can be installed as an extra COM port, or
replace an existing COM port, which must be disabled or removed. The same
consideration applies if you are installing any COM port, including installing a serial port
card. A standard COM port uses 8 bytes in the I/O address space and one IRQ line.
An external modem requires an existing COM port to be available for connection to the
modem; whereas an internal modem has its own COM port built in. There are two points
to be considered when installing any COM port:

What COM ports already exist within my computer and therefore what may I install
my new port (internal modem) as? That is, what I/O address space is free?

What interrupts are available for use with a new port? That is, what IRQs are free?
These two questions are addressed in the following sections.
1.2 Plug and Play
Windows 9X has a system for automatically selecting the COM port and IRQ which your
internal modem uses, known as “Plug and Play”, or “PnP” for short. A special PnP chip
on the modem provides the capability. The alternative to PnP is to manually set the COM
port and the IRQ with jumpers. A jumper is a tiny shorting link which can be placed over
two adjacent square pins, thereby connecting them together. The square pins (usually
gold) stick out of the printed circuit board (PCB) which the modem is constructed on.
Jumpers are usually black plastic on the outside, gold-plated metal on the inside.
Some modems have only PnP with no capability to be set with jumpers. Some have only
jumpers with no PnP capability. Some modems may be switched between the two
possibilities with yet more jumpers, they can use either PnP mode or jumper mode. If
there are 9 square pins with 3 jumpers, in the middle of the modem PCB, labelled “J5 J3
J4”, then the modem can be switched between PnP mode or jumper mode. See below for
a diagram. Orient the PCB with the gold fingers (where it plugs into the computer) at the
bottom.
1.2.1 To Select PnP Mode
Put the jumpers horizontally between the two columns labelled J3 and J4. Also set the
IRQ jumper on the row labelled PNP. Once you have PnP mode selected, Windows will
automatically select a COM port address and IRQ. Occasionally, you might not agree
with the COM port or IRQ settings decided by Windows. Those settings can be changed
in the Device Manager, see the section “Configuring Software” below.
1.2.2 To Select Jumper Mode
Put the jumpers horizontally between the two columns labelled J5 and J3. Set the IRQ
jumper to whatever IRQ number you wish to use. See “Selecting and Setting an Interrupt
3
Maestro Pty Ltd
(IRQ)” below for a discussion on which IRQ to select. Also select the COM port, see
next section.
Location of jumpers on PCB
1.3 Selecting a COM port
Most IBM compatible computers already have two existing COM ports: COM1 and
COM2. You need know whether these ports exist. The simplest way of finding out is to
re-boot your computer and, if your BIOS reports the available ports, simply record the
reported addresses. BIOS types such as American Megatrends Inc. (AMI) report the
current hardware configuration at startup. Note that I/O addresses are normally given in
hexadecimal. The standard I/O addresses for serial COM ports are:
Port
COM1:
COM2:
COM3:
COM4:
I/O Address
03F8 - 03FF
02F8 - 02FF
03E8 - 03EF
02E8 - 02EF
Some or all of these ports may be reported by your BIOS when you first boot your
computer. Addresses are often given as just the lowest address, without the leading zero,
rather than the whole range. If all the above addresses are reported, then you will have to
consult the documentation which came with your computer hardware and disable one of
the ports. Your internal modem is only capable of being configured for one of the above
I/O addresses.
If any one or more of these addresses is not reported, your modem should be installed as
the next available port. As an example, if your BIOS reports addresses 3F8 and 2F8 as
4
Jetstream Series 2 Internal ISA
being used, then COM1 and COM2 are already present and you should install your
modem as COM3 (3E8). As discussed in the next section, consideration should also be
given to the selection of the interrupt request (IRQ) used.
Windows 95/98/ME/2000 will report system resources used in the Control Panel, System,
Device Manager. Click on Computer, then Properties. You will see an overall summary
of the system resources used in the computer. To see the resources used by a particular
device, click on the particular device (for example, COM2), then Properties, Resources.
Another method for determining the currently available COM ports is by using diagnostic
software. Microsoft's MSD is one such example of a program which will report the
existence or otherwise of hardware, such as COM ports, printer ports and disk drives. In
MSD, select the “COM Ports” option from the main screen menu and record the ports
and addresses already being used; remember that you may select any one of the above I/O
addresses for your modem, so long as it is not already being used.
There are other ways of finding which COM ports are being used, any method which
works reliably will do. You could run other diagnostic programs, for example MSINFO
or DEBUG (for advanced users only). Reading your computer documentation or asking
your dealer might help.
Be aware that some video cards have a conflict with the standard COM4 I/O address. The
video cards which are known to cause problems are those based on the S3, 8514A and
ATI mach8 chipsets. This may not be an exhaustive list, so be careful anyway if you do
not seem to have any of these chipsets on your video card. Diamond Stealth and Number
Nine are two brands which exhibit this problem. If you have a conflicting video card, the
I/O address given above for COM4 should be avoided at all costs.
After you have followed the instructions on “Setting Your COM Port” as detailed in the
next section, the methods above may later be used to determine if your modem
installation has been successful. Try any of the above methods above to select your next
available port and then continue reading.
1.4 Setting your COM Port
If you do not have a device (such as a mouse or printer) plugged into a COM port which
already exists, the port is still active and its I/O address can not be used by another
device.
The I/O address for your modem is selected using jumpers labelled “COM SEL”. The
jumpers go horizontally, one jumper in each row. The rows are labelled J6 and J7.
The following table shows the jumper settings to select the I/O address for your modem.
J6
1-2
2-3
1-2
2-3
J7

COM2
COM3
COM4
Address
3F8
2F8
3E8
2E8
Set the jumpers on your modem now and read on.
1.5 Selecting and Setting an Interrupt (IRQ)
The next important decision when installing your internal modem is selecting which
interrupt request (IRQ) to use for the modem. There are generally several IRQ lines
Maestro Pty Ltd

available for a new modem to use but you should select carefully. Devices which are in
use inside your computer will each be using an IRQ and there is a limited number
available. Devices such as existing ports, sound cards, disk adaptors and multimedia
cards all use IRQs to attract the attention of the central processor.
There are nine selectable IRQs you can use with the modem, these are IRQs 3, 4, 5, 7, 9,
10, 11, 12 and 15. COM1 and COM3 sometimes both use IRQ4. COM2 and COM4
sometimes both use IRQ3. We do not recommend that you have two devices using the
same interrupt or you may experience problems. If you already have COM1 and COM2
then IRQs 4 and 3 are not really available for use; you are therefore restricted to using
IRQ5, 7, 9, 10, 11, 12 or 15.
Select an IRQ which is not being used by any other I/O device. Notice that some older
MS-DOS modem-related software will not allow you a free choice of IRQ. If you use
such software, you will need to know which IRQs you are able to select. Once certain as
to which IRQ you wish to use, set the IRQ jumper on the PCB.
Turn the computer off and insert the modem into an available slot in your computer. The
modem will fit into any IBM-compatible ISA 16-bit or VESA slot. Make sure the modem
is plugged in properly. Check that the little gold fingers on the modem line up nicely with
the gold contacts on the main board. Then turn your computer on. Use the procedures in
the section above, titled “Selecting a COM Port”, to determine if your installation was
successful.

4. OTHER INFORMATION
4.1 Using a Plug and Play modem in DOS and Windows3.1
There is a program called “setmae.exe” which will allow the use of of a Plug and Play
modem in a Non Plug and Play DOS enviroment. For example, MS-DOS and Windows
3.1. This program is available on the Maestro CD-ROM in the folder \Msdos. It is also on
the Maestro website, click on Support, List, MS-DOS then download the file.
To install this program do the following: Get to a DOS prompt. Using the CD command,
change to your root directory or some directory on your path. If necessary, please see
your DOS documentation for an explanation of the terms “path” and “CD command”.
Then issue the command:
copy D:\msdos\setmae.exe
NOTE: The D: should be changed to the letter of your CD-ROM drive.
Then do:
setmae
8
Jetstream Series 2 Internal ISA
The Setmae software will attempt to probe the PnP chip on the modem. After probing, it
will then attempt to find a free IRQ and I/O address to set the modem to. If it is
successful, you can press Enter to accept the values. If the values are not acceptable to
you, then press TAB to select the "Manual" or "Cancel" button. To adjust settings
manually use the TAB key to select the different fields and the up-down arrow keys to
change the settings within fields. When you accept the settings from automatic or manual
selection, the program writes a line to the "AUTOEXEC.BAT" file in your root directory.
The format for this line is:
SETMAE <I/O Address> <IRQ>
If setmae selected the IRQ and I/O Address for COM1, then the line would look like this:
SETMAE 3f8 4
If you want to change the settings later, you must delete or modify the old entry in the
"AUTOEXEC.BAT" file.
4.2 Initialising the modem
The modem needs to be initialised before most actions. In most systems, this is done by
the modem driver and you never need to worry about it. However, some systems use an
initialisation string. If your software asks for an init string, then use the following:
AT&F T &D2 S91=14 S95=1
4.3 Internet Setup
Once you have the modem connected and the drivers installed, then you need an Internet
Service Provider. An ISP’s disk may accompany this modem. You can use this disk or
choose your own at your discretion. If you have trouble with the ISP’s disk, then you
will need to contact their technical service. Once you have an ISP and have opened an
account with them, then they should provide you with the appropriate instructions to
make an internet connection to them.
4.4 Fax/Voice Software
The Maestro CD contains fax/voice software called ‘PhoneTools’, however you can use
any fax/voice software you want with this modem. If you are only going to use your
modem for Internet access, then you do not need to install this software.
To install: Run Setup in the PhoneTools Folder on the Maestro CD-ROM.
