Release Note on Elite 2864 Version 1.11      Jan. 26, 1996



 1. Improved the V.34 performance.
 ---------------------------------

 2. Fixed modem bugs:
 --------------------
    1) The "carrier lost 1" problem:
       When the modem is connected to a Rockwell chipset based modem on some
       long distance calls, the modem will drop the line immediately with
       disconnect reason shown "carrier lost 1".
    2) Incorrect LED indication:
       The V34 LED does not turn on if "AT&N62" to "AT&N72" command is
       entered. The "V32b" LED will turn off if a V.32 connection is
       established with "AT&N4" command.
    3) Can not connect on two wire leased line mode:
       If "AT&L1" command is entered, the modem will go on-hook and report
       "NO CARRIER" immediately after connection.
    4) Wrong leased line operation:
       If "AT&L1" command is entered, modem will go to handshaking procedure
       immediately.
    5) Incorrect response for numeric form result code (ATV0):
       If "AT&K0&N14V0" command is entered, modem reports connect message as
       "10" instead of "10<CR>" after connection.
    6) Unable to use V.25bis command set.
    7) Sometimes in data state, the modem does not disconnect when DTE drops
       the DTR signal.
    8) Impoved the reliability of recognizing the dial tone, busy tone and
       ring signal in Italy.

 3. Fixed fax bugs:
 ------------------
    1) Incorrect response:
       Modem reports "+FHNG:70" followed by "NO CARRIER" while the incoming
       call is a voice call.
    2) Some compatibility problems of class 1 commands with Win95.
       now the modem responses to the AT+FCLASS=? inquiry with the string
       "0,1,2,2.0,6,8,Z"

 4. Fixed voice bugs:
 --------------------
    1) Fix the problem of BUSY tone detection of Italy:
       In Italy, the modem does not recognize the busy tone in voice mode.
       After recording a message, the modem does not go on-hook and
       continue to record the busy signal.
    2) Improved the VCON reliability.

 5. Added new features:
 ----------------------
    1) Some new user friendly commands:
       ? or $    Basic command summary help.
       &? or &$  Extended AT& command summary help.
       *? or *$  Extended AT* command summary help.
       #? or #$  Extended AT# command summary help.
       +? or #$  Extended AT+ command summary help.
       S? or S$  Show complete register list
       Sxxx=?    Show the function of Sxxx register.
       Sxxx=$    Show the function of Sxxx register.

    2) Multi language support:
       Right now, only two languages are implemented.
       If the value of S63 equals 1, the summary help is displayed in
       German.
       If the value of S63 equals 0, or any value other than 1, the
       summary help is displayed in English.

       [Note]
       . Right now, not all the information pages are available in both
         languages. So the help display is 'a bit' mixed sometimes. But
         this will be filled up with the correct language as soon as
         possible.

    3) Report "DATA or FAX" before showing connect message:
       If bit7 of register S57 is set (default is reset), an additional
       connect message will be displayed on the screen. The additional
       message is "DATA" or "FAX" for data or fax connection respectively.
       For example,
                        AT+FCLASS=1
                        AT+FAA=1

         example 1:     DATA
                        CONNECT 115200/V34  28800/V42b/SREJ

         example 2:     FAX
                        CONNECT

    4) The capability of fax receiving in class 6 is configurable.

          Release Note on Elite 2864 Version 1.10     Dec. 22, 1995



 1. Fixed modem bugs:
 --------------------
    1) Improper remote configuration:
       The local modem can not read or write the remote modem's profile on
       connection.
       (Note: Remote configuration is not inter-operable between an Elite
       2864 and a U-1496 series modem. The Elite 2864 has more S-registers
       and some S-registers have different meaning.)
    2) AT&T6 (initiate remote digital loopback) does not work.
    3) Fail to recognize the dial tone of some PABXs:
       During dialing, the modem reports "NO DIALTONE" when the dial tone
       is not a continuous signal (with ON/OFF cadence).
    4) Incorrect LED indication of dialing, handshaking and retrain:
       The V32b LED does not flash on and off for 1/2 second each to indicate
       that the modem is dialing. Neither do the V34 and V32b LEDs flash
       on and off for 1/2 second each to indicate that the modem is in
       handshaking or retrain.
    5) "ATM3" does not work:
       With the "ATM3" command, the dialing tone is still heard from speaker.
    6) Type 1 security function does not work (the *G1 and *G2 commands).
    7) Does not support up to 50 passwords in security function:
       For example, in *G4 setting, the modem is not able to detect any
       password at location from #10 to #49.
    8) Unable to recognize ring signal on some bad local loop lines.
    9) Incorrect repeat dialing function:
       When bit0 of S38 is set, the modem will not dial the same number again
       while the modem reports "BUSY" after dialing.
   10) Incorrect cyclic dialing:
       When bit3 of S44 is set, the modem will not dial the second number
       while the modem reports "BUSY" after dialing.

 2. Fixed fax bug:
 -----------------
    1) Incorrect LED indicator:
       When "AT+FCLASS=6" command is entered, the V34 LED turns off in
       multi-auto mode (AT&N0).

 3. Fixed voice bug:
 -------------------
    1) Sometimes the modem hangs after issuing <DLE><ETX> to finish playing
       voice.

 4. Add new features:
 --------------------
    1) Set the dial back timer S64 for security call back function:
       (default=0, in seconds)
       With level 2 security, the answer modem will disconnect the line if
       the password has been found in its pre-stored acceptable list.
       The answer modem will dial back the phone number corresponding to the
       dial-in password, when the dial back timer (containded in S64) is
       reached.
       If the content of S64 violates the PTT regulation, the dial back timer
       will be automatically set to the value defined in PTT regulation.
       S64 can be used to control the dial-back waiting time to avoid dialing
       back too quickly that the calling modem's line is still busy.



=============================================================================



             Release Note on Elite 2864 Version 1.09     Dec. 8, 1995


 1. Fixed modem bugs:
 --------------------
    1) Fail to recognize the Italian dial tone.
    2) Failure in dial tone monitoring:
       When "ATH1" command is entered, the modem goes offhook but there is no
       dial tone coming from the modem's internal speaker.
    3) Incorrect response for numeric form result code (ATV0):
       For example, when "AT+FCLASS?" command is entered, modem responds with
       "0<CR>0<CR>" instead of "0<CR><LF>0<CR>" in numeric form.
    4) Problem on forcing V.22bis retrain:
       In V.22bis escape state, when "ATO1" command is entered to force the
       modem to request a retrain, the connect message shows "V.32 9600T".
       And sometimes the retrain fails.

 2. Fixed fax bugs:
 ------------------
    1) Problem on fax reception:
       Sometimes the top portion (the first half inch) of the received page
       is chopped off when the receiving speed is 14400bps.
    2) The AT+FZF=1 setting is not saved with AT&W command.

 3. Add new fax feature:
 -----------------------
    1) The local ID string (AT+FLI=) can be saved to EEPROM with AT&W
       command.

 4. Add new voice features:
 --------------------------
    1) Some programmers need the feature to enable the speaker when recording
       from telephone line. In this version, we let users use VLS=18 (16+2,
       speaker and Telco Line) to enable the speaker.
    2) Some programmers also report that the transmit level of Tone (+VTS)
       and Voice (+VTX) are different. In this version, we let users set
       the transmit gain separately, AT+VGT for Voice and AT+VGN for Tone.
       The default value of AT+VGT is 128. The default value of AT+VGN is
       60.
    3) In this version, users can use s60 bit 4 to disable the Telco line
       playback AGC.

 5. Important notes for voice programmers:
 ----------------------------------------
    From version 1.07, the Near Echo Cancellation is disabled as the default
    setting, this decreases the sensitivity and reliablity of DTMF detection
    when playing voice message. Set the s60 bit 7 will enable the NEC !



=============================================================================



             Release Note on Elite 2864 Version 1.08     Nov 27, 1995


 1. Improved V.34 performance:
 -----------------------------
    1) Solve the "carrier lost 1" problem:
       When connected with a modem employing Rockwell's chipset, after about
       10 minutes of connection, the modem will drop the line with disconnect
       reason shown "carrier lost 1".

 2. Fixed modem bugs:
 --------------------
    1) Cannot report "BUSY" while waiting for the first and second dial tone:
       If bit6 of S57 is set, the modem will report "BUSY".
       If bit6 of S57 is reset (default), the modem will report "NO DIALTONE"
    2) Problem with V.23 mode connection:
       The modem will hang-up within 5-6 seconds of V.23 mode connection.
    3) Wrong change of S-register:
       When "AF+FCLASS=0" command is entered, the S register S19 will be
       cleared.
    4) Cannot transfer file using XON/XOFF control:
       Modem hangs up the call when using XON/XOFF flow control for file
       transfer. And the disconnect reason shows "Local Hang Up".

 3. Fixed fax bugs:
 ------------------
    1) Fail to detect busy tone:
       After dialing out the number, the modem does not report "BUSY" when
       the central office sends busy tone to modem.
    2) Fail to go on-hook:
       If the modem answers a call with "AT+FCLASS=1;FAA=1;A" command and
       there is no response from remote modem, the modem will report
       "CONNECT", "ERROR" and then "OK". But actually the modem does not go
       on-hook.
    3) Wrong LED indicators:
       If DRAM is installed in modem and "AT+FZF=3" command is entered,
       the EC and SP LEDs keep on after pulling out the RS-232 cable.

 4. Fixed voice bugs:
 --------------------
    1) Fail to switch off the power to telephone jack:
       If "AT+FCLASS=8" and "AT+VLS=1" is given, the loacl telephone is still
       powered after "AT+FCLASS=0" command is entered.
    2) Wrong response to "AT+VSM" command:
       When "AT+VSM" command is entered with incorrect values, the modem does
       not respond with an "ERROR" message.
    3) Both V34 and V32b LEDs are not turned off in voice mode.

 5. Add new features:
 --------------------
    1) Support Russian CNI detection.

 6. Note:
 --------
    1) Change the default value of ring volume control from "N5" to "N3".



-----------------------------------------------------------------------------



             Release Note on Elite 2864 Version 1.07     Nov 16, 1995




 1. Improved V.34 performance.
 -----------------------------

 2. Fixed modem bugs:
 --------------------
   1) Wrong response to ATDT<phone number>;H command:
        the modem doesn't hang-up after dialing the phone number.
   2) Wrong response to AT&FX7S6=5&W1Z1 command:
        viewing the setting by AT&V, the modem responds with the default
        setting of X5 and S6=2, in stead of X7 and S6=5.
   3) Wrong AT command entered in escaped state will cause hang:
        if any wrong AT command is issued in escaped state, the modem will
        not respond to any futher AT commands. Modem should be powered off
        and on to reset.
   4) Modem hangs:
        when the modem is ringing and the RS-232 cable is pluged in, then the
        modem will not respond to any futher AT commands. Modem should be
        powered off and on to reset.
   5) Unable to send data calling tone for V.32b/V.22b/ZyX19200/ZyX16800
        modes.
   6) Connection problem when calling tone enabled:
        When the calling tone is enabled (AT&F&N0S48.2=1), the connection
        made with U-1496 plus models can only reach 16800 bps (the 19200 bps
        connection is not possible).
   7) Wrong LED display:
        When the modem is connected with ZyX 19200 or 16800 bps, the LED V34
        and V32b are ON. That is OK. But when you enter "+++" escape command
        and then "AT" command, the V32b LED goes OFF.
   8) The S14 register does not contain the exact value of the command AT*M0
        and AT*M1. For example, with command ATZ1*M1&V, the display shows the
        value of S14 bit 0 is 0; with command ATZ1S14.0=1&V, the display shows
        *M0.
   9) The supervisory password entry can take only 7 characters:
        Try setting for example password #8 but type more than 8 characters
        and you will get "ERROR".
  10) Problem of connecting to host with 7 data bits, even parity and 1 stop
        bit protocol:
        There is a problem when you try to connect to the "telebanking"
        service, where 7E1 protocol is used. What is supposed to happen is
        that you enter the user ID followered by <CR>, and then the host
        prompts you for the password. The bug is as soon as a numeric digit
        is entered, it behaves like a <CR> has been entered as well, and the
        host prompts for the user-ID again. After 3 incorrect attempts, you
        are automatically logged out.
  11) On the password table, for example setting *G4, the modem is not able
        to detect any password at location #10 to #49.

 3. Fixed fax bugs:
 ------------------
   1) In direct fax printing mode (AT+FCLASS=Z and AT+FZF=0), when a data
      call comes, the modem serial port will hang. (Can't switch from
      parallel port to serial port.)
   2) V34 and V32b LED doesn't goes off in FAX mode.
   3) CD on immediately after dialing in FAX Class 1 mode.
   4) In fax DRAM retrieing mode, the RS-232 RI signal is not sent to DTE
      when "RING" string is sent to DTE.

 4. New fax printing feature:
 -----------------------------
   1) Support Postscript Printer.
   2) Support HP DJ500 series Inkjet Printer.
   3) Support Serial Port Fax Printing.
   4) Speedup PCL Printing.
   New FAX feature Setting Registers:

     AT+FZT=? : View current setting of Fax Speed in Direct
                Fax Printing Mode.

   Usage of Direct Fax Printing via serial port:
   ---------------------------------------------
    1) Connect modem to PC via the RS-232 serial port.
    2) Use a terminal Software to communicate with Modem
    3) Set Baudrate = Serial Printer's Maximum Baudrate.
       (For example, if the max. baudrate of your serial printer is 38400,
        please use 38400 for terminal software)
    4) Setup S72. (0,1 for PCL, 2 for Postscript printer)
    5) Set AT+FZF = 0. (Direct Fax Printing)
    6) Set AT+FZT Value.
       (This value relies on the printer speed, baud rate of serial port and
        printing language (Postscript is faster than PCL).
        The principle on deciding this value is:

                  PRINTING MUST BE FASTER THAN FAX RECEVING!!!

        Because in AT+FZF=0 mode, received data is sent to printer directly.
        Therefore, fax printing speed must be faster than fax receving speed.
        Otherwise the internal buffer will overflow and some scanlines must
        be discarded.

        First, you can try AT+FZT=150. If it is OK, then you can try 100,
        64, 48, 32, 16 and 0 to get the optimal speed. This value depends on
        your printer's printing speed.

    7) Setup S73.
       (Configure fax printing options, bit 0 must be 1 for serial printing)
    8) If auto-receving is needed, please set S0=1.
    9) Set AT+FCLASS=Z. (Enable Fax Printing)
   10) Use AT&WZ to store current setting to profile 0.
       (Store All S-Regs and Baudrate Settings in EEPROM)
   11) Connect modem to printer Via the RS-232 serial port.

   Note: 1) In Serial Printing Mode, only DTR flow control is supported.
            Please setup your printer to accept DTR flow control.

         2) Because the modem's serial port type is of DCE type, the
            printer's serial port type must be of DTE type. If the printer's
            serial port is also of DCE type, a NULL MODEM adapter (or cable)
            is needed.

            <1> Modem in normal operation :
                             RS-232 Cable
                 Modem(DCE) <------------> PC(DTE)

            <2> Modem is connected to a DTE Serial Printer:
                             RS-232 Cable
                 Modem(DCE) <------------> Printer(DTE)

            <3> Modem is connected to a DCE Serial Printer:
                                          RS-232 Cable
                 Modem(DCE) <--> Adapter <------------> Printer(DCE)

         3) In order to achieve maximum throughput, please use the maximum
            baud rate your printer permits.

 5. Fixed voice bugs:
 --------------------
   1). Playing problem with 3-Bit ADPCM data.
   2). Increase the reliablity of VCON detection.
   3). Enhance the voice quality of local telephone phone set.

 6. Add new voice features:
 --------------------------
   1). When first playing through telephone line, the default setting is
       disable the Near Echo Cancellation. The users can enable this feature
       by setting the bit 7 of s60 to 1.

             Release Note on Elite 2864 Version 1.06     Sep 13, 1995


 1. Improved FAX V.17 receiving performance.
 2. Improved FAX V.21 sensitivity.
 3. Improved FAX printing quality.
 4. New FAX feature:
    (1) Function of s73 bit3:
        Set S-register s73 bit 3 to 1 (ATS73.3=1) will enable direct FAX
        printing application to print longer FAX pages to LETTER size paper.
        For off-line DRAM receiving and printing application, if s73 bit
        3 is set to 1 the printing driver will automatically and dynamically
        select a zooming factor and print the FAX pages to fit the selected
        paper size. The zooming factor depends on the page length of the
        received FAX. The default setting of this feature is on (s73 bit 3
        is set to 1).
    (2) AT+FZL? command:

 5. Fixed bugs:
    * FAX CNG tone transmitting:
      Sometimes it works but sometimes it doesn't work.
    * Data calling tone:
      When the data calling tone is enabled and a connection is made to another
      modem, the remote modem will show the wrong connect message like
      "CONNECT 115200/V.22 1200/NONE", but acturally the connection is not
      successful.
    * AT*Pn:
      AT*Pn can not be saved to profile. For example, originally at&f&v shows
      *P11. When at*p9&w0z&v is issued, the modem still shows *P11 instead
      of *P9.
 6. Improved performance on FRN (fast rate renegociation).

             Release Note on Elite 2864 Version 1.05     Aug 14, 1995


 Note: Version 1.03 and 1.04 are not formally released, their relase notes are
       accumulated here.
 1. Improved connectivity on noisy lines with some V.FC modems.
 2. Fixed bugs:
    * S38.5=1 does not disable MNP5
    * Wrong displayed FAX connect message for command ATX7#B1+FCLASS=6 string.
    * The top portion (0.5/1.0 inch) will be chopped in fax reception when a
      fax is received in class 2.0 mode.
    * The connect message of V.22bis (ATX7) was 2400/ARQ/V.22/V42b.
      It is corrected to 2400/ARQ/V.22b/V42b.
    * AT command response error:
        the response of AT&N after AT& was ERROR.
    * Wrong display of V34 and V32b LEDs. For example, when the modem
      connects in ZyX mode, both the V.34 and V.32 LED come on but when there
      is a retrain the V32bis LED goes off.
 3. When the DTE speed is set to 9600, the highest connection rate will be
    limited to 9600 bps.

             Release Note on Elite 2864 Version 1.02     Aug 01, 1995


 1. Fixed bugs:
    * ATS0:
        If you give ATS0=3 or other values, very often the modem answers on
        the first ring.
    * ATS1:
        The S1 register does not collect the number of rings received.
    * ATS38:
        The command S38=32 (or S38.5=1) that disables MNP5 doesn't work.
    * MNP hang:
        After retraining and connecting on MNP mode, the modem will "hang"
        and can not accept any command.
    * V32bis hang:
      When the modem is connected in V32bis, sometimes, the connection can
      not be dropped by lower DTR. The DTR LED is always ON and the modem
      has to be turned off.
    * The sending and reception of break signal does not work correctly for
      error control mode.
    * The response of ati2 command (following at&z? command) is incorrect.
    * When the modem is connected in V.22bis, the SQ LED will flash or
      always OFF.
    * When ATQ2 is issued, the modem still responds to EDR and gives RING
      message.
 2. ATI2 will display both transmission and receiving connection rate.
 3. Remove two <CR><LF> from at&v response.
 4. Add AT&N12 to on-line help menu.
