======THE PCMCIA INSTALL PROGRAM README FILE====== 4/15/97

PCMCIA cards allow your computer to recognize a PCMCIA card when it is
installed in a PCMCIA slot. This is accomplished through an embedded "Card and
Socket Services" software.

Once you have installed your modem, you need to use the PCMCIA Install
Program. This software does the following:

* Determines if your computer has Card and Socket Services software.

* If your computer does not have its own Card and Socket Services software,
you can use the PCMCIA Install Program, instead.

* If you are using the Windows 3.1 environment and you want to communicate at
speeds greater than 19,200 bit/s then you need use the PCMCIA Install
Program and install the High Speed Support driver (even if your computer has
Card and Socket Services).



======INSTALLING THE PCMCIA INSTALL PROGRAM======

Step 1:
Insert the PCMCIA Install Program diskette into your computer's disk
drive.

Step 2:
Type A: and press Enter.

Note: A: is only an example. If you placed the diskette in the B drive you
would type B:, etc.

Step 3:
Type Install and press Enter.

The software determines if your computer has Card and Socket Services.

If You Have Card and Socket Services, a main menu displays with the following
Installation Options:

* Install Software
* Install High Speed Support
* Exit Program

If You Do Not Have Card and Socket Services, a main menu displays with the
following Installation Options:

* Install Software
* Configure PCMCIA Modem
* Activate Modem
* Deactivate Modem
* Exit Program

Step 4:
Move the highlighted bar to Install Software and press Enter.

The PCMCIA Install Program prompts you for the location on your computer of
the new files and installs to the subdirectory EZUTIL, unless you specify
otherwise.

Step 5:
Press Enter. The name of each file displays as the PCMCIA Install Program
copies the file to your hard drive.

A dialog box lets you know when the installation is complete.

Step 6:
Press any key to return to the main menu.



======IF YOU DO NOT HAVE CARD AND SOCKET SERVICES======

===Configure PCMCIA Modem===

Step 1:
From the main menu, select Configure PCMCIA Modem.

The configuration displays with the following options:

Left Side Options
The options on the left side of this dialog box (COM Port, I/O Port, IRQ, Memory
Address, and Slot) can be changed using pop-up menus.

Right Side Options
The options on the right side of this dialog box can be changed using the spacebar.

Step 2:
Move the highlight bar to the option you would like to change and press the space bar to
select or deselect an option. The options are:

* COM Port
This required parameter specifies the modem's COM port. The available options are
COM1, COM2, COM3, or COM4. COM 2 is the default.

* I/O Port
This optional command specifies the COM port is a three-digit hexadecimal address.

* IRQ
This option specifies the IRQ Address, used by the COM port. X can be 2, 3, 4, or 5.

* Memory Address
This optional command specifies the starting address of the memory window segment. The
default address is D000 (hex).

* Slot
If your computer has two PCMCIA slots, this specifics the intended slot for your modem.
The options are Slot A and Slot B. Slot A is the default.

* Quiet
Toggles the sound. Default is speaker on.


* Toshiba, Sharp, Data-book
Specifies the PCMCIA Controller type. You can only select one of these options at any
time. Always try the generic driver before using the controller options. The options are:

        * Sharp*
        * Toshiba*
        * Databook (or DATABOOK =xxx, where xxx is the starting address).
          Databook uses a pop-up menu.
        *Toshiba T3300, and Sharp 6700, 6800 notebooks only.

Step 3:
For pop-up menu options (left side), strike any key to bring up the pop-up menu options.

For spacebar options (right side), press the spacebar to turn the option on or off. A
checkmark or diamond indicates that an option is on.

Step 4:
Either change additional settings or click Accept.
If you do not want to save your configuration settings, click Cancel.


===Activate Modem===
Step 1:
From the main menu, select Activate Modem to turn your PCMCIA modem On.

===Deactivate Modem===
Step 1:
From the main menu, select Deactivate Modem to turn your PCMCIA modem Off.

===Exit Program===
Step 1:
From the main menu, select Exit Program.

Step 2:
The software will prompt you for confirmation. Select Yes to exit.



======TROUBLESHOOTING======

===Memory Conflict===
When configuring the modem, EZCONFIG must allocate a 4KB memory window in your
PC's address space. Currently, this window starts at address D000 hex by default. The PC
only uses the first 2KB of this memory window, however, 4KB is the smallest memory
segment that can be decoded by many PCMCIA controllers. The use of this memory area
may conflict with existing software or devices already installed in your PC or laptop (e.g.
Network cards), in which case selection of a different memory area using the "START"
command line argument will be necessary.

EMM386:

Whenever the EMM386.EXE device driver is used, a four-kilobyte  (4KB) portion of the
memory must be set aside for use by the  EZCONFIG modem enabler. This is
accomplished by excluding  the desired hexadecimal address range through the x=mmmm-
nnnn  switch where mmmm-nnnn is a valid memory address range.

For example, memory range D000h to D1FFh is excluded by EMM386.EXE in the
following CONFIG.SYS file:

        DEVICE=C:\DOS\HIMEM.SYS
        DEVICE=C:\DOS\EMM386.EXE X=D000-D1FF
        DOS=HIGH
        FILES=30
        BUFFERS=20

If a different address range is specified through the START=nnnn  argument of the
EZCONFIG.EXE utility, then the same address range  must be excluded by EMM386.EXE.
For example if START=CC00 is  used, the above CONFIG.SYS file should appear as
follows:

        DEVICE=C:\DOS\HIMEM.SYS
        DEVICE=C:\DOS\EMM386.EXE X=CC00-CFFF
        DOS=HIGH
        FILES=30
        BUFFERS=20

Quarterdeck QEMM386:

When using the QUARTERDECK QEMM386, in order to set aside the  four kilo-bytes
(4KB) of memory needed by the EZCONFIG.EXE program  the EXCLUDE=mmmm-nnnn
switch must be used. For example, memory address range of D000h to D1FFh is set aside
in the following CONFIG.SYS file:

        DEVICE=C:\DOS\HIMEM.SYS
        DEVICE=C:\QEMM\QEMM386.SYS EXCLUDE=D000-D1FF
        DOS=HIGH
        FILES=30
        BUFFERS=20

===IRQ Conflicts===

Also note that the potential for IRQ conflicts exists. Because the communications UART
(the COM port) is internal to the modem, you must ensure that the PC's COM port 'x' is
disabled before attempting to execute EZCONFIG COM.

If your PC does not have a physical COM2 port, you can execute the "EZCONFIG COM2"
command line because the modem provides the COM port when inserted.
