Chapter 3 - Comprehensive Driver Notes

Introduction

This chapter provides general information on the
MT5634ZLX software drivers, as well as specific
information on the NDIS, Packet Driver, and
Windows for Workgroups drivers.

Factory Default Settings

The MT5634ZLX was shipped from the factory with
the following default settings:

Modem COM Port COM3 , IRQ5
LAN IRQ Level 11
LAN I/O Base Addr. 320

Network OS Netware 3.x and 4.x
Frame Type Ethernet 802.2
Target Path C:\NETWARE

Quick Start

For a quick start, simply run INSTALL.EXE, located
at the root directory on the Driver diskette.

PC Card Software - Manual Installation

The installation software has been carefully
designed to detect a combination of hardware and
software installed on the PC. Proper detection
allows the PC’s PC Card drivers to enable the
MT5634ZLX. If the installation software fails, the
enabler must be manually copied from the driver
disk to the PC. If you are using Windows for
Workgroup 3.11, Windows NT, or Windows 95,
follow the instructions for installing PC Cards in your
PC’s manual.

MT5634ZLX Owner’s Manual

32

Determine if any third party generic enablers
installed on the PC. These are identified by a
search through the CONFIG.SYS file for the
following lines:

Vendor Device Loaded in CONFIG.SYS
Awards Software

DEVICE=C:\CARDWARE\PCENABLE.EXE

System Soft

DEVICE=C:\CARDSOFT\CARDID.EXE

Phoenix

DEVICE=C:\PCMPLUS\PCMSCD.EXE

If one of these lines exists in your CONFIG.SYS, it
can be used to enable the MT5634ZLX PC Card.
Follow the PCMCIA driver installation instructions in
the PC’s manual. If the PC Card drivers do not
support multi-function cards, use the Multi-Tech
supplied enabler.

Disable all current PC Card drivers by editing the
CONFIG.SYS and AUTOEXEC.BAT. If it is
necessary to keep these drivers for other adapters,
skip to next section.

1. Insert the Drivers disk in drive A:.

2. Type C: at the command prompt.

3. Type MD LMCARD to make a new directory.

4. Type COPY A:\ENABLER\*.* C:\LMCARD to
copy the enabler to your directory.

5. Modify the PATH= statement in your
AUTOEXEC.BAT to include the path
C:\LMCARD.

6. Change from PATH=<Original Path> to
PATH=<Original Path>;C:\LMCARD

7. Use CARDEN.EXE to enable MT5634ZLX
when the PC is loading Card Services.

33

3 - Comprehensive Driver Notes

Getting Started

For Novell, Lan Manager, and Packet Driver, first
insert the MT5634ZLX PC Card into an open
PCMCIA card slot, and remove all other PC Cards
from your computer. Insert the MT5634ZLX driver
disk into Drive A and type A:\INSTALL at the
command prompt. The installation program will
copy files to the destination directory and modify
your related files (CONFIG.SYS, AUTOEXEC.BAT,
and NET.CFG).

For Windows for Workgroup, Windows NT and
Windows 95, use the

“Network Setup”

utility
provided by Windows system to install the
MT5634ZLX. On this disk you will find sub­directories for each of the Microsoft products. Each
directory has a README.TXT that will help install
that particular Microsoft product.

After installation, reboot your computer to enable
the MT5634ZLX.

Using DOS Extended Memory Managers

Under PCMCIA, all I/O cards (including Ethernet
and Modems) must be initialized as memory cards
and then switched into I/O mode operation by an
enabler software.

Therefore, the enabler software (e.g.,
CARDEN.EXE) must see the PC Card memory
when it is executed. DOS extended memory
managers such as EMM386 and QEMM take control
of the PC memory space which effects PC Card
initialization.

MT5634ZLX Owner’s Manual

34

There are two available solutions:

1) Run enabler (CARDEN or existing PC Card
drivers + CARDEN) before EMM386 or QEMM
is loaded, or

2) Exclude at least 4K of memory from EMM386’s
or QEMM’s use. An exclusion of X=D000­D3FF will work well. There may also be
additional exclusions for your PCMCIA drivers;
don’t modify these.

Driver Directory Structure

The network drivers on this disk is organized in the
following structure. Each directory contains a
README.TXT file which provides detailed
installation instructions for the drivers in that
directory:

CARDEN.EXE Direct PCMCIA Card Enabler for

DOS; supports MT5634ZLX and
Intel compatible, Compaq and
Databook controllers.

LM28ODI.COM MT5634ZLX DOS/ODI Driver

Notes for Windows For Workgroups

After installation of the MT5634ZLX drivers, the
system will automatically update the CONFIG.SYS
and AUTOEXEC.BAT files so that the driver will be
loaded at system startup. When modifying the two
files, the system will make a dual copy named
CONFIG.ABO and AUTOEXEC.ABO in the system’s
directory. If the MT5634ZLX driver is not
successfully loaded, replace the two *.ABO file for a
related file and try to start the system again.

The following are examples of partial CONFIG.SYS
file and AUTOEXEC.BAT for loading System Soft’s

4 - Troubleshooting

Chapter 4 - Troubleshooting

Introduction

This chapter provides general and specific problem
solving steps. Below are a number of examples of
Problems (listed in bold:), Causes (C:), and
Solutions (S:). If your MT5634ZLX is not working
properly, look up the problem and solution here; if
unsuccessful, call Tech Support (see Chapter 5). At
the end of this chapter is some specific steps for
resolving IRQ and COM port conflicts.

No Response to AT Commands
C: The COMx port that the modem is set to may be

used by another card in the computer already.

S: Change the COMx port of MT5634ZLX to a

different unused port. It might be best to set it to
COM3 or COM4. Even if you are not using a
serial port which is set to the same COMx port
as the modem, it can still interfere with the
modem. Be sure to update your software COMx
port setting as well.

C: The Interrupt that the modem is using may be

the same Interrupt that another card is using.

S: Change the IRQ settings to a different, unused,

IRQ. Even if you are not using a serial port
which is set to the same IRQ as the modem, it
can still interfere with the modem.

The Modem Does Not Execute the Command
Line

C: Make sure you are typing

‘AT’

at the beginning

of command line (and hit Enter at the end).

C: Make sure the modem is not in Data Mode.

Type

+++

if necessary.

C: Make sure your software is set to the same

COMx port as your MT5634ZLX.

Occasionally, the Modem Gives a Burst of
Errors.

C: The telephone line may be noisy or bad.
S: Hang up the call and try to connect again for

getting a better telephone line.

C: If there are other telephones on the same line

that your modem is using, someone may have
picked up a telephone on that extension.

C: Your telephone line may have the call waiting

feature.

S: Try adding

*70

to your

ATDT

dialing command
line. If it doesn’t help, ask your telephone
company how to temporarily disable call
waiting.

The Modem Gets Random Errors in
Transmitted Data.

S: Try to use V.42 or MNP1-4 if possible.
S: Connect the modems at a slower baud rate.

MT5634ZLX Owner’s Manual

44

After Downloading a File, the File Does Not Store
on Your Disk Drive

C: If both modems are using MNP or V.42 protocol,

then flow control may not be enabled.

S: Configure your software to use RTS/CTS flow

control to cause your computer to pause long
enough for the file to be stored to disk.

The Text on the Screen Is Not Legible
C: Your software settings may not match the

settings of the remote device.

S: Make sure your data bits, stop bits, and parity

settings match the settings that the other
computer is using. The two most common
settings are: 8 data bits, None parity, and 1 stop
bit (8,N,1) or 7 data bits, Even parity, and 1 stop
bit (7,E,1).

C: If the telephone line is very noisy, you may see

corrupted data on your screen.

C: Due to poor telephone line conditions, the

modem may have fallen back to a slower
communication speed. You may need to change
the baud rate setting in your software to match
this slower speed. To return the modem to the
higher speed, disconnect the link and re­establish again.

When Using V.42bis or MNP5, Some Features
Are Disabled

C: You may be using a non-streaming protocol,

like Xmodem or Ymodem to transfer files.
Those are fine unless you are using V.42bis or
MNP5

S: When using V.42bis or MNP5, you should use a

streaming transfer protocol like Ymodem-G or
Zmodem.

S: Configure your software to use hardware flow

control (RTS/CTS ON).

45

4 - Troubleshooting

When Connecting to Another Modem, the
Modem Reports a Higher Connect Baud Rate
than it Is Really Using

C: The modem defaults to report the modem-to-

computer baud rate when it responds with

CONNECT

.

S: Go to Command mode with your

communication program (like Telix) and type

ATW2

, then press Enter. This tells the modem
to report the modem-to-modem baud rate
instead.

When I Run CARDEN, “PC-Card Is Not Enabled
Successfully” Is Displayed

C: Your computer does not have enough memory

to map the attribute memory of your
MT5634ZLX.

S: If memory management software (e.g.,

EMM386) is installed, you must reserve an area
in upper memory (C000:0 — EFFF:F) for
MT5634ZLX attribute memory when enabling
the card.

Example:

Device=C:\DOS\EMM386.EXE RAM

X=D000-D3FF

Reserve D000 - D3FF for attribute memory.

C: No free I/O space or interrupt request can be

assigned to the MT5634ZLX.

S: The MT5634ZLX needs 32 contiguous I/O ports

and one interrupt request for its LAN
connection. It also need 8 contiguous I/O ports
and another interrupt request for Fax/Modem.
The LAN ports must be located at one of the
following I/O addresses: 0x300, 0x320, 0x340,
0x360. The Fax/Modem ports must be located
at one of these addresses: 0x2F8, 0x3E8,
0x3E8. (There are also compatibility issues with
certain Fax/Modem software applications.) We
recommend assigning the Modem Interrupt

MT5634ZLX Owner’s Manual

46

(MIR) a value less than 7 (IRQ3 to 6). Make
sure that these resources are available for the
MT5634ZLX.

Enabling The MT5634ZLX
S: If the Card Service is installed, you can check

by hearing the beep when card insertion.

S: Run CARDEN /CHK to check if the

MT5634ZLX has been enabled. The resources
allocated for the card are shown as below at the
last line of the display message.

The NetWare Driver Runs Successfully but Fails
to Login to The NetWare Server

C: The client Frame type is incompatiable with the

server Frame type.

S: The default frame type for Netware 3.11 and

below is 802.3 but it changed to 802.2 in
Netware 4.x and 3.12. Check the content of
NET.CFG to see if the Frame type is acceptable
by the server. If the Frame type can not be
accepted by the server, edit NET.CFG to
change the Frame type at the client site, or add
the Frame type which can be accepted at the
server site.

COM Port and IRQ Conflicts

If you have isolated the problem to an IRQ or COM

Appendix B - AT Commands,

S-Registers & Result Codes

Introduction

This chapter describes how to use MT5634ZLX AT
commands, S-Registers and Result Codes.

How To Use AT Commands

Usually, your fax and data comm software controls
the modem for you. However, you may also want to
use the AT commands. These commands give you
complete control over your modem. You need to be
careful when using these commands, because they
can cause your software to loose its ability to control
the modem. If you do find that an AT command has
caused a problem, then turn the computer off and
then back on. That will reset most AT commands to
the factory default settings. You can also type

AT&F&WZ

to go back to the factory default setting.

To use an AT command, you must first:

1. Run your communication software.

2. Configure the software for the appropriate COM
port and IRQ settings, if necessary.

3. Enter Terminal mode (also “Command mode”,
“Local mode”, or “Direct mode”). This is the
mode in which most data comm software
packages start up. You can then type the
desired AT command, then press the Enter key.

59

Appendices

For example, type:
ATH0<Enter> to hang up the modem connection,

or
AT&K3<Enter> to enable bi-directional CTS/RTS

hardware flow control.

Most of the AT commands can be entered in
“strings” (i.e., on the same command line) without
spaces between the individual commands. For
example:

AT&K3H0<Enter>

As shown above, it is not necessary to put spaces
between the commands. So, there are no spaces
between AT,

&K3

, and H0.

The modem usually returns a response (or “Result
Code”) at the next line if it understands the
command. The response is usually

OK

or

ERROR

unless the AT command provides other (extended)
messages.

S-Registers (ATSn=x)

Certain modem parameters are stored in memory
locations called S-Registers. Use the S command
to read or alter the contents of S-Registers.

S0= 0-255
S0 sets the number of the rings required before the

modem automatically answers a call. Set “S0=0” to
disable auto-answer mode. The factory default
setting is 0.

S1= 0-255
S1counts the incoming rings and stores the value to

this register. The value of this register is
incremented with each ring. If no rings occur over an
8 seconds interval, this register is cleared. User can
read but should not change this value. The factory
default setting is 0.

S2= 0-255
S2 holds the decimal value of the ASCII character

used as the escape character. The default value
(043) corresponds to an ASCII character “+” (plus).
A value of 128 to 255 disables the escape process,
i.e., no escape character will be recognized 043.

S3= 0-127
S3 holds the decimal value of the Carriage Return

<CR> character used as the command line and
result code terminator (asynchronous operation
only). The factory default is 013.

73

Appendices

S4= 0-127
S4 holds the decimal value of the character

recognized as a line feed (asynchronous operation
only). The line feed control character is output after
the carriage return control character, if verbose
result codes are enabled. The factory default is 010.

S5= 0-127
S5 holds the decimal value of the character

recognized as a backspace (asynchronous
operation only). The modem will not recognize the
backspace character if this register is set to a value
greater than 32. The factory default is 008.

S6 = 0-255
S6 sets the length of time, in seconds, that the

modem must wait (minimum 2 seconds even if the
value is less than 2) after going off-hook before
dialing the first digit of the telephone number
The factory default is 002.

S7=1-255 for international version. The factory
default is 060.

S7=0-58for Japan version. The factory default is

058.
Set the time, in seconds, that the modem must wait

before hanging up because carrier is not detected.
S8= 0-255
S8 sets the time, in seconds, that the modem must

pause when the “,” dial modifier is encountered in
the dial string. The factory default is 002.

MT5634ZLX Owner’s Manual

74

S9=1-255
S9 sets the time, in tenths of a second, that the

carrier must be present before the modem considers
it valid and turns on RLSD. The factory default is

006.
S10=1-255
S10 sets the length of time, in tenths of a second,

that the modem waits before hanging up after a loss
of carrier. The factory default is 014.

S11=50-255
S11 sets the DTMF duration and inter digit delay in

mini-seconds, in DTMF touch tone dialing. The
factory default is 095.

S12=0-255
S12 defines the maximum period, in 2-hundredths of

a second, allowed between consecutive
asynchronous escape character “+” (plus) for the
escape sequence to be considered valid. The
factory default is 050.

S18=0-255
S18 sets the length of time, in seconds, that the

modem conducts a test (commanded by “AT&Tn”)
before returning to command mode. If this register
value is zero, the test automatically terminates, the
test progress must be ended by issuing “AT&T0” or
“ATH” commands. The factory default is 000.

S25=0-225
S25 sets the length of time, in hundredths of a

second, that the modem ignores DTR for before
hanging up. The factory default setting is 005.

75

Appendices

S30=0-90
S30 controls the Inactivity timer, which sets the

length of time, in minutes, that the modem counts
when there is no data flow in or out the DTE serial
port. A connection is disengaged when the counter
reaches the preset value. Setting to S30 =0 disables
the inactivity timer. The factory default settings is

000.
S37=Desired DCE speed (line speed). The factory

default settings is 000.

Canadian Limitations Notice
Notice: The ringer equivalence number (REN)

assigned to each terminal device provides an
indication of the maximum number of terminals
allowed to be connected to a telephone interface.
The termination of a interface may consist of any
combination of devices subject only to the
requirement that the sum of the ringer equivalence
numbers of all the devices does not exceed 5.

Notice: The Industry Canada label identifies
certificated equipment. This certification means that
the equipment meets certain telecommunications
network protective, operational and safety
requirements. The Industry Canada does not
guarantee the equipment will operate to the user’s
satisfaction.

Before installing this equipment, users should
ensure that it is permissible to be connected to the
facilities of the local telecommunications company.
The equipment must also be installed using an
acceptable method of connection. The customer
should be aware that compliance with the above
conditions may not prevent degradation of service in
some situations.

Repairs to certified equipment should be made by
an authorized Canadian maintenance facility
designated by the supplier. Any repairs or
alterations made by the user to this equipment, or
equipment malfunctions, may give the
telecommunications company cause to request the
user to disconnect the equipment.

Users should ensure for their own protection that the
electrical ground connections of the power utility,
telephone lines and internal metallic water pipe
system, if present, are connected together. This
precaution may be particularly important in rural
areas.
