5. TROUBLE SHOOTING
This chapter provides information on the most commom problems, the possible causes, and the
solutions.
The modem does not respond to AT commands.
§ Conflict of COMx: port setting with another device.
§ Change the COMx: port of the USB 56K FAX/MODEM to a free port. Be sure to update
your software COMx: port setting as well.
The modem does not execute the command line.
§ Make sure you are typing 'AT' at the beginning of command line.
§ Make sure the modem is not in Data Mode. type +++ if necessary.
§ Make sure your software is set to the same COMx: port as the modem is.
The modem does not give a response after an AT command was executed.
§ The echo and/or responses may be turned off by the ATE0Q1 commands.
§ Use AT&V to check that.
§ Use ATE1Q0 then Enter to change them back.
§ Make sure the modem is in Command Mode rather than in Data Mode when you type the
AT command.
The modem gives an 'ERROR' response after an AT command was executed.
§ Make sure you did not type an invalid command.
§ Make sure your command line is 40 characters or less in length.
The modem goes off-hook and disables the telephone line.
§ The modem may be set to auto-answer mode when it rings.
§ Typing ATS0=0, then Enter at the command line to disable the auto-answer mode.
The modem does not auto-answer the phone.
§ Make sure the software is configured to auto-answer the phone.
§ Type ATS0=n then press Enter. The n stands for the number of rings the modem will
answer on.
The software does not control the modem properly or can not detect the modem.
§ Make sure the software has been set up correctly. Check the initialization and dial strings.
§ Some TSRs (programs that stay in memory after they are loaded) may conflict with the
communications software.
§ Restart your computer without loading any TSRs.
The characters on the screen are doubled.
§ Both the modem and the software have the echo feature turned on at the same time.
§ Turn off the software echo feature off.
§ The remote modem is echoing your typed characters.
§ Type ATE1 then Enter at the command line. Then turn off the software echo feature.
No text appears on the screen when in data mode.
§ The remote modem is not echoing your typed characters.
§ Type ATE0 then press Enter at the command line. Then turn the software echo feature on.
§ Your software may not be set to use Full Duplex or the remote modem may not be set to use
Full Duplex either.
§ C:The remote modem may be waiting for you to type a command before it will reply with
text.
No text appears on the screen when in command mode.
§ If you can't see the characters you are typing, then type ATE1 then press Enter.
The modem does not dial a phone number after you execute the AT dial command.
§ If you are using touch tone dialing on a phone line that requires pulses, then it may not work.
§ Use ATDT in place of ATDP.
When your communications software tells the modem to dial, it does not.
§ Make sure the software dialing prefix is ATDT.
§ Make sure the software and modem are set to the same COMx: port.
§ The modem may not have hung up the phone line since the last call.
§ Change to command mode and type ATH then press Enter.
When dialing another modem, you receive a 'CONNECT' response, but nothing else.
§ The remote modem may be waiting for you to type a command. Or try to press Enter for
logging on to the remote site.
The modem speaker does not make any sound when you're connecting to another modem.
§ The software may have the speaker disabled.
§ Change the setting in your software or use the ATMn command to turn the speaker on.
The modem disconnects (looses the connection) in the middle of use.
§ The remote modem may have locked up.
§ The telephone switch may have disconnected your call.
§ Your software may have turned off the DTR signal.
The modem does not connect with another modem.
§ There may be a problem with the remote modem if you do not hear the high pitched tone
from the remote modem.
Occasionally, the modem gives a burst of errors.
§ The telephone line may be noisy or bad.
§ Hang up the call and try to connect again for getting a better telephone line.
§ If there are other telephones on the same line that your modem is using, someone may have
picked up a telephone on that extension.
§ Your telephone line may have the call waiting feature.
§ Try adding '*70,' to your ATDT dialing command line. If it doesn’t help, ask your telephone
company how to disable it temporarily.
The modem gets errors in transmitted data randomly.
§ Try to use V.42 or MNP1-4 if possible.
§ Connect the modems at a slower baud rate.
After you download a file, it was not stored on your disk drive.
§ If both modems are using MNP or V.42 protocol, then the flow control may not be enabled.
§ Configure your software to use RTS/CTS flow control. That will cause your computer to
pause long enough for the file to be stored to disk.
The text on the screen is not legible.
§ Your software settings may not match the settings on the remote site.
§ 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).
§ 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 re-establish again.
When using V.42bis or MNP5, some features are disabled.
§ 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
§ When using V.42bis or MNP5, you should use a streaming transfer protocol like
Ymodem-G or Zmodem.
§ Configure your software to use hardware flow control (RTS/CTS ON).
When the modem is connecting to another modem, it reports a higher connect baud rate
that it is really using.
§ The modem defaults to report the modem-to-computer baud rate when it responds with
CONNECT.
§ 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
APPENDIX A: AT COMMANDS SET
Basic AT Commands
A/
A
Re-execute Command
The modem repeats the last command line sent by the DTE. Usually used for re-
dialing.
Note: This command should not be terminated by <CR>.
Answer
The modem will go off-hook and attempt to answer an incoming call. Upon
successful completion of handshake, the modem will go on-line in answer mode.
Notes:
If +FCLASS=0 is selected, the modem will enter the connect state after
exchanging carrier with the remote system. If no carrier is detected within the
period specified in S7, the modem hangs up. Any character entered while
connecting will abort the connection process.
If +FCLASS=1, the modem will go off-hook in V21 answer mode. It will generate
the V21 2100 Hz answer tone for 3 +/- 0.5 seconds, and following a delay of 70 ms,
will proceed as if the +FTH=3 command were issued. At any stage up to (but
excluding) the +FTH=3 command state, any character will abort the
communication.
If +FCLASS=8 (#CLS=8), the modem will go off-hook and a voice session will
take place.

Dial
Directs the modem to go on-line, dial according to the string entered, and attempt
to establish a connection.
The Dial String may consist of any of the characters described below:
T Tone dialing (first character in the string)
P Pulse dialing (first character in the string)
L Redial last dialed number (first character in the string)
0-9 Digits 0 to 9.
* Asterisk (tone only)
# Hash (tone only)
W Wait for dial tone; the modem will wait for dial tone before dialing the digits
following “ W”. S6 register will be used for timeout. (X3 or higher)
, (Comma); Pause for the time specified by S8 before resuming the dialing
; (Semicolon) Return to command mode after dialing. This allows the user to
issue additional AT commands while remaining off-hook. Actual call
progress will be entered only after a dial command issued without the “ ;”
terminator.
S=n Dial the number stored in the directory; n=0-3 (see &Z).
! Flash; The modem will go on hook for a time defined by S24.
@ Wait for silence; The modem will wait for at least 5 seconds of silence before
resuming the dialing. If no such silence is detected before the expiration of
the call abort timer (S7), the modem will terminate with NO ANSWER
response (or BUSY if applicable). If answer tone arrives during execution of
this parameter, the modem handshakes. (X3 or higher)
(),< > (space) String format characters - ignored
<i> any other character - ignored.
Notes:
§ If +FCLASS=0 is selected, the modem will attempt to connect with another
data modem. The modem will use the time period specified in S6 and S7 as
time-outs in the handshake process. If a timeout expires, the modem will go
on-hook and respond with NO CARRIER response. The command will be
aborted in progress is a DTE character is entered before completion of the
handshake.
§ If +FCLASS=1, the modem will attempt to connect with a fax machine (or
modem) by entering the HDLC V21 channel 2 receive state (as if +FRH=3
had been issued).
The command will be aborted upon receipt of a DTE character if the modem
has not finished dialing. In this case the modem will go on-hook and return to
command mode responding with NO CARRIER message. If the modem has
finished dialing, It proceeds as if +FRH=3 command has been issued.
§ If +FCLASS=8 (#CLS=8), the modem will go off-hook in V21 answer mode.
It will decide (based on timers) when the other side answers in voice and a
voice session will take place.

AT+MS Command
+MS
Modulation select
This command selects the modulation, optionally enables/disables Automode,
and optionally specifies the lowest and highest connection rates.
The command format is:
AT+MS= [<mod>][,[<automode>][,[<min_rate>][,[<max_rate>]]]]
<mod> a decimal number specifying the preferred modulation (automode
enabled), or the modulation (automode disabled).
<automode> 0/1 Automode disabled/enabled
<min_rate> minimum rate for connection. If lower than the actual minimum rate
for the selected modulation, the actual lowest supported rate will be
taken.
<max_rate>maximum rate for connection. If higher than the actual maximum
rate for the selected modulation, the actual highest supported rate
will be taken.

AT* Commands – Black List Support
Note: The following command will always return OK as a result code.
*B
Return Blacklisted numbers
Blacklisting is a country dependent parameter.
When no time-out is defined:
When a number is unsuccessfully called x successive times, it is blocked
altogether, until next system reset.
Further calls will return BLACKLISTED code.
When time-out is defined:
When a number is unsuccessfully called x successive times, it is blocked
temporarily until the time-out expires.
Calls within the time-out period will return DELAYED code.
Format:
No. Called Blocked Phone
Index # of calls ‘ ‘ (blank) Phone number
- not blocked
(number still candidate for blacklist)
or
‘*’ (asterisk) - blacklisted/blocked
or
‘Xmin’ - # of min to time-out – delayed
Example 1: No time-out defined. Full blocking occurs
