Here is the list that I have compiled since I joined this list a few
months ago.
Rockwell HCF V.90 code is broken. Won't handshake until you
set the
client side to use kFlex only. This is only a
workaround.
Needs latest Firmware to connect reliably. Get it
at:
http://www.zoltrix.com/MODEM.HTM#56,000 WinModems
Try AT+MS=3DK56
Any kind of line noise and it handshakes forever with
no connection
established. Client side says computer not answering
and client modem
hangs up during handshake.
USR 56k Will not handshake properly, slow data xfer when it does
Winmodem connect. Use S32=34 to disable X2 S13=64 to disable fast
retrains and download latest Firmware from:
www.usrobotics.com
AOpen 56k's Only one version of firmware, doesn't appear to
(FM56-P) help at all. Modem doesn't connect, same phasing
problem. Will
not handshake, rapid disconnection's (within secs
of establishing
a connection) a lot of the time, the modem will
just stop
responding.
Cirrus Logic Handshake/phasing problem. Similar to the AOpens.
Modem Will not connect. (chipset CL-MD56xx typically) Needs
latest
firmware 6.04 or later. If worse comes to worse, I've
been able to get the
Cirrus Logics to connect with this init string:
AT+MS=V34B,1,0,33600
http://www.gvc.ca/software/modems/ or
http://www.ambient.com/pages/drivers.html
CD04.08 - 604 PARALLEL (V.90-ONLY) SPEAKERPHONE
04 - DSP PATCH: 103.00
*NOTE* that the 4.08 is not the firmware number,
although it looks like
it. The 604 is actually the number you should look
at--that's 6.04.
Compaq 56-df LT WinModem in disguise. Go to:
ftp://ftp.compaq.com/pub/softpaq/sp9001-9500/sp9017.exe
To get the latest SoftPaq from Compaq or update it to
the latest LT WinModem drivers here
http://www.808hi.com/56k/x2-lucent.htm
*NOTE* Installing the LT WinModem drivers will make
the Voice
functionality of the modem not work with the Compaq
software on their
computer.
Compaq/Rockwell Livingston's web site says something
about put commas in and HCF modems force the modem
to connect no faster than 41.333.
Acer Aspire I was able to get one to connect by adding 3
commas after the Rockwell HCF phone number,
putting a 4th comma
caused it to not connect at all.
Update available from Acer ftp site:
ftp://ftp.acer.com/aac_support/desktop/drivers/modem/56KV90.exe
The 00-INDEX.TXT file says it is 2.1.1.110, but the
version information in the files is 2.1.2.110.
LT WinModems (use +MS=V32 for 14400 connections which seems to work
every time so far.) just long enough to download
the new drivers from
http://www.808hi.com/56k/x2-lucent.htm
They need 5.49 or later.
Kflex has been disabled in drivers v5.39+. to enable
K56flex instead of
V.90, then you must use s38=1-v90=0
USR Sportster V.90 Speaking from past experience, I too was using a
Sportster V.90
on a line incapable of supporting high V.90
connections. I would
connect around 48K but would soon drop off after a
minute or so.
By experimenting, I found that I could keep the
connection up
by setting a ceiling on the connect speed.
AT&F1&M5&N29&U28
Which sets:
&M5 (Error Control only)
&N29 44,000 Ceiling
&U28 42666 Floor
Diamond Supra AT&F1E0W2+MS=56 Forces it to KFlex which, for some
Express reason has a more reliable connection. Or is this
doesn't work try
AT&F1E0W2+ms=V34 for 33.6 speeds. Latest firmware is
important.
SupraMax modems Disable V.90, or update drivers at:
www.diamondmm.com/products/firmware/firmware-index.html
Motorola SM56 Firmware website:
http://www.motorola.com/networking/products/softmodem.html
%B18 should limit the modem to 33.6 and allow it to
connect
SoftK56 modem Firmware website:
chipsets
http://www.zoltrix.com/MODEM.HTM#56,000 WinModems
Look at the ATI responses for the individual modems
and match it with modem in question.
PCtel modem Firmware website:
chipsets
http://www.zoltrix.com/MODEM.HTM#56,000 WinModems
Look at the ATI responses for the individual modems
and match it with
modem in question.
Telepath Modems Telepath Modems in Gateways are usually USR
sometimes Winmodems.
http://www.gw2k.com/support/product/components/modem/index.html
ESS Modem Well, I got so frustrated with this fine fine POS,
I called the ESS
Tech for some info on their chip set. There ONLY
technician just told me
to use the 56KES-X2 drivers off of www.multiwave.com
and that the only
manual reference I need for their chipset is the one
for USR. Meaning it
is a bastardized USR chipset.
Shark V.80 56k Most of them use Motorola chipset. Since most
manufacturer uses the drivers straight from Motorola,
here the Motorola
URL for the modems and the drivers. Pay attention to
the different kind of
drivers with the identifier code.

Better Driver at www.sharkmm.com v90mot67-2.exe
Acer modems We've found that some internal Acer modems of this
vintage
(basically before Win95 shipped...) won't work reliably
with a port speed
of 115,200 - and the symptoms would often be strange
(connect, drop,
report no dialtone until a power cycle). When they did
n't weird out
they'd still disconnect frequently.
If the other end was an analog modem on a 57,600 serial
port they'd work
just fine, but calling anything capable of delivering
traffic above that speed
Try setting the user's port speed to 57,600. It works
for us
Xircom CreditCard Have him set S109=1, this will force K56Flex.
Modem 56T If still no luck, set S38=0, this will force V.34
Emachines/Etowers Interestingly enough, in this Tech Support FAQ on
their web site
http://www.e4me.com/techsupport/faq.html#modem
they claim that "When the UART speed of 8250 is
reported, this is
erroneous." Aparently they use a virtual UART, so we
now have a modem that
not only farms off the processing of signals, it also
doesn't even have a
real 16550 UART.
AT&F&C1&D2&K3W1 or ATN0S37=14 for V.90
N0S37=13 for K56Flex or N0S37=12 for V.34
Global Village dropped the customer to 38400 port speed and set them
to
CTS-only for the flow control (recommended to me by
Global Village)
Megahertz Cruise I have talked with Mac customers with
Card (33.6) Powerbook 1400s. In one case, they had
a Megahertz Cruise
Card (33.6), but were unable to connect to the digital
pool. Putting
commas after the access number in the settings seems
to work fine.
ATI0 = modem product code
"3 = modem firmware version
"6 = hardware info or link diagnostics
"7 = configuration screen (3Com/USR only)
"11 = specific information about modem operation
ATY11 = gives diagnostics for 3Com/USR modems.
