Communication Software
This chapter gives you tips on how to configure your communication
software.
4.1
Installing the Communication Software
The Modem package comes with a Communication software disk and
manual. To install the Communication software,simply insert the
communications software CD into the CD-ROM drive,under
Win9X/ME/NT/2000, the auto-run function will start the shell program,
just follow the instruction on the screen for software installation.
If you want to use other communication program, please refer to section
4.2.
4.2
Tips on Configuring the
Communication Software
This modem uses the most up-to-date industry and commercially
popular standards to ensure functional compatibility with most
communication software. During initial setup of the communication
software, it will normally prompt you to define the type of fax/modem that
you are currently using. The following list guides you on how to select
the proper device type.
The device type only defines the protocol by which
your software will communicate with your fax/modem
and does not set nor limit the speed.
Communication Software
4-1
1.
For the Baud rate, choose any speed between 38,400 to 115,200.
Your fax/modem will automatically adjust to the optimum
transmission speed after successfully connecting with a remote
fax/modem.
2.
Many communication software use the modem response to control
program flow. Make sure that the software is set to recognize a
CONNECT 28800 response. If this does not work, set the program
to simply recognize just the CONNECT response without any baud
rate information.
3.
There are three flow controls: none, hardware (CTS/RTS), and
software (XON/XOFF). Set your software to use either hardware
or software flow control. If set to none, the communication
software will not be able to detect a buffer overflow and result in
transmission errors.
4.
For fax device type, choose TR29 Class 1.
5.
For fax speed, choose automatic or fastest speed. Your
fax/modem will automatically adjust to the optimum transmission
speed after successfully connecting with a remote fax machine or
another fax./modem.
6.
Make sure that you have correctly set all the other parameters
required by the software to operate successfully.
7.
Refer to your Communication software manual for details.
You are now ready to do fax/modem communication. See Chapter
5 for details.

AT Commands
The AT commands are used to directly handle fax/modem data
activities, such as dialing or answering a data call or sending a fax. To
send commands to your modem, you must access the modem in a
terminal mode which is provided by most communication software.
Also, you need to know the format for typing the fax/modem commands
and responses.
This chapter tells you how to properly use the AT commands.
If you will be using a communication software
program to do fax/modem communication, you will
probably not need to type the commands because the
software program will handle these tasks for you.
Similarly, you will not see the response because your
software program may intercept them.
5.1
Entering a Command
To enter a command:
1.
Type AT. This is the Attention Code informing the modem that a
command follows. The Attention Code may be in upper or lower
case.
2.
Type the command. Refer to the succeeding sections.
3.
Press
to send the command to the modem (except for A/ and
+++ commands).
AT Commands
5-1
For example:
ATccpp
where: AT: Attention Code
cc: any command
pp: any parameter that is required by the command
The following sections tell how to enter basic commands. The other
commands are described in the AT_CMD.TXT file contained in the
fax/modem driver diskette. You may use DOS EDIT or any suitable
editor to view this file.
5.2
Repeating a Command (A/)
The A/ command tells the modem to repeat the last command you
entered.
When entering this command, DO NOT type the AT
after
before this command and DO NOT press
entering the command.
5.3
Dialing (D)
The D command dials the phone number. For example, to dial the
number 02-1234-5678, type:
ATD12345678
Then press
5-2
. All three entries are treated the same.
User Manual
You may use numbers 0~9 in all dial strings. You may also use spaces,
hyphens, parentheses, or any other punctuation except the dial
modifiers to make the command line easier to read.
5.4
Tone or Pulse Dialing (T or P)
To tone or pulse dial a number sequence, insert a T or P between the
dial command (D) and the phone number. The modem prepares for
tone dialing.
If you have used P in the last dial string, you only need
to enter a T in the dial string.
For example:
ATDT(or P)12345678
5.5
Pause (,)
Inserting a Pause command in the dial string inserts either a 2-second
pause or the value in status register S8 in the dialing sequence.
For example:
ATDP,12345678
AT Commands
5-3
5.6
Wait for Second Dial Tone (W)
The W command makes the modem pause and listen for a second dial
tone before continuing the dial command.
For example:
ATDW0212345678
You can use the pause and wait for second dial tone commands when
using long distance services.
5.7
Call Transfer or Other On Hook Feature
(!)
Enter an exclamation mark (!) to transfer a call or do something similar
that requires on-hook or ″flash-hook”.
For example:
ATDT9,323-8000!,#7377
5.8
Wait for Silence (@)
The Wait for Silence command is used for special service like automatic
paging. The @ modifier tells the modem to wait for one or more rings
then listen for 5 seconds for continuous silence before dialing. If 5
seconds of silence is not detected within the time set in register S7, the
modem hangs up.
5-4
User Manual
5.9
Storing Telephone Numbers (&Zn=t)
The modem can store up to four sets of telephone numbers; each set
dial string can contain up to 34 digits. To store telephone numbers
including all the dial modifiers that you may need, enter:
AT&Zn=t
where: n = locations 0~3
t = 0~9, *, # and any of the dial modifiers T, P, W, @, ;, !.
For example, to store the dial sequence T9,1551212 at location 2, type:
AT&Z2=T9,1551212

Dialing Stored Numbers (S=n)
Enter ATDS=n to dial the phone number stored at location n (where
n=0~3).
5.11
Answering a Call
5.11.1
Manual Answering (A)
The factory presets the modem to answer a call only when you enter
ATA. This is useful especially if you are using only one telephone line
for your modem and telephone.
AT Commands
5-5
5.11.2
Auto-answering (S0=n)
The modem default setting is not to answer a call unless you manually
enter the ATA command. However, if you have a separate telephone
line for the modem and your telephone, you can set the modem to
automatically enter incoming calls.
You can specify the number of rings before the modem answers the
call. To specify, type:
ATS0=n
where: n: is the number of rings after which, the modem answers the
call. The settings are from 1~255. Set S0=0 to disable auto-answer
(default setting).
5.12
Hanging Up or Going Off Hook (H)
Enter:
5-6
ATH
to let the modem hang up.
ATH1
to let the modem go off-hook
User Manual
5.13
Selecting Response Message (Vn)
The V commands tell the modem to show response messages as
words or numbers. See Table 5-7 for the list of response messages in
both numbers and words.
Enter:
V0
Enables number response message.
V1
Enables word response message.
5.14 Enabling/Disabling the Speaker (Mn)
This command lets you enable or disable the speaker.
Enter:
Speaker always off
Speaker on until carrier present ( default )
Speaker always on
Speaker off during dialing ; speaker on until carrier
Present

5.16
Reading an S-Register Value(Sn)
To read the current value of an S-Register, type:
ATSn?
where n is an S-Register number. The modem responds with decimal
value of the S-Register, in three-digit format followed by OK.
To read values from more than one S-Register, type:
ATSn?Sn?
where n specify the different S-Register numbers.
5.17
Changing an S-Register Value (Sn=x)
To change an S-Register value, type:
ATSn=x
where: n: S-Register number
x: value you want to assign to the specified S-Register

5.18
Sending Faxes
You can send a fax using the fax software. The commands are
automatically issued by the fax software. In case you encounter some
problems while sending or receiving a fax, refer to your fax software
manual.
Some fax packages require software flow control.
The modem uses the hardware flow control as the
factory default. You may need to enable the software
flow control to send and receive faxes.
5.19
Checking Data or Fax Status
(+FCLASS=?)
This command identifies if the modem is set for data or fax operation.
The possible values are 0 for data mode and 1 for fax class 1.
