Refer to Chapter 8 to continue the installation of the modem

7.2 FOR WINDOWS 3.1x or DOS

Turn your computer on and go to the "C" prompt (C:\>).

If you have MS-DOS 6.0, or higher, or MS-Windows 3.1x, type MSD (Microsoft Diagnostic)

at "C" prompt. This will not work if you only have Windows 95, (see above section).

MSD is going to give you information on your computer system. Look and see if you

can locate an entry call "COM Port." There should be a number right next to that entry

identifying the number of COM ports you have. Write the number down on a piece of

paper.

Press "C" to go into the COM Port screen.

Write the port addresses for each COM Port down. Regardless of what MSD says,

"03F8" is COM1, "02F8" is COM2, "03E8" is COM3, and "02E8" is COM4. If it has

"02E8" under COM3, don't worry about it. It just means you skipped a COM Port, this is

very common. You only have to go by the port addresses.

OPTION 1

If you only have "03F8" in the COM Port screen and do not have any sound card, network

adapter, scanner card, bus mouse, or other device using IRQ3, set your modem's

switches or jumpers to COM2 IRQ3 according to the user's manual that cames with your

modem (both COM and IRQ must be set). If you only have "02F8" for COM port, set

your modem to COM1 IRQ4, again following the directions of your Modem User's manual.

OPTION 2

If you have both "03F8" and "02F8" and do not have any sound, network, scanner card,

bus mouse, or other device using IRQ5, set your modem to COM3 IRQ5.

OPTION 3

If you have "03F8" and also have "02E8" and you do not have any sound, network,

scanner card, bus mouse, or other devices using IRQ5, set your modem to COM2 IRQ5.

OPTION 4

If you have "03F8" and also have "02E8" and you do have another device using IRQ5,

please consult your "Multi I/O Card User's Manual" and have COM4 "02E8" IRQ3

disabled. This "Multi I/O Card User's Manual" ought to come with your computer system.

Check with your computer dealer if you can't find one in the package. Set your modem

to COM2 IRQ3 after COM4 IRQ3 is disabled on the I/O card.
