The +MS=m command specifies the allowable connection modulatios
and data rates. The +MS=m command uses four parameters: <carrier>,
<automode>, <min rate> and <max rate>.
It is important to remember that the ordering of commands is important
in configuring the modem. For example, if the DTE 9600 bps data rate
and the AT commands are issued in the following sequence, different
connection rates result:

 1.    ATS37=0                    2.     AT+MS= V32B, 1, 0, 14400
       AT+MS=V32B, 1, 0, 14400           ATS37=0

NOTE: This verbose response code is used to evaluate the modem connection
      and is enabled by the W3 AT command. All other 'CONNECT' messages
      are used for W0-W2 AT commands.
When the modem is configured for text responses V1, the W3 verbose
response codes provide information about the DTE data rate, connection
modulation, error correction protocol, data compression, and modem-to-
modem data rate. When the modem is configured for W3 and numeric responses
V0, the modem responds as if it were set up for W0.

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
    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
    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

 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

 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
    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
    þ Check for loose connections between the modem and the telephone
    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.
