===========================================================================
The purpose of PCMCIA is to allow your laptop or PC BIOS to recognize a
PCMCIA card when it is installed in a PCMCIA compatible slot. This can
or will be accomplished through an embedded "Card and Socket Services"
software.
If your system utilizes Card and Socket Services, there will be no need for
programs such as EZCONFIG.EXE (or INSTALL.EXE) which act as direct PCMCIA
card enablers.
In the event that your notebook computer or PC does not include Card and
Socket Services software, you may be able to upgrade your BIOS to a more
current revision by contacting the manufacturer of your PC, or by
requesting Card and Socket Services software.
===========================================================================
INSTALLATION OF UTILITIES
The floppy disk shipped with the modem contains utility software which will
default to installation onto the "C:" hard disk drive. However, you can
choose any drive by changing the default installation drive. You may
initiate installation by following these directions.
Assuming the floppy diskette is placed in drive A: (or B:)
C:\> A: <Enter> (or B: <Enter>)
A:\> INSTALL <Enter>
This action will create a new directory called C:\EZUTIL and automatically
copy all files on the floppy diskette to that directory.
Please add C:\EZUTIL to your PATH environment variable or copy EZCONFIG.EXE
to a directory which is already in your PATH.

HAYES CONFIGURATION PROGRAM - USER'S GUIDE
(EZCONFIG Version 1.14)
In the event that your system is not equipped with Card and Socket Services
software which helps the system in supporting automatic recognition of the
card, you may have to execute the supplied EZCONFIG program.
Before a Hayes Microcomputer Products, Inc. PCMCIA modem can be used
with a communications application, it must be configured. The modem can
be configured for use on COM1, 2, 3 or 4, using the Hayes Configuration
Program, "EZCONFIG" or (INSTALL.EXE). Note that this configuration program
must be executed each time the modem is inserted into the PCMCIA slot, if
Card and Socket Services software is unavailable.
You can create a custom batch file containing EZCONFIG, and all the needed
parameters to enable the modem through the INSTALL.EXE program. (Please
refer to Chapter 4 of the Operating Manual for more information.)
Remember, you must run this batch file, MODEM_ON.BAT, (or EZCONFIG COMx)
each time the modem is inserted into the PCMCIA slot, to ensure proper
configuration of the modem. Failure to do so will result in the
communications application being unable to access the modem. (AT
commands will not function.)
You can create another batch file to automatically execute MODEM_ON.BAT
(EZCONFIG COMx) each time a communications application is loaded. The
following is an example:
e.g. COMM.BAT
+--------------------+
|CALL MODEM_ON.BAT |
|COMMAPP.EXE <------ Your communications application
|EZCONFIG OFF |
+--------------------+
The EZCONFIG program requires at least one command line argument which directs
the laptop to find the modem in COM1, COM2, COM3, or COM4. If no arguments
are supplied, the EZCONFIG program will display a list of valid options.
Additionally, if your PC was manufactured by TOSHIBA* (T3300 model only) or
SHARP* (6700 and 6800 series only) or incorporates a Databook* PCMCIA
controller circuit, you must inform EZCONFIG by stating your PCMCIA
controller type as a command line argument.
To obtain on-line help type: EZCONFIG HELP.
COMMAND LINE ARGUMENTS
----------------------
This section briefly describes command line arguments, and the effect they
will have with relation to EZCONFIG and the laptop.
Command Format:
EZCONFIG COMx|OFF [PORT=xxx] [IRQ=x] [START=xxxx] [SLOTx] [QUIET] [MON]
[CONTROLLER[=xxx]] [BAUDx]
COMx This parameter is required. Specifies COM port,
where x is 1,2,3, or 4.
OFF Turns power to the modem OFF.
PORT=xxx Specifies the COM port three digit hexadecimal address.
If this parameter is left out, default COM port address
values are used. These default values are as follows:
COM Port Port Address (Hexadecimal)
-------- --------------------------
1 03F8
2 02F8
3 03E8
4 02E8
IRQ=x Specifies IRQ used by the COM port, 'x' can be 2, 3, 4, or 5.
If this parameter is left out, default COM port IRQ
assignments are used:
COM Port IRQ
-------- -----
1 4
2 3
3 4
4 3
START=xxxx The memory window that is mapped onto the modem card
normally starts at segment D000h and is 4 KB in size
(only 2 kB are required by the modem). If this range
conflicts with other hardware, you can specify a new
starting segment using 4 hexadecimal digits. Do not
leave any spaces around the '=' sign.
SLOTx Specifies the PCMCIA slot in which the modem resides,
where 'x' is either 'A' or 'B'. The default is 'A'
which is consistent with a single-slot PC.
QUIET Toggles the state of audio. The default value is speaker ON.
The modem M0, M1, M2, and M4 commands also allow you to
change the state of the speaker. Please see your
Operating Manual for information on these commands.
MON Displays diagnostics information on the progress of EZCONFIG.
CONTROLLER Specifies the PCMCIA Controller type. The following are
possible options:
SHARP* Use this if your PC was manufactured by Sharp.
The Sharp PC-6700/6800 series of notebooks require
this parameter.
TOSHIBA* Use this if you have a Toshiba T3300SL*. Please
note that this command line argument is NOT
necessary when using a TOSHIBA T1900*, T4500*,
T4600*, T4700* or a later Toshiba* computer.
DATABOOK* Use this parameter if your computer utilizes the
Databook* controller circuit. Please note that in
all cases your computer should also include
Databook* Card and Socket services software which
provide automatic recognition. Therefore, EZCONFIG
should be used in rare cases where the use of Card
and Socket services software is not possible.
The Databook*=xxx parameter could be used to
specify the controller I/O address.
BAUDx Specifies the baud rate multiplier, where 'x' is either '0'
or '1'. When the value of 'x' is equal to '1', the specified
DTE or Baud Rate set in your communications software will
be doubled by the modem's UART. Thus, a DTE speed of
115,200 bps will result in a 230,400 bps speed between the
computer and the modem. A DTE speed of 19,200 bps will
result in a 38,400 bps speed between the computer and modem.
If 'x' is equal to '0', the DTE speed will be equal to that
set in your communications package.
Examples:
---------
1. EZCONFIG COM2
Configures the modem on COM2, setting the memory window starting address
to D000h (default). Speaker is enabled. Generic controller interface is
assumed.
2. EZCONFIG COM2 IRQ=5 PORT=240
Configures the modem on COM2, using port address 240 (hex) and IRQ 5.
The speaker is enabled and a generic controller interface is assumed.
3. EZCONFIG COM3 DATABOOK=240 QUIET
Configures the modem on COM3. A Databook* PCMCIA controller at interface
I/O address 240 (hex) enabled. The speaker is turned off.
4. EZCONFIG OFF
Turns off all power to the card. The card is disabled.
5. EZCONFIG COM4 SHARP START=D600 BAUD1
Configures the modem on COM4. A Sharp* PCMCIA controller is enabled.
Memory window is set to start at D600 (hex). Clock doubling is enabled.
6. EZCONFIG COM4 IRQ=2 MON
Configures the modem on COM4 and IRQ 2. The speaker is enabled and a
generic controller interface is assumed. The MON parameter enables
EZCONFIG to display progress information helpful for debugging.
Note: Command line arguments are processed from left to right,
in order to mix & match commands that make sense.
MEMORY CONFLICTS
----------------
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<x>. 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.
COMM DRIVERS
------------
Hayes PCMCIA modems include an enhanced 16550 UART that
provides a 64 byte FIFO and automatic RTS. To enable these
features under Windows with Quick Link II Fax for Windows Software, a
special comm driver has been included on this disk. This driver is named
SMSICOMM.DRV. To install the new driver, perform the following steps:
1. Copy SMSICOMM.DRV to C:\WINDOWS\SYSTEM
If your Windows directory exists on a different drive than
C:\, substitute the appropriate drive desgination.
2. Open the SYSTEM.INI file in the C:\WINDOWS subdirectory in
any standard text editor such as DOS Edit or Windows Notepad.
3. Locate the comm driver designated "comm.drv="
In most cases, this line will appear as:
comm.drv=comm.drv
4. Edit this line to read:
comm.drv=smsicomm.drv
5. Some software packages turn the FIFO buffer off through the following
line in the SYSTEM.INI file [386 Enh] section in your Windows
directory:
COMxFIFO=0
Here 'x' is 1,2,3, or 4 (example COM2FIFO=0). If this line is present in
your SYSTEM.INI (under the [386Enh] heading), then in order to enable the
FIFO buffer change it to the following:
COMxFIFO=1
If the FIFO buffer is not enabled, you may experience dropped characters
in the data stream or CRC errors during file transfers at high port (DTE)
speeds.
6. To make the above modifications take effect, exit Windows and then
start it again.
