Zoom now has some 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. Zoom  
recommends that Internet users use the Tech Support page on their WWW
site (listed above) to leave a msg to tech support. I haven't tested 
it. Zoom is still searching for a good search engine for self-help on
their WWW site.

-----------------------------------------------------------------------
II. Other sources of modem help.

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

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  
The upgraded model is refurbished- even if you do an advanced replacement.
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 version 1.309  - Contact Zoom (you could use the toll
free phone number) for free upgrade that you install- instructions below. 

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.

The ver1.309 ROMs do _not_ apply to the WorldWide chipset (as used in the
BABT approved V34) (--Richard Town)

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- problem 
E) SPLIT/ Asymmetric speeds 
----------------------------------------------------------------------

a. 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. The MAC, doesn't support the DTR
(Data Terminal Ready) pin. While you may not have problems with this 
setting, you should make sure that you change your initialization string 
anyways by adding                   &c1 &d0 
To put it into NVRAM type           at &c1 &d0 &w
Reinitialize the modem and software or type at &c1 &d0 by itself to activate 
it for the first time. 

----------------------------------------------------------------------
V. NOTES ON CHANGING ROMS  -From Posting by Richard Town
   ======================
These instructions were written for the v.34 modems, but they are more or
less applicable to all Zoom modems. 
Take normal Static Precautions. 

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) for around #2.

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 
going 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. At the moment, it 
only supports WIN 3.1 -- Rockwell is working on a WIN95 version. Latest ETA 
Jan. 96. Keep your eye on Rockwell's RPI page. Some users have posted msgs 
saying that WinRPI 2.26 will work with some comm software in Win95. The 
installation instructions are found in Rockwell's RPI faq. (Get WinRPI 2.26 
and the FAQ at the URLs below) If you do try it- it is at your own risk- as 
the driver was NOT designed for Win95. 

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. It also installs a comm driver to boost performance using your 
16550a buffered UART (internals have them built in- for externals your serial
card has the UART). Zoom's version can also update your COMit installation, 
if you have COMit on your system. If you don't use Zoom's version of WinRPI, 
you could always install another enhanced comm driver such as the one that 
comes with Winfax - also available at:
http://www.cdrom.com/pub/cica/misc/wfxcomm.zip 

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+ 

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 models is 1.625. Look at section V. for 
general ROM installation instructions.

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. 

Zoom has released a new version of WinRPI (for WIN 3.1) on their 
WWW site. It still seems to have the older 2.23 WinRPI drivers though. 
Type  rpikit4  to decompress the files. Then run install.exe from inside
Windows.
http://www.zoomtel.com/files/rpikit4.exe 

Rockwell has released WinRPI version 2.26 (for WIN 3.1).
http://www.nb.rockwell.com/ref/rpi/wrpi_226.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 up-to-date and application specific (America 
OnLine etc.) information on its WWW site.
http://www.zoomtel.com/rpi_file.html

Rockwell has an unofficial list of DOS and Windows (that don't require 
WinRPI) communications programs that support RPI:
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/dcd/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 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 - 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.

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.

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

Before purchasing any modem, 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.
