Zoom now has most contact info on their WWW site:
http://www.zoomtel.com/contacts.html

-----------------------------------------------------------------------
The FAX number listed on some of the Zoom warranty cards (423-9231) is 
INCORRECT. 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.

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:

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.

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

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

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).
