Chapter 3 Using configuration profiles
Your modem is preset so that you can begin transferring data files as soon as you install
the modem and lead your communication software.
it you dialing and answering requirements do not match the modem's default configuration
profile, you can create your own profiles and store them safely in your modem‘s nonvolatile
memory. The profiles will be saved, even when you turn off your modem. When you need
to use a certain profile, send the appropriate command.
You can save two custom configuration profiles in your modem's nonvolatile memory You
save profiles using &Wn command, The n can be the number 0 or 1, which corresponds to
the location in nonvolatile memory where you want the profile stored.
Using the &Wn command, you can store the following commands (refer to Chapter 5 for
description of these commands).
81, T, E1, F0, L2, M1, Q0, V1, X4, Y0, 8-00, &D0, &G0, S-JO, &K3, &LO, &P0, \A3, \BZ,
%C1, \N3 .........
You can also store the following register values (refer to Chapter 6 for a description of
these registers) :
80:0, 52=43, SG=2, S7=30, SB=2, 59=6, 510=14, S11=95, S12=50, S18=0, $25=5
3.1 Storing a profile
The followtng example shows how you can store a profile. Assume that you want to save
the following commands in profile 0‘
X1 E0 8-01 8.00 &M0 30:3
Todo so:
1 Type AT
2. Type the commands shown above
3. Type the &WD command as the last command on the command line to save these
commands as user Profile 0.
4. Press the Enter key. This custom configuration profile is now saved under user Profile
0.
3.2 Recalling a profile
After you store a custom configuration profile, you can recall it using the AT&Yn command.
For example, to recall profile 0'
Type ATE-YO
1 Press the Enter key The next time you turn on or reset your modem, it will drive its op-
erating characteristics from Profile 0
_—“——————_
17
5634IF User’s Manual
2. To recall Profile 1 instead of Profile 0, type AT&Y1 instead of AT&Y0.
3.3 Reset and recalling profile
If you prefer, you can use ATZn command to reset the modem and load a stored configu-
ration profile : For example. to reset your modem and recall Profile 0 :
1, Type ATZO
2. Press the Enter key.
Returning to the default profile
1 To return to the factory default profile 0:
2. Type AT&F0
Press the Enter key. Your modem returns to basic asynchronous operation, which is the
profile in effect when you received your modem. The following table lists the modem’s de-
fault profile. ~

Chapter 4 Error correction and data compressron
Your modern supports sophisticated MNP 1- 4 and v.42 error— correcting protocols These
protocols ensure the transmission of errcr~free data — even over noisy, error— prone tele-
phone lines. Your modem also supports the v.42bis and MNP 5 data-contoression proto-
cols, which maximizes data throughput and significantly reduces the time needed to ex-
change data.
4.1 Error-correction protocols
Your modem includes two error-correction protocols:
. MNP level 1 through 4
- CCITT v.42
When these protocols are used, the two modems perform calculations on each ”packet" of
data being exchanged and compare their values. If the values do not match, the receiving
modem requests the sending modem to re transmit the packet.
MNP is an acronym for Microcom Networking Protocol. MNP detects and corrects errors
that occur when data is exchanged between two systems. Errors can result from tele-
phone line noise and other signal distortions.
4.2 v.42
v.42bis the accepted international standard for error correction, ratified by ITU-T in Janu-
ary 1990, it is generally felt that the handshake and protocol establishment process of
v.42 is superior to that MNP 4 Therefore, it will provide better initial connections on poor
quality telephone lines,
Moreover, while the effective data speed of v.42 and MNP 4 are almost identical over
noise—free telephone lines, V 42 provides significantly better performance than the ITU-T—
specified MNP4 over n0isy telephone lines.
4.3 Configuring for auto-reliable operation
Auto-reliable operation is the modem's default configuration, so if you haven‘t given the
modem any \N commands, it should already be in auto-reliable mode.
Auto-reliable mode lets your modem communicate with both MNPN.42N.42bis modems
and modems that do not use MNPN.42N.42bis:
1. Type AT\N3%C3 (Factory Setting)
2. Press the Enter key. Your modem responds With OK, When your modem originates or
answers calls. it will try to make a V.42bisN.42 connection. it either or both fall, your
modem will try to make an MNP connection, If that fails, your modem will try to make a
normal connection that does not use error correction,
19
5634lF User’s Manual
4.4 Configuring for reliable operation
To communicate with remote MNP modems only:
1. Type AT\N5
2. Press the Enter key, Your modem responds With OK. When your modem originates or
answers calls it will try to make an MNP connection. If that fails, your modem will hang
up and return to command mode.
To communicate with remote v.42 modems only:
1. Type AT\N4
2. Press the Enter key. Your modem responds with OK. When your modem originates or
answers calls, it will try to make a V.42N.42bis connection. if that fails, your modem
will hang up and return to command mode \
4.5 Turning off error-correction
To turn off the MNPN 42 error correction and communicate with non-MNPN/lz modems:
1. Type AT\NO and press the Enter key to return to standard operation with buffering. or
AT\N1 and press the Enter key to return to standard operation without buffering
2. Your modern responds with OK.
4.6 MNP5 and v.42bis data-compression
There are two major data-compreSSion protocols used in data communications, MNP5 and
v.42bis. MNP5 was the first data-compression protocol to be developed and provides a
data—compressmn ratio of 2-1
In January 1990, lTU-T ratified the v.42bis datacompression protocol as the international
standard. v.42bis performs Significantly better than MNP5, providing a dataacompression
ratio of approximately 3:1 — and in some case, up to 4:1.
By supporting both types of data-compression protocols, your modem can communicate
With the installed base of MNP5 and V 42bls modems and modems.
To communicate with remote MNP5 modems only
1. Type AT%C1
2. Press the Enter key. Your modem responds With OK. When your modem originates or
answers calls, it Will try to make an MNP5 connection, If that falls, your modem will
hang up and return to command mode.
To turn off v.42bis and MNP5 data compression:
1. Type AT%C0 ; Press the Enter key. Your modem responds with OK.

Chapter 5 List of modem commands
Chapter 5 describes the modem commands available to your modem. If you Wll| be using a
data communication software program to send and receive files you will probably not
need to use these commands, because your software program ml handle these tasks for
you) However, if you want to bypass your communication software program and perform
modem tasks directly with your modem, you will find the commands described in this
chapter helpful.
Standard modem commands begin at Table 5-14 MNPN.42N.42bis commands begin on
page 38. If a command requires parameters such as G and 1, the parameter is identified
as n in the left column and described in the right column in the following tables.
— Remember that each command, except for +++ and Al, is prefaced by AT and ex-
ecuted when you press the Enter key. To review the format used to send modem
commands, refer to Chapter 2.
Please refer to Chapter 4 for more information on MNPN.42N.42bis error correction and
data compression protocols,

Commands ‘ a , , ,
+ ++ Keep data connection and move from data mode to command
mode
When your modem enters the data mode, typing +++ allows it to as
cape to the command mode while preserving the connection to remote
modern.
A Answer command
Force the modem to go off-hook in answer mode without waiting for a
ring. Use this command to manually answer an incoming call.
AI Re-execute last command
Repeat the last command line it executed. Not preceded with AT nor
followed by pressing the Enter key. This command is useful when you
want the modem to redial a telephone number that was busy. The last
command line executed stays in the modem‘s memory until power is
turned off or the modem is reset. Either action invalidates the A/ com-
mand, because there is no command in memory to execute,

Chapter 6 List of modem S-register
Your modem has S-registers that affect various operating characteristics, let you obtain
information about the modem. and let you test the modem. Each S—Register has a factory-
set value, which you can read or change to fit your particular requirements. Chapter 6 ex—
plains how to read and change S-Register repeatedly, A sequential list of S—Register is
also provided,
6.1 Reading an S-Register value
To read the current value of an S-Register:
1. Type ATSr? from the command mode, where r is an S—Register number.
2. ~ Press the Enter key. The modem responds with decimal value of the S-Register , in
three-digit form. followed by OK.
To read values from more than one S-Register :
1. Type ATSr?Sr? from the command mode and press the Enter key. For example, to
read the value of Register SO (auto-answer after the number of rings specified by this
SvRegister value) and S1(count the number of incoming rings), type ATSO?S1? from
the command mode.
2. Press the Enter key The modern displays the first S-Register value, a carriage return,
the next S- Register value, a carriage return, and OK(or 0).
6.2 Changing an S-Register value
To change an S-Reglster value, use the Sr=n command, where r is an S-Register number
and n is the new value you want to assign to the S-Register. For example, to have the mo—
dem auto-answer incoming calls after the third ring:
Type ATSO=3 from the command mode,
1. Press the Enter key. The modem responds With OK or 0 to show it has executed your
command and changed the S»Register value. The value remains in effect until the mo-
dem is turned off and on, or reset. The modem then revert to its default S»Reg‘ister
values (in this case, Register SO returns to a value of 0, disabling auto answer).
6.3 S-Register descriptions
Table 6-1 summarizes the modem S»Register, their default values, and theirfunctions.

Table 6-1 S-Register description
S-Register Range 4 Default Description
SO 0-255 rings 0 Auto-answer
Assigning a value from 1 to 255 in Register 80
tells the modem how many rings must occur
before it can auto—answers calls. The default, 0,
turns off the auto-answer feature.
81 0-255 rings 0 Count incoming rings
Register 81 counts the number of incoming
rings when your telephone line rings. When this
value equals the value in Register $0, the mo—
dem auto—answer calls. This S-Register resets
approximately 8 seconds after the last ring.
32 O»255. 43 Escape character value
ASCII (+) Register 52 sets the ASCII value of escape
characters. that swnch the modem from data
mode to command mode without losing the con—
nection to the remote modem, Values greater
than 127 disable the escape feature, preventing
a return to the command mode. To return to
command mode with the escape characters dis-
abled, the remote modern must hang up or an
ON-to-OFF transition of the DTR interface signal
must occur with 8-D1, $02 or aos in effect.
83 0-127, 13 Carriage return character
ASCII (Carriage Register 53 sets the ASCII value of the carriage
Return) return (end—of—Iine) character, This is the char-
acter used to end the command Iine(and have
the modem execute the line) and also the char—
acter that follows modem responses.

Feed) 'character. The modern sends this character af»
ter a carriage return only when word responses
are sent (V1 command in effect). If a line feed

ASCII (Back- Register 85 sets the ASCII value of the back-
space) space character is the one created by passing
the Backspace key and the character echoed to
move the cursor to the left, To change this
value, assrgn an ASCII value between D and 32
or greater than 127. Do not use values between

4-255 sec- Dial tone wait time
onds Register 86 determines how long the modem
waits before dialing the first digit in Dial com-
mand line. This feature is convenient when it
takes longer than two seconds to obtain a dial
tone.
1-255 sec- Carrier wait time
onds Register 57 tells the modem how many seconds
to wait for a remote modem's carrier signal be-
fore hanging up, The S7 value can be increased
if the modem does not detect a carrier within the
specified time. If the modem detects a remote
carrier signal within the specified time, it sends a
CONNECT response and enter data model if it
does not detect a remote carrier within the
specified time, it sends N0 CARRIER , hangs
up, and remains in command mode,
0—255 sec— Comma pause time for dial delay
onds Register SS tells the modem how many seconds
to pause for each comma (,) in a Dial command
line. The comma is used when dialing through a
PBX or other special telephone service to wait
for an outside telephone line.
1-255 Carrier detect response time
tenths Reglster SQ tells the modem how long the re-
of a sec- mote modem's carrier signal must be present so
and the modem does not mistake the signal for a
busy signal, ring, or voice. The default setting
requires the modem to the carrier signal for at
least 046 seconds before recognizing it. In-
,creasing the time in this S-Register reduces the
chances that the modem will mistake noise such
as a busy signal or voice foe carrier signal,
1-255 Carrier loss time
tenths Register S10 sets the time between the loss of a
die sec- remote modem‘s carrier signal and when the
and modem disconnects This allows the remote
modem's carrier signal to momentarily disappear
from the telephone line without the modern dis—
connecting.
Touch-Tone speed
Register 811 controls the speed of the Touch—
Tone (DTMF) dialing, Increasing this value to
255 slows the dialing rate to 19 digits per sec-
ond Do not select a value less than 50 millisec-
onds. (Register 811 does not effect pulse dial-
ing, which is fixed at 10 pulses per second.)

Escape character guard time
Register 812 controls the time delay required
before and after typing the escape characters.
The default setting, 50, equals one second. To
reduce the chance that transmitted data is mis—
taken for escape characters, the S12 value can
be increased, but this makes using the escape
characters time-consuming. If a small value is
used, it may be hard to type the three escape
characters fast enough, especially if the guard
time is less than the time needed to send 1
character at the current transmission speed. If
S12=O , there will be no time requirement for
typing escape characters,

Chapter 7 Hardware Quick Installation Guide
Before you begin installing your modem. ru‘ re followmg tests first:
isentiry an available COM port address and lRQ (interrupt) for your modem.
Do you have either a sound card, a network card, a scanner card, or a bus mouse? If
you do so, find out their IRQ settings from your computer dealer or from the hardware
manuals.
7.1 FOR WINDOWS 95
I Add a COM Port
1. Please choose START then Settings, then Control Panel. In Control Panel, double
click on Add New Hardware. In the ”Add New Hardware Wizard" Click on "Next
>" button it will then ask you if you want Windows 95 to search for New Hardware,
click on YES, and then the "Next >" button. Read the Warning, and if you agree, click
on “Next >". Now wait for the Wizard to complete its inspection of your system con-
figuration. You can click on “Details" and if all is correct, then click on "Finish” button.
Then when it asks, click on "Yes" to reboot your computer.
2. Now go to START, then SETTINGS, then Control Panel. Double Click on System.
Then click on the Device Manager TAB Double Click on "Ports (COM & LPT)”.
Whatever COM ports show up, you cannot use for the modem, unless you disable
them first in the BIOS of you COMPUTER, ON the Motherboard or on your l/O Card,
If you choose to disable one of your current ports to put the modem in, then rerun this
test to make sure that it was actually disabled correctly
3. You can now continue to OPTION 1 of this section.
I 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 iden-
tifying 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,
"OSFB" is COM1, "OZFS" is COM2, "03EB" is COMS, and "02E8" ls COM4. If it has
”02E8" under COMS, 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.

5634IF User’s Manual
OPTION _1_
If you only have ”O3F8” in the COM Port screen and do not have any sound card, network
adapter sca. ii ,r card, bus mouse, or other device using lRQa, set your modem‘s switches
or jumpers tc COM2 IRQ3 according to the user's manual that Games with your modem
(both COM and IRQ must be set). If you only have “02F8” for COM port, set your modem
to COM1 lRQA, again followmg 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 IRQS, set your modem to COM3 IRQfi.
OPTION 3
if you have "03F8“ and also have "02E8" and you do not have any sound, network, scan-
ner card, bus mouse, or other devices using lRQS, set your modem to COM2 IRQS.
OPTION 4
If you have "03F8" and also have ”02E8" and you do have another device using IRQS,
please consult your ”Multi I/O Card User‘s Manual" and have COM4 "O2E8" IR03 disabled.
This "Multi l/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 IRQS is disabled on the I/O card.
OPTION 5
If you have both "OSFB" and ”02F8“ and you do have another device using IRQS while you
don't have any external device connected to COM2 "02F8“, have COM2 "02F8" lRQS on
your I/O card disabled. Set your modem to COM2 IRQS after COM2 IRQS has been dis-
abled on your l/O card,
OPTION 6 (depends on your system's multi-l/O card)
If you have both "O3F8" and "O2FB" and do have another devrce using IRQS while there is
an external deVice connected to COM2 "02F8" and a serial mouse is connected to COM1
”0st," you can try to put your modem on COM4 lRQS. However, this is not always
guaranteed to work. it is our experience that whether or not this kind of setting works or
not depends a lot on the multi—I/O card itself, Sometimes the I/O card does not like to
share lRQ (IR03 in this case) with another device, Sometimes this setting will work for a
while and suddenly stopped working. Sometimes it will work flawlessly, The PC Bus
architecture was not designed to share IRQ's.
OPTION 7
if you have a setting that matches Option 6 above and Option 6 does not work on your
system, you can try to move the device that's using lRQS to an unused IRQ and set your
modem to COM3 lRQS If the device that's usrng IRQS does not support other IRQ's, you
have ran out of available IRQ Consult your local dealer or a consultant to see if they can
give you some advice You must also realize that if your system is fully loaded with no
44
5634IF User‘s Manual
available COM 50d or IRQ, another dewce must be sacrificed (disabled) to make room for
the fax modem
When you find :he COM Port and IRQ setting for your modem, set the modem according
to the instructions in your Fax Modem User‘s manual. Turn your computer off‘ unplug the
power cord, remowe the cover to your computer, locate an available expansion slot on the
motherboard, remove the screw that“ holding the slot cover if there is one. and carefully
slide the modem into the slot completely. Secure the modem in the slot with the screw,
Connect your DEDICATED phone wire to the fax/modem's "LINE" jack. You may want to
install the software that came with the package and test the modern before you put the
computer cover back. But be careful not to touch any system components with the power
cord plugged into the wall socket.
NOTE: Windows 3.1x Systems (COM Port Packing)
If you are skipping COM3, and you are installing any Windows based communications
software, you will need to add the following two lines to your SYSTEMilNI file's [386Enh]
section:
Example: COM3IRQ=~1
COM38ASE=03E8
This applies in general to any skipped COM Port‘ where "x‘ is the Port Number skipped
