-
-
- 1. Fixed modem bugs:
- --------------------
- 1) Special dialing feature:
- .Modem does not finish dialing of numbers specified after P modifier
- and hangs for a time specified in S7 register. For example when
- "ATDT9WP8W10-886-3-578-7045" is entered, modem will report
- "NO CARRIER".
- .When bit 4 or register S35 is set, the modem will not dial the
- default phone number while the user press the DATA/VOICE switch in
- synchronous operation mode.
- 2) AT command and response:
- .When "AT&FX0" command is entered, the modem will report connect
- message as "CONNECT 38400" instead of "CONNECT" only.
- .When "ATM2" command is entered, modem will turn speaker off when
- retrain happened in ZyCell mode.
- .The modem does not prompt the hint message and erase the flash
- memory directly while the user keyin the "ATUPX" command with "ATQ1"
- disabling sending result code.
- .When the "AT&N65" command is entered, the modem will report some
- additional blanks in the "Last Speed/Protocol" field of "ATI2"
- command.
- .When "AT&M2X0" command is entered, the modem will response garbage
- and one more CR after connect message "CONNECT ".
- .When direct mode "AT&M2" command is entered,the modem will not send
- file correctly with 8E1 in data state.
- .When "LF" is entered after "AT<CR>" command in escape state, modem
- does not response "OK"
- 3) Security function:
- .When the call and anwer modems are entered with "AT&K0" and
- "ATS0=1*G5" respectively, the call modem can not enter the call
- back number after the connection.
- .When two Elite modems entered with the "AT&F&T4*F1S2=61" and "ATS0=1
- &T4*F1*G5" in call and answer mode respectively, the call modem can
- not read the remote configuration successfully.
- .When the level 2 security function is enabled, modem will request the
- user to key in the password with the "Password" prompt instead of
- "PassWord". Note that the "PassWord" prompt is used in ZyXEL U-series
- modem.
- 4) Physical layer stability:
- .ZyCell protcol can not accept any data from the remote site after
- the connect message.
- .When the "ATX6&N16&T1" is entered, modem will report "NO CARRIER" and
- modem will turn on CD when issue the "AT" command after the report.
- .Modem can not connect with Supra modem with V.34 mode under some
- worst line condition.
- .Modem will get a lower speed than the inital handshaking when the
- retrain procedues happened oftenly in data state.
- 5) Link Layer compatibility:
- .There is a compatbility problem with "Octocom" modem. When ZyXEL
- calls it with V.22bis/MNP4 mode, ZyXEL modem can not accept any
- data from it after the connect meessage be displayed.
- .In Italy, ZyXEL modem can only connect Digicom modem with error
- control mode under 26400 bps link speed. For 28800 bps link speed,
- the connection is non error control mode.
- .There are some characters will be missed in file transmission when
- software flow control XON/XOFF (&H4) is enabled.
- 6) V.25bis command set:
- .Modem will not support use profile 2 to make a connection with AS/400.
- 7) Error control procedure:
- .Improve the efficent in echo delay testing and file transfer with
- XMODEM protcol.
- 8) Diagnostic feature:
- When the call and answer modems are entered with "AT&F&T4&K3" and
- "AT&F&D0S0=1&T4" respectively, the TST LED of calling modem will turns
- on after the connection.
-
- 2. Fixed fax bugs:
- ------------------
- 1) If user want to print a fax, user issue "AT+FZP<CR>" and there
- should be <1F><OK> response from modem. But this does not happen
- and will cause problems in writing the application for this function.
- 2) Cannot receive a fax correctly after a V.34 data connection:
- 3) The modem will report incorrect result code to ZFAX when there are
- incomfing fax stored in DRAM and ZFAX try to retieve fax from modem.
- 4) Setting the modem with AT+FZF=1, 4 or 5 and DTR is off, the modem
- will answer the modem call instead of dropping the modem call.
- 5) When modem stayes in DRAM fax reciving mode (clsaa Z, +fzf=2) without
- RS-232 cable, modem can not accept AT command anymore after reciving
- a fax and plug in the RS232 cable.
- 6) When modem stayes in class Z service, modem can not make an outgoing
- data call.
-
- 3. Added new feature:
- ---------------------
- User can issue an "ATI12" command to get the physical layer parameters
- choosed in V.34 mode. This information is reliable only in the escape
- state. Since the Near End echo and Far End echo reports are not ready,
- they will be filled with "-xx.x" and will be implemented asap.
- One of the example is as following:
-
- ATI12
-
- ZyXEL MODEMS PHYSICAL LAYER STATUS REPORT
-
- Modulation mode = V.34
- Tx Carrier = 1600 Hz Rx Carrier = 1800 Hz

- "NO CARRIER". But the modem hang in an unknown state.
- 4) Incorrect password response in security function:
- When security function was enabled by AT*G5, the echoed password was
- followed by "<CR>" instead of "<CR><LF>".
- 5) Abnormal hang-up when security function was enabled:
- When the security function was enabled, the modem could not perform
- analog loop back test by AT&T1 command. The modem would hang up and
- report "NO CARRIER" immediately after connection made by "AT&T1"
- command. With ATI2 command, the disconnect reason was shown as
- "Security Check".
- 6) Wrong break handling:
- After pressing the control-break key, the TXD LED lights up for a very
- short time and the RXD LED lights up for a longer time. When the
- control-break key was pressed again, only the TXD LED lights up but the
- RXD LED remains off.
- 7) Did not report the first RING:
- For example, the auto-answer mode was enabled by setting S0=1. When the
- first ring signal came, the modem went off-hook directly and starts to
- handshake without reporting "RING" to the DTE.
- 8) Compatibility problem with Penril modem:
- When the modem was connecting with the Penril modem, the handshaking
- would fail during the phase 2 of V.34 hand shaking procedure.
- 9) Wrong help message:

- a wrong message "&N61 V.34b 31200" would be shown on screen with "AT&$"
- command.
- 10) Wrong indication of AA LED:
- The indication of AA LED was incorrect when the modem was set by the
- following command sequence:
- . AT&FS1=1&WZ :
- . AT&FS0=1 : AA LED lights on and indicates auto-answer mode.
- . ATZ : AA LED lights on but the S-register S0 is equal to 0.
- 11) Failed to respond to the ATX0D command:
- When "ATX0D;" command was entered, modem would hang and fail to
- accept the AT command.
- 12) Could not detect incoming ring signal:
- After executing "ATDxxxx;" and then "ATH" command, the modem would not
- be able to recognize the incoming ring signal.
- 13) Failed to dial with the synchronous V.25bis command:
- When the modem started dialing with the V.25bis "CRN" command, the
- dialing digits did not go through and then modem went on hook.
- 14) Failed to perform the analog loopback with self-test (AT&T8) in the
- non-error control mode (AT&K0).
-
-
- 2. Fixed fax bugs:
- ------------------
- 1) Wrong result with the "ATI2" command after FAX send/receive:
- After a fax connection, with the "ATI2" command, the modem reported
- the last baud rate with the wrong value of "28800".
- 2) Improved reliability of V.21 HDLC receiving.
- 3) The compatibility problem with Panasonic fax machine:
- When the FAX machine did not send the ANSWER tone, the modem would
- disconnect the outgoing call instead of sending out the fax.
- 4) The problem of the Postscript FAX receiving/printing fixed.
- Postscript printing margin can be configured by paper type.
-
- 3. Fixed voice bugs:
- --------------------
- Incorrect RI lead indicator of RS232:
- When modem went off-hook to answer the incoming call and play the voice
- greeting message in the voice mode, RI lead (pin 22 of RS232) kept high.
- Even aborting or terminating the voice playing, RI was still high.
-
-
- 4. New modem features:
- ----------------------
- 1) Support Germany message display for commands:
- . ATI2 : report link diagnostic status
- . AT&Vn : view current active or user profile settings
- . AT#B3 : measure the ring cadence
- . ATDL : dial the last-dialed number
- 2) When the DTE speed was set to 19200, the highest connection rate
- would be limited to 19200 bps.
-
-
- 5. New fax features:
- ---------------------
- A fax protocol capture utility was implemented for debugging the
- FAX compatibility problem. This feature is not available for the FAX
- direct printing mode.
-
- S76: bit0 = 1 FAX response capture enabled
- bit1 = 1 FAX command capture enabled
- bit2 = 1 V.21 HDLC Tx/Rx capture enabled
-
- Use "AT+FZX?" command to show the captured log on terminal.
-
-
- 6. New voice features:
- -----------------------
- 1) Add three sampling rate : 7200, 8000, 11025 bps
- 2) Add three digital compression algorithm : DVI ADPCM, A-law PCM,
- Mu-law PCM.
- 3) The command "AT+VSM=?" will show you how to use these new features.
- AT+VSM=?
- 2 ;ZyXEL ADPCM ;2Bit ;(7200,8000,9600,11025)
- 3 ;ZyXEL ADPCM ;3Bit ;(7200,8000,9600,11025)
- 30 ;ZyXEL ADPCM ;3Bit ;(7200,8000,9600,11025)
- 4 ;ZyXEL ADPCM ;4Bit ;(7200,8000,9600,11025)

- 81 ;Mu-law PCM ;8Bit ;(7200,8000,9600,11025)
- OK
- For example, to set DVI ADPCM with 8000 sampling rate, you use the
- command:
- AT+VSM=40,8000
- The power on default sampling rate is 2Bit ADPCM with 9600bps.
-

- 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 !
-
-
-

- 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:

-
-
- -----------------------------------------------------------------------------
-
-
-
- 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.

- +----------+-----------+---------+---------+
- 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.

- (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:
- Show FAX receiving log
- For example,
- No. Remote FAX ID Speed Pages Size Status Hardcopy Retrieved
- === ==================== ====== === ===== ====== ======== =========
- 1 886-35-782439 * 9600 3 110k OK YES
- 2 1-714-693-8811 14400 2 90k OK
- Free DRAM Size: XXX
- Where "No" ------------- Session log number
- "Remote FAX ID" -- Sending FAX machine indentifier (TSI)
- "Speed" ---------- Fax receiving speed and resolution
- "*" - fine resolution
- "Pages" ---------- Number of pages
- "Size" ----------- Log size (number of bytes)
- "Status" --------- Receivig result , "OK" or error code
- "Hardcopy" ------- FAX printing status
- "Retrieved" ------ Retrieved by FAX software if marked "YES"
- (3) AT+FZP=nn command:
- Print the received FAX by specifying the session log number "nn".
-
- 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).

- When there is no DTE connected with modem and modem is configured as
- the RDL granted, modem will hang if the remote site initiates
- the RDL action.
- .Failed to work with selftest in error control mode:
- When "AT&K2&T8" command is entered, the modem will not report the
- connect message and hangs in an unknown state.
- .Show incorrect test pattern:
- When "AT&T7" command is entered in escape state, the first character
- displayed in screen does not belong to the selftest pattern.
- .Fail to use the remote configure feature with V.22bis mode:
- When the "AT*W32" command is entered in the escape state with V.22bis
- connection, the modem will report "NO CARRIER" instead of "OK".
- 11) V25bis command set:
- Cannot dial with the V.25bis synchronous operation mode:
- When you plugs out the RS232 cable and then plugs in again, the
- modem can not accept the V.25bis synchronous command anymore.
- 12) Lockup problem:
- When the rate negotiation happens about one second after the
- connection, the modem lockups forever with blinking both V34 and
- V32b LEDs. And can not be abort with D/V key.
-
-
- 2. Fixed fax bugs:
- ------------------
- 1) Cannot answer the incoming fax with 2MB internal DRAM:
- When the modem with built-in 2MB DRAM and entered with "+FCLASS=Z
- +FZF=2 S0=2 &W0Z0" command, the modem will not answer the incoming
- fax automatically if the DTE is turned off.
- 2) Cannot receive a fax correctly after a V.34 data connection:
- If user switches between data and fax calling from the E2864 to
- a Motorola or receiving a data call from a Motorola modem the modem
- will hang up and it will no longer receive a complete fax call after
- any data call.

-
- March 14, 1996
-
- Release Note on Elite 2864 Version 1.12 (aka "CeBIT'96 Release")
- ----------------------------------------------------------------
-
-
- 1. Fixed modem bugs:
- ---------------------
- 1) Failed to work with the external sync clock:
- In the external synchronous clock (AT&X1) mode, the modems could
- connect to each other but had a lot of bit error.
- 2) The O288S firmware could not recognize the incoming ring signal in
- Germany.
- 3) Modem hang when security function enabled:
- When the security function was enabled by AT*G1 or AT*G2 and the
- entered password was wrong, the modem should hang up and report
- "NO CARRIER". But the modem hang in an unknown state.
- 4) Incorrect password response in security function:
- When security function was enabled by AT*G5, the echoed password was
- followed by "<CR>" instead of "<CR><LF>".
- 5) Abnormal hang-up when security function was enabled:
- When the security function was enabled, the modem could not perform
- analog loop back test by AT&T1 command. The modem would hang up and
- report "NO CARRIER" immediately after connection made by "AT&T1"
- command. With ATI2 command, the disconnect reason was shown as
- "Security Check".
- 6) Wrong break handling:
- After pressing the control-break key, the TXD LED lights up for a very
- short time and the RXD LED lights up for a longer time. When the
- control-break key was pressed again, only the TXD LED lights up but the
- RXD LED remains off.
- 7) Did not report the first RING:
- For example, the auto-answer mode was enabled by setting S0=1. When the
- first ring signal came, the modem went off-hook directly and starts to
- handshake without reporting "RING" to the DTE.
- 8) Compatibility problem with Penril modem:
- When the modem was connecting with the Penril modem, the handshaking
- would fail during the phase 2 of V.34 hand shaking procedure.
- 9) Wrong help message:
- If the multi-language feature of Germany version was enabled (S63=1),
- a wrong message "&N61 V.34b 31200" would be shown on screen with "AT&$"
- command.
- 10) Wrong indication of AA LED:
- The indication of AA LED was incorrect when the modem was set by the
- following command sequence:
- . AT&FS1=1&WZ :
- . AT&FS0=1 : AA LED lights on and indicates auto-answer mode.
- . ATZ : AA LED lights on but the S-register S0 is equal to 0.
- 11) Failed to respond to the ATX0D command:
- When "ATX0D;" command was entered, modem would hang and fail to
- accept the AT command.
- 12) Could not detect incoming ring signal:
- After executing "ATDxxxx;" and then "ATH" command, the modem would not
- be able to recognize the incoming ring signal.
- 13) Failed to dial with the synchronous V.25bis command:
- When the modem started dialing with the V.25bis "CRN" command, the
- dialing digits did not go through and then modem went on hook.
- 14) Failed to perform the analog loopback with self-test (AT&T8) in the
- non-error control mode (AT&K0).
-
-
- 2. Fixed fax bugs:
- ------------------
- 1) Wrong result with the "ATI2" command after FAX send/receive:
- After a fax connection, with the "ATI2" command, the modem reported
- the last baud rate with the wrong value of "28800".
- 2) Improved reliability of V.21 HDLC receiving.
- 3) The compatibility problem with Panasonic fax machine:
- When the FAX machine did not send the ANSWER tone, the modem would
- disconnect the outgoing call instead of sending out the fax.
- 4) The problem of the Postscript FAX receiving/printing fixed.
- Postscript printing margin can be configured by paper type.
-
- 3. Fixed voice bugs:
- --------------------
- Incorrect RI lead indicator of RS232:
- When modem went off-hook to answer the incoming call and play the voice
- greeting message in the voice mode, RI lead (pin 22 of RS232) kept high.
- Even aborting or terminating the voice playing, RI was still high.
-
-
- 4. New modem features:
- ----------------------
- 1) Support Germany message display for commands:
- . ATI2 : report link diagnostic status
- . AT&Vn : view current active or user profile settings
- . AT#B3 : measure the ring cadence
- . ATDL : dial the last-dialed number
- 2) When the DTE speed was set to 19200, the highest connection rate
- would be limited to 19200 bps.
-
-
- 5. New fax features:
- ---------------------
- A fax protocol capture utility was implemented for debugging the
- FAX compatibility problem. This feature is not available for the FAX
- direct printing mode.
-
- S76: bit0 = 1 FAX response capture enabled
- bit1 = 1 FAX command capture enabled
- bit2 = 1 V.21 HDLC Tx/Rx capture enabled
-
- Use "AT+FZX?" command to show the captured log on terminal.
-
-
- 6. New voice features:
- -----------------------
- 1) Add three sampling rate : 7200, 8000, 11025 bps
- 2) Add three digital compression algorithm : DVI ADPCM, A-law PCM,
- Mu-law PCM.
- 3) The command "AT+VSM=?" will show you how to use these new features.
- AT+VSM=?
- 2 ;ZyXEL ADPCM ;2Bit ;(7200,8000,9600,11025)
- 3 ;ZyXEL ADPCM ;3Bit ;(7200,8000,9600,11025)
- 30 ;ZyXEL ADPCM ;3Bit ;(7200,8000,9600,11025)
- 4 ;ZyXEL ADPCM ;4Bit ;(7200,8000,9600,11025)
- 40 ;DVI ADPCM ;4Bit ;(7200,8000,9600,11025)
- 80 ;A-law PCM ;8Bit ;(7200,8000,9600,11025)
- 81 ;Mu-law PCM ;8Bit ;(7200,8000,9600,11025)
- OK
- For example, to set DVI ADPCM with 8000 sampling rate, you use the
- command:
- AT+VSM=40,8000
- The power on default sampling rate is 2Bit ADPCM with 9600bps.
-
-
-
- Known bugs of v1.12: ("very sorry, very sorry - it's not perfect yet")
- These bugs were recognized on March 14th, 1996:
- ------------------------------------------------------------------------
- 1) The modem has problem with 11-bit character length.
- 2) Remote configure (*Wab) fails over V.22bis connection.
- 3) Security function (*G3) fails and causes modem reset.
- 4) Connect with V.22bis (2400 bps) with MNP5 data compression
- will transfer no data - please disable MNP5 feature with ATS38.5=1

- ---------------------------------
-
- 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 !
-

- 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.

-
-
-
- -----------------------------------------------------------------------------
-
-
-
- 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.

- +----------+-----------+---------+---------+
- 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.

- 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:
- Show FAX receiving log
- For example,
- No. Remote FAX ID Speed Pages Size Status Hardcopy Retrieved
- === ==================== ====== === ===== ====== ======== =========
- 1 886-35-782439 * 9600 3 110k OK YES
- 2 1-714-693-8811 14400 2 90k OK
- Free DRAM Size: XXX
- Where "No" ------------- Session log number
- "Remote FAX ID" -- Sending FAX machine indentifier (TSI)
- "Speed" ---------- Fax receiving speed and resolution
- "*" - fine resolution
- "Pages" ---------- Number of pages
- "Size" ----------- Log size (number of bytes)
- "Status" --------- Receivig result , "OK" or error code
- "Hardcopy" ------- FAX printing status
- "Retrieved" ------ Retrieved by FAX software if marked "YES"
- (3) AT+FZP=nn command:
- Print the received FAX by specifying the session log number "nn".
-
- 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).
