i. PnP modem installation

    Before installing PCtel modem drivers, the PnP ISA Enabler driver must
be installed. The driver library on the Windows NT 4.0 CD-ROM includes the
PnP ISA Enabler driver, which will allow the detection and installation of 
Plug and Play devices in Windows NT 4.0. Install the PnP ISA Enabler 
driver (PNPISA) using the following steps:

NOTE: Although Windows NT includes PNPISA to detect Plug and Play 
devices, Plug and Play devices are not supported in Windows NT 4.0. 
PNPISA is provided as a "use at your own risk" tool. 

    1. Locate the "Pnpisa.inf" file in the Drvlib\Pnpisa\x86 folder on the 
Windows NT 4.0 CD-ROM. 

    2. Use the right mouse button to click the "Pnpisa.inf" file, and then click 
"Install" on the menu that appears. 

    3. Restart the computer. 

    After you restart your computer, you may receive a message that 
Windows NT has detected your Plug and Play device(s). If your Plug and 
Play modem is not detected try installing PNPISA again, unplug your 
modem card, reboot your computer and try again.

    When the modem has been detected, use the following steps:

    1. Install the new device from the modem driver disk.

    2. When Windows NT finishes the modem setup, restart the computer.

"Windows NT Diagnostics" in the Administrative Tools to browse resources. 

    3. Go to "Control Panel" and click on the "Modems".

    4. Add a new modem from the "MDMCHPIV.INF" file on the driver disk and
attach the modem to the port that you have just added.

    5. When Windows NT finishes the modem setup, return to the "Control Panel".

    4. Open the "Resources" property sheet. Write down the "Interrupt 
Request" and "Input/Output Range" settings assigned to the modem (The IRQ 
and I/O address will be used later in the installation).
    5. Click on the "Ports" in the "Control Panel".
    6. Click "Add" button to add a port and use the I/O resources you wrote 
down in step 4 for the new COM port. When finished, click "OK".  (NOTE: 
You may see a message saying to restart Windows for the new COM port 
changes to take effect.  If this happens, click "Don't Restart Now!")
    7. Return to the "Control Panel" and select the 'Modem'.
    8. Add a modem and do not allow Windows to detect the modem.
    9. Under "Install New Modem", click "Have Disk" button.
    10. Insert your Windows NT Modem Installation Diskette into the floppy   
drive and click 'OK'.
    11. Select the 'HSP PCMCIA MODEM' from the modem list and click "OK".
    12. At the next screen, attach the modem to the COM port you created in 
step 6, then click "next".
    13. When Windows NT finishes the modem setup, return to the "Control Panel".
On the menu bar, click "View" and then click "Refresh".
    14. Within the "Control Panel", select the "PCtel Port".
    15. Select the COM port attached to your modem and the click "OK".
    16. Remove the modem from the computer.
    17. Shut down your computer.

files, then try again.
