That is the OLD Zoom SALES fax number- I listed the new one above. The Tech Support fax number is correct in the users manual- and above. You can use the toll free phone numbers for ROM replacements and to get an RA number if you have to send in your modem for repairs. Each of the online services and the BBS have seperate Zoom tech support representatives. The zoomrep email address has more than one. So, if you're not satisfied by one tech support method, you can try another. Some are much quicker than others- and some may give you better answers. It seems that when one person is on vacation, even for a week, there is no replacement. Therefore, some support options take longer on one week, but faster on most weeks. Zoom recommends that Internet users use the Tech Support page on their WWW site (listed above) to leave a msg to tech support. The tech support page, though, seems to take a long time to get a reponse from. Zoom is still searching for a good search engine for self-help on their WWW site. ----------------------------------------------------------------------- II. Other sources of modem help. a. Zoom information especially for European users (not Zoom itself)! Packlink/Zoom Modem Support sysop@f235.n254.z2.fidonet.org BBS +441812972486, +441812972488 (7pm-7am GMT) Most Zoom help files from Zoom's Boston BBS available at this location Fidonet Netmail 2:254/235 a1. Note for European users Since many European countries have restrictions on modem use, Zoom (like other modem manufacturers) has certain 'features' on its World Class modems. As a result, there may be BLACKLISTED numbers which you can not dial - and a DELAY (usually 30 seconds) between each number dialed- no rapid redial. This is the NORMAL way the European modems are set up and is NOT a defect with your modem. b. Other sources Besides Zoom's WWW site, BBS and faxback, Rockwell's WWW site has some useful information. http://www.nb.rockwell.com The BAUDMAN (Baud-A-Cator) section is very useful and contains various FAQs and manuals. The BAUDMAN is back to answer your Rockwell modem chip (Zooms use Rockwell chipsets) questions! baudman@nb.rockwell.com Having problems installing your modem in Win95? First contact Zoom. COMSTAR installation help is listed below. If that doesn't help, try the below URL for generic Rockwell chipset modem installation help: http://www.nb.rockwell.com/ref/win95modem.html You may want to try selecting "Record a Log File" so that you can get detailed information showing the commands to the modem and its responses. This option is found in the "Modems" option of the "Install New Modem" Wizard. Look at the log file that it creates called Modemlog.txt . Rockwell has generic AT command set reference manuals available for display and download. As these manuals are generic for Rockwell chipset modems, Zoom may add, delete or change some of the commands. http://www.nb.rockwell.com/ref/at_commands.html Another interesting WWW site is John Navas' modem FAQ. Look there for solutions to common high speed modem problems. The site includes current modem news, modem help (including data overruns, IRQ conflict, Winsock, Win95 modem questions and much more), and explanations of many high speed modem technical terms. Although somewhat controversial - he does have a USR slant and doesn't realize that the Zoom v.34, as of ROM 1.309, has many of the 'advanced features' he mentions - it is very informative. http://web.aimnet.com/~jnavas/modem/faq.html Check out the Usenet newsgroups (sometimes called Netnews) called: comp.dcom.modem General modem discussions comp.sys.ibm.pc.hardware.comm IBM-PC & general modem discussions comp.sys.mac.comm For Macintosh communications MAC communications FAQ: http://www.cis.ohio.state.edu:80/hypertext/faq/usenet/macintosh/comm-faq/ top.html RPI help is listed in the RPI section of this file. ----------------------------------------------------------------------- III. Zoom V.FC (VFX or VFP) to V.34 upgrade program info. The upgrade from the Zoom V.Fast Class 28.8 modem (VFX or VFP 28.8K) to v.34 is $89. From the 24k V.FC modem (VFX or VFP 24K) to v.34 is $109 Get the upgrade form from the Zoom WWW site, faxback, BBS or call the Toll Free Zoom Sales number. ----------------------------------------------------------------------- IV. Zoom V.34i/V.34x ROM info Newest Zoom V.34 ROM (U.S.) version 1.309 - Contact Zoom (you could use the toll free phone number) for free upgrade that you install- instructions below. Zoom should be releasing a new ROM soon (whatever that means)- keep your eyes out for it. This ROM is NOT for the old Zoom V.FC modems. The last ROM for the Zoom V.FC models is 1.000d for the internal VFP and 1.000h for the external VFX. To check what version ROM you have, type at i3 in your communications program. Improvements: A) Fixed dropped carrier problems B) Increased connect speed C) Improved LAPM -- added SREJ (Selective Rejection) D) Fixed adaptive answering -false fax receive detection- problem E) SPLIT/ Asymmetric speeds NEW undocumented S210 register! QIC HINT FROM PACKLINK/ZOOM MODEM SUPPORT (Richard Town) ========================================= Split speed (assymetric channeling) has been enabled on the Zoom V34 series from ver1.309 ROM upwards It may be disabled by adding the command: s210=5 (assymetric channeling disabled) S210=13 (default, or assymetric channeling re-enabled) Other values for S210: S210 Available symbol rates Supported data rates (bps) ===== ============================ ========================== =0 2400 2400 to 21600 =1 2400 2400 to 21600 =2 2400, 2800 2400 to 24000 =3 2400, 2800, 3000 2400 to 26400 =4 2400, 2800, 3000, 3200 2400 to 28800 =5 2400, 2800, 3000, 3200, 3429 2400 to 28800 to your init string. The receive channel speed may be observed from setting a CARRIER report instead of CONNECT. Setting S95=47 should do. Although other Rockwell marques have differing S95 settings available ... These settings can be used if connecting with (usually some older v.34s) that have a bug with certain symbol rates. >There are probably more settings for the S210 register, but they are currently unknown. - I love undocumented commands! :) < If your having trouble connecting to a modem that has a problem with the 3429 symbol rate you can: A)Force V34 up to max 26k4 with AT+MS=11,0,,26400 B)Force V.FC at up to max 28k8 with AT+MS=74,0,,28800 C) IF you have 1.309 Rom or later, do as above: use ATS210=4 to limit the symbol rate and still have the possibility of a v.34 28.8 connection (but it's then not split speed) NEW UNDOCUMENTED AT %Q1 COMMAND In ROM version 1.309 the %q1 command was enabled. This command only works in v.34 mode. This info supplements the info available by at %q %l . To use the %q1 %q or %l commands you must go to command mode while on-line. Press the +++ and wait a second. It'll say OK - then type the commands that you want. To go back to the system that you were on (if the system allows you to) type ato or ato1. That's the letter o not a 0. ato1 starts a retrain to adjust to current line conditions, while ato keeps the same speed as you had before. FYI, the modem automatically changes speed while you're on-line to adjust to current line conditions. Here is a breakdown of what at %q1 returns (from Kiwin (Stephen) Palm): Here is an example output from the AT%Q1 command: 005 028 038 000 002 | | | | | | | | | \___ Pre-emphasis | | | \_______ TX Level Reduction | | \___________ Total Harmonic Distortion (THD) | \_______________ Signal to Noise Ratio Index (Not in dB) \___________________ Symbol Rate Index It shows a fairly decent connection, when interpreted with the following: Symbol rate index (higher the better) 0 = 2400 -Supports up to and including 21600 BPS 2 = 2800 -Supports up to and including 24000 BPS 3 = 3000 -Supports up to and including 26400 BPS 4 = 3200 -Supports up to and including 28800 BPS 5 = 3429 -Supports up to and including 28800 BPS SNR - Signal to Noise Ratio Index The reported value is a raw value. To convert to dB use: db= raw*1.7 -7 Thus for the example (28*1.7-7) it is about 40dB THD Total Harmonic Distortion TX Level Reduction - just indicates how many dB lower the transmitter is feeding the central office. Zero through E (hex) in -dBm Pre-Emphasis - Pre-emphasis is a linear equalization method where the transmit signal spectrum is shaped to compensate for amplitude distortion. - There are 11 different filter spectrums for various tuning to the local loop. They are labled 0 - A. ------------------ a. SIMPLE FIX FOR SPEAKER PROBLEM IN WIN95 --------------------------------------- There is a slight ROM bug that makes the speaker mute in Windows95. While the below simple fix will generally work, some comm programs may assume that you have the semi-colon there and not work properly if you plan on dialing more digits after the connection has already been made. If you do plan to dial more digits after the initial connection, you could probably still add commas to the end of the phone number, before the extra digits, to make your modem wait a few seconds before continuing to dial. This is the way it has been done for years. Hopefully a new ROM will correct the problem. In your C:\WINDOWS\INF there is a file named MDMZOOM.INF. First, make a backup of that file. Then, load that file into a text editor such as MS-DOS's EDIT. Do a search for ";" (parenthesis included) and replace with "" (remove semicolon)-double check that you're editing the correct line. The original line HKR, Settings, DialSuffix,, ";" should now be HKR, Settings, DialSuffix,, "" After you save the changes to MDMZOOM.INF. Go into the Control Panel and double click on the modems icon. Delete the entry for the modem, then re-add it. If this causes any problems (none are expected), you could just reenter the semi-colon or use your backup copy. ----------------- One MAC user on comp.dcom.modems said that he has problems with hardware flow control with this ROM and not with a previous ROM. ---------------------------------------------------------------------- b. MAC SETUP INFORMATION WITH ROM 1.309 ===================================== While the old ROM defaulted at &c0 &d0, the NEW ROM defaults at &c1 &d2 the setting ideal for PC's. While you may not have problems with this setting, you should make sure that you change your initialization string anyways by adding &d0 To put it into NVRAM type at &d0 &w Reinitialize the modem and software or type at &d0 by itself to activate it for the first time. ---------------------------------------------------------------------- V. NOTES ON CHANGING ROMS ====================== These instructions were written for the v.34 modems, but they are more or less applicable to all Zoom modems. Take normal Static Precautions. -From Posting by Richard Town If you've never changed a ROM chip before and feel a bit put off by doing it yourself, then ask your supplier who'll be glad to help There is a proper chip-puller tool (available from Maplins [or Radio Shack in the U.S.] and any other good hobbys electronic parts outlet). Switch off your computer, switch off your monitor, switch off at the mains. Unplug your monitor from the supply (either at rear of your computer or at the mains), unplug your computer. Unplug your modem's power cube (if external) Remove the 'phone lead from your modem, remove the data lead (if an external modem). For Internal Modems ------------------- Remove your computer's case. Gently remove the modem card from its slot. Place the two inward pointing prongs of the chip puller between the old chip (you can recognize it as the only one looking exactly the same as your replacement) and it's socket. On each of the short sides there should be a very slight gap. Gently squeeze the puller and the prongs should enter the gap. Gently rock the chip puller from left to right and you will see each side of the ROM chip slowly rise. As it rises you can gently decrease the "pull" pressure upwards away from the modem. It will slowly become more free. Take the replacement ROM from its protective plastic case and hold length -wise between thumb and forefinger. The chip's label should not be upside down! Check that it's the same way round as the way the original was socketed! Place the new ROM over the vacant socket and gently squeeze the pins until they are exactly over the socket's holes. Insert pins into socket all the way along the chip's length. When both rows of pins are correctly located into socket, gentle thumb pressure will seat the chip firmly into socket. Do not press too hard! Zoom Telephonics' products are warrantied for seven years for the US versions and are subject to continual improvement. Do leave a slight gap (say 1/16 inch between chip and socket) so if you need to update ROMs again it'll be easier to change chips if another update is issued. For External Modems ------------------- There are two screws that hold the board down and two hex nuts on the back which hold the RS232 socket. Remove all of these, then the modem's circuit board. Now you can unbend the metal tabs which hold the metal shielding on the top of the board and remove the shielding. Once you have the shielding off, it's just a matter of swapping the ROM chips as for the internal modem. Be careful, the ROM in mine was in tight with no gap between the chip and its socket making it hard to get anything in to lever it up. IF YOU ARE NOT HAPPY ABOUT DOING IT YOURSELF THEN DO TAKE YOUR MODEM AND REPLACEMENT CHIP BACK TO YOUR RESELLER. ----------------------------------------------------------------------- VI. Zoom 14.4 EX/PC -(RPI/WinRPI) info. ******Rockwell has released a v.34 chip with RPI+. I don't know if Zoom is planning to use it or not. If they do, then most of the below information should apply to those modems as well.******* The EX and PC models (unlike other Zoom 14.4 models) need special software to be able to support Error Checking and Data Compression (ECC) since they use RPI (Rockwell Protocol Interface- a description of RPI is given in the Rockwell RPI FAQ- the URL is listed below). The WinRPI free software driver gives this functionality to just about any Windows program. Newer versions of these Zoom modem models come with WinRPI on the COMit disk. Of course, even if your RPI modem came with WinRPI, CHECK TO SEE THAT YOU HAVE THE LATEST VERSION. If you don't, then get it from Zoom's or Rockwell's WWW site listed below. The Zoom's installation program is better than Rockwell's, as it actually tests the capabilities of your modem before installation. Zoom's version can also update your COMit installation, if you have COMit on your system. On the other hand, the drivers on Rockwell's WWW site are newer- with bug fixes. For 14.4 EX and 14.4 PC (including models 100 and 110) - which are RPI or RPI+ modems: Serial # xxxZA1ixxx or xxxZA2ixxx are plain RPI (older) models If you type at i3 you'll get the ROM version which would also say RPI or RPI+ after it. The '+' is at the end of the line, not immediately after the letters 'RPI'- the RPI+ message will look something like this. AFEP-V1.xxx-BP39 ROCKWELL RPI (TM) MODEM+ If after typing at i3 your modem returns something like this: V2.400-ACF_DP ROCKWELL RPI (TM) MODEM+01 That is, it says "ACF" (the rest depends upon the version)- EVEN THOUGH IT SAYS RPI+, it ALSO has built in hardware ECC, so WinRPI is NOT needed. Rockwell has released both 14.4 and 28.8 chips with this configuration. I don't know if any Zoom models have this chip installed yet.Look at Rockwell's list on their WWW site (URL listed below) and explanation of RPI chips to make sure whether or not you have an RPI or RPI+ only chip, RPI+ and hardware ECC or just hardware ECC. No new modems are being produced with the plain old RPI chips- they are all RPI+. Check to make sure that you have the current ROM version. If not, contact Zoom (you could use the toll free number) to get a replacement ROM for you to install. Since the older models use different ROMs than the newer ones, you'll have to ask Zoom what the newest version is for your modem. The current ROM for the newer 14.4 RPI models is 1.625. Look at section V. for general ROM installation instructions. Zoom has WinRPI on their WWW site. It has the older 2.23 WinRPI drivers. I would STRONGLY advise using the wrpi_226 driver below and not the Zoom driver. The Zoom driver is older and contains more bugs. http://www.zoomtel.com/files/rpikit4.exe Rockwell has released WinRPI version 2.26 (for WIN 3.1)- Bug fixes which may help any problems that you are having- give it a try! http://www.nb.rockwell.com/ref/rpi/wrpi_226.zip WINRPI for WIN95 - version 1.15. Includes INF file for RPI modems including v.34 RPI modems. Remember that if you are using Win 3.1 comm applications inside WIN95, you still have to change the init strings in the individual applications. http://www.nb.rockwell.com/ref/rpi/95RPI115.ZIP Instructions for WinRPI installation- including how to change your initialization string in your communications program (e.g. Procomm, America OnLine, Winsock) - WHICH IS VERY IMPORTANT- are included in each package. Zoom has more application specific (America OnLine etc.) information on its WWW site. The FIFO or AOL problems that are mentioned there may or may not apply to you. I would advise trying the 2.26 WinRPI drivers The author of those information files has tried WinRPI 2.26 since the writing of those files and now advises using 2.26. He had problems on AOL which were fixed when using the 2.26 WinRPI version. (The URL for WinRPI 2.26 is above) http://www.zoomtel.com/rpi_file.html Rockwell has an unofficial list of DOS and Windows communications programs that support RPI (without using the universal WinRPI Windows driver): http://www.nb.rockwell.com/ref/rpi.software.info If you use a Windows program that has RPI support built in, and you have WinRPI installed, you must disable either RPI support in the program or WinRPI. Rockwell has a very extensive FAQ (Frequently Asked Questions) file about RPI and WinRPI. The file has already been updated a number of times, so check it periodically. Zoom now has a link to this FAQ from their homepage. http://www.nb.rockwell.com/mcd/bman/rpi_faq.html The instructions with some of the WinRPI drivers tell you to change the S95 register so that your modem will return a more informative CONNECT string (including whether or not you have made a error corrected and/or data compressed connection). Also, your RPI modem returns TWO sets of CONNECT info- first saying no ECC- then saying yes ECC once WinRPI kicks in. The problem is that some script files (e.g. in Trumpet Winsock, Chameleon or script files in a communications program) don't like this extra (or different) info. As a result, your communications program may never know that you're connected and will keep waiting for your modem to connect. Therefore, IF you have a problem- either change your S95 register (using the below table as a guide) - or tell your script file to search for the more complex CONNECT string. On RPI (non-RPI+) modems, there is a 'display' setting in the applet that comes with WinRPI instead of the S95 register. S95 register- add numbers for message desired-(valid for RPI+ and modems with hardware error correction) 0 CONNECT DTE (computer to modem) speed 1 CONNECT DCE (modem to modem) speed 2 /ARQ if error correction 4 CARRIER 8 PROTOCOL 32 COMPRESSION For example: at s95=1 will return CONNECT 14400 when connected at 14400. at s95=47 will return ALL the above info. RPI+ models use standard AT commands to control ECC. Plain RPI models have their ECC controlled via an applet that comes with WinRPI. Also, on plain RPI models, you must disable WinRPI (with the applet that comes with the WinRPI driver) before using fax mode. You do NOT do this with an RPI+ model. Older RPI models don't support WinRPI. ----------------------------------------------------------------------- VII. COMSTAR INSTALLATION INFORMATION Important Notice (This message is from the Zoom BBS): If SETMODEM.EXE terminates upon installation before completing its execution and displays the message, "abnormal termination error", this could be due to a conflict with another device in your system, i.e. a soundcard. In that case, there are two other utilities that allow you to configure your modem. First, to determine the available comports in your system, run the ZPORTS.EXE program included on this disk. From a DOS prompt and this disk, type ZPORTS and press ENTER. ZPORTS will suggest a combination of comport and possible IRQs that the modem could use. Secondly, run the SETPORT.BAT utility using the settings provided by ZPORTS. For example, if ZPORTS suggests COM 4, you would type SETPORT 4 and hit the enter key. Then, if the program didn't confirm that the modem was set up on COM 4, you could try COM 4 with a different IRQ than the default. To try COM 4 on IRQ 5, for example, you would type SETPORT 2E8 5 and hit enter. Please note that when you need to try an IRQ that is different than the default, you need to enter the hex address rather than the number of the comport. Please refer to the tables below for different comport/IRQ combinations. Modem set to: If the ZPORTS info fails, Typing = Comport IRQ try SETPORT in this order: ---------------------------------------------------------------------- SETPORT 1 = 1 4 (default IRQ) SETPORT 2 = 2 3 (default IRQ) 1 SETPORT 3 = 3 4 (default IRQ) SETPORT 4 = 4 3 (default IRQ) SETPORT 3E8 5 = 3 5 2 SETPORT 2E8 5 = 4 5 4 SETPORT 3E8 7 = 3 7 3 SETPORT 2E8 7 = 4 7 5 Comport Hex Address Reference Table: ------------------------------------ COM 1 = 3F8 COM 2 = 2F8 COM 3 = 3E8 COM 4 = 2E8 Note: SETPORT.BAT runs a file called PORTWIZ.EXE which actually does all the work. If PORTWIZ is successful in configuring your modem, it will ask you if you want to add it to autoexec.bat so that your modem is configured automatically each time you start your machine. This is a good idea. In order for PORTWIZ to work from autoexec.bat, there has to be a copy of it in your root directory. SETPORT.BAT does this when you run it. This means is that you will only have to run SETPORT during installation to find a configuration that works in your system. Thereafter, each time you restart your computer after that, your modem will be automatically configured on a comport/IRQ when autoexec.bat runs at boot time. --------------- Files of interest (on the BBS, AOL, CIS and WWW servers) to COMSTAR users: Setmodem.zip Revision D modem installation files including COM/IRQ setup programs (e.g. setport and portwiz) and a new .inf file for WIN95. Bitware2.zip The second Cheyenne Bitware disk (without current above files) -------------------------------- a. MORE GENERAL COMSTAR INSTALLATION INSTRUCTIONS To set up the Comstar in Windows 95, remove any old modems and sound card(temporarly until after setup) from your computer if you have them. In Control Panel>System>Device Manager, Remove any modems under Modem and remove ALL Com ports under Ports. Then go to Add New Hardware and let Win 95 detect the modem. IF THE MODEM IS DETECTED ON COM5, then do the following. DO NOT USE SETMODEM, PORTWIZ, SETPORT, etc. Goto Control Panels>System>Device Manager>Modem>ComStar 28.8(14.4). Click on Properties>Resources and take the check out of "use automatic settings" Change to basic configuration 002. Click on Change Setting. Using the up/down arrows,change the address to 03E8-03EF Click on OK. Highlight the IRQ selection. Click on Change Setting Change the value to 05 (or 07 if 05 shows a conflict) Click on OK and then OK again. The modem is now set to Com3 with irq 5. Select a different address and IRQ if Com3 is in use. Happy modeming Joe Zoomrep If you have a PCI bus and are having a problem with installation, continue reading. b.IMPORTANT COMSTAR INFORMATION FOR COMPUTERS WITH PCI BUS The "floppy drive controller error" problem you are having is due to a conflict due to the PCI BUS, Floppy controller starting address and the PnP modem starting address. About 30% of the P5 systems have the same type controller that you do and exhibit this problem in one of several ways. Rockwell Int'l (the makers of the modem chipsets) is currently working on a workaround for this. In your Computers BIOS settings, try changing the PnP BUS type to ISA instead of PCI. In Windows 95, 1. Remove all Comports but Com1 in the Device Manager. 2. Remove any modems (none but the Comstar should be in the computer at this point) from the Device Manager. 3. Remove the PCI BUS from the System Devices portion of Device Manager. 4. Restart the Computer and allow Windows95 (if you get this far) to install all new Hardware. Please let me know how you fare. Regards, Chris, Zoom Tech ---------------------------------- From another tech support representative: If your bios does not have the PCI to ICU option, follow these instructions: In control panel>system>device manager>system devices, remove the PCI plug n play bus. Then go to Add new hardware and MANUALLY add system devices>ISA plug n play bus. Click thur next until you get to finish. Happy modeming Joe Zoomrep ----------------- c.Comstar continued.... If you can't get your modem to work using a 32 BIT (Win95) comm software, then it is possible that the registry has AT&FE0V0&C1&D2S95<cr> instead of the complete AT&FE0V0&C1&D2S95=47S0=0<cr> Therefore a mistaken init string is sent to the modem. The ModemLog.txt file may say that the correct string was sent, even though it wasn't. Take a look at Microsoft's Zoom COMSTAR problem sheet on their WWW/gopher/ftp sites. It's document Q146639. d.NEW COMSTAR ROM On Friday Jan 26th, Zoom released a new ROM for the COMSTAR. As of yet, I don't know which model it is for or what it fixes. I haven't gotten a straight answer from Zoom yet. Give them a call and ask for it. ----------------------------------------------------------------------- VIII. General Info ALWAYS UNPLUG YOUR MODEM FROM BOTH POWER AND PHONE LINES BEFORE A THUNDER STORM! The majority of modem breakage occurs from lightning damage. Zoom modems do have built in surge protection (the COMSTARs have even greater surge protective devices) - but nothing will protect from a direct lightning strike. To improve communications reliability with high speed modems using Windows 3.x (not Win for Workgroups 3.11 or Win95) with your 16550A UART, you should install an enhanced comm driver such as the one that comes with Winfax - also available at: http://www.cdrom.com/pub/cica/misc/wfxcomm.zip Before purchasing any modem of any brand, make sure that the store in which it was purchased has a good return policy. This will allow you to make sure that the modem works well with your computer and phone lines- and with the phone lines and modem on the end of the services that you are connecting to! Once you have purchased a modem, call the manufacturer to make sure that you have the current firmware. Many manufacturers (including Zoom) will send out updated ROMs for free- at least while the modem is under its 7 year warranty and they still produce the modem (or have ROMs leftover). ----------------------------------------------------------------------- TO RECEIVE WWW (World Wide Web) DOCUMENTS VIA EMAIL - (You do not need World Wide Web access- only Internet Email) agora@capri.mi.mss.co.jp Type SEND then the URL. webmail@www.ucc.ie Type GO then the URL (address). w3mail@bagheera.gmd.de Type GET then the URL.
