Section 3. Commands
Most people use the communication software programs to tell modem what
they want the modem to do.Therefore, you may not use the commands in this
chapter. However, if you prefer to communicate with your modem more
directly, you can type the following commands. Please note that when your
typing appears on the screen, your modem is in a "terminal mode". this
chapter will be helpful if you like to work in a terminal mode.
3.1 Note When Typing Commands
þ Use the BACKSPACE key to delete typing errors.
þ Every command (except A/ and +++) must begin with the AT or at prefix
and be entered by pressing the ENTER key. For example, to execute the V
command, you would type ATV and press the ENTER key.
þ When you see an n, replace the n with one of the letter or numeric
options listed for that command. For example, for the En command, you
might type ATE1.
þ If a command has numeric options and you don't include an number, zero
is assumed. For example, if you type ATB to indicate a Bn command to be
ATB0.
þ All defaults are based on the &F Hardware Flow Control template load in
NVRAM when the modem is shipped.

3.4 Using AudioSpan/DSVD Function
AudioSpan and DSVD are two technologies that allow simultaneous voice and
data operation using a Rockwell modem connected to a telephone line.
AudioSpan and DSVD implementations differ in the manner that voice and
modem data are combined. Voice and data channels are combined in the analog
domain for AudioSpan and in the digital domain for DSVD.
A handset, headset, or microphone/speaker can be used for voice
communication during AudioSpan or DSVD.
NOTE: The DTE rate must be equal to or greater than the anticipated DCE
connection speed. In general, DTE speed of 38400 bps or higher should be
used.

Section 4. Appendix
4.1 Troubleshooting
If you experience a problem with your fax/modem, refer to this appendix
for suggestions on resolving the problem.
1. Why internal modem ( Without PnP ) can't install successfully in
Win95 ?
þ Please check "Control Panel"__"System"__"Device Manager"__"COM &
LPT" item. Did the COM port for your modem's setting have been
opened? If no! Goto the "Control Panel"__"Add New Hardware"__click
"Next Step"__click "NO"__ click "Next Step"__then in "COM & LPT"
icon, choice communication port, open the COM port for your modem.
2. If your modem doesn't respond to any AT commands.
þ Make sure the modem is on. (externals only)
þ Make sure you selected the correct COM port and IRQ in your
communications software, and /or in your windows Control Panel.
þ Make sure the computer is in Terminal mode of your communications
software.
þ Type in all upper (AT) or lower (at) case.
þ There may be a COM port/IRQ conflict. Refer back to Internal
Installation. You will need to remove your modem from the PC and
change your COM port and IRQ setting to COM port 3 and IRQ 5 or 7.
If you change your COM port and IRQ setting, also make the changes
in your software and in Windows.
3. Type a command line and receive an ERROR result code.
þ You typed an unacceptable command.
þ Your command line contains more than 40 characters.
4. Do not receive a result code after your fax/modem executes a command
line.
þ All fax/modem result codes may have been disabled with the ATQ1
command. Send the ATQ0 command to enable result codes.
5. Your fax/modem responds to commands but your computer screen doesn't
show the characters you type.
þ Make sure the command echo is off (ATE1 in effect) to have your
fax/modem echo commands.
þ Make sure your communications program is configured to echo command
characters.
6. Each character you type appears twice on your computer screen.
þ Your computer or communications software has its echo feature is
also turned on. If the system you are calling echoes your typed
characters, turn off local echo at your computer, terminal, or
computer software. If the system you are calling doesn't echo type
characters, turn off the fax/modem's echo feature by typing ATE0
(which appears as AATT EE00 on your screen) and pressing the Enter
key.
7. Your fax/modem does not automatically answer calls.
þ Make sure your communications software is set up to automatically
answer calls.
þ Change the value of Register S0 by typing AT S0=n and pressing the
Enter key, where n is the number of rings that must occur before the
fax/modem auto-answer calls.
8. You can't hear through your fax/modem speaker.
þ Use the ATMn command to make sure the speaker is turned on.
þ Use the ATLn command to adjust the listening level.
During data transfer
9. If your screen display random or garbage characters.
þ Set your software to the same word length, parity, and Stop bits as
the remote modem.
þ Make sure that your software and modem are set to the same flow
control setting and to either a fixed or variable serial port rate.
þ Type the following command to load the template that enable hardware
flow control as well as other optimal settings.
AT&F <Enter>
þ Disable any Terminate and Stay Resident (TSR) programs running in
the background.
10. If your communications software is reporting many Cyclic Redundancy
check (CRC) error and low characters per second (CPS).
þ You might have experienced noise on the phone line. Place the call
again. The phone company routes calls differently each time your
call.
þ Type the following command to load the template that enables
hardware flow control as well as other optimal settings:
AT&F <enter>
þ Lower the serial port rate in your communications software to 38400
bps or 19200 bps.
þ Try a different file transfer protocol (do not use Xmodem if other
protocols are variable).
þ Disable any Terminate and Stay Resident (TSR) programs running in
the background, such as screen savers.
11. If the modem disconnect while on-line.
þ Check for loose connections between the standalone modem and the
computer.
þ Check for loose connections between the modem and the telephone
connections.
þ Line noise or interference may be interfering with modem signals.
Retry the connection by dialing the number again.
4.2 What is K56flex (X2) ?
K56flex (X2) is a new modem technology that enable Internet connect at
blistering rates up to 56 Kbps over standard telephone lines. Bridging the
gap between current analog transmission rates and fully digital
communication -such as Integrated Services Digital Network (ISDN)- this
new technology offers substantially faster speeds without requiring the
added investment of installing digital ISDN lines.
This means that graphics-heavy Web pages, sound and video files-the
information that usually makes you wait - now race to your computer at
nearly twice the speed of current V.34 connects. Only if K56flex (X2)
modem connected to an Internet Service Provider (ISP) or corporate site
using K56flex (X2) technology over their digital connection to the
network, you can realize the increase in speed.
Download Driver Pack
After your driver has been downloaded, follow these simple steps to install it.
Expand the archive file (if the download file is in zip or rar format).
If the expanded file has an .exe extension, double click it and follow the installation instructions.
Otherwise, open Device Manager by right-clicking the Start menu and selecting Device Manager.
Find the device and model you want to update in the device list.
Double-click on it to open the Properties dialog box.
From the Properties dialog box, select the Driver tab.
Click the Update Driver button, then follow the instructions.
Very important: You must reboot your system to ensure that any driver updates have taken effect.
