hi,every kind of modem has different AT commands to initialize itself. For
example,TP-LINK TM-IP5600 56K Modem has two special initializing AT
commands.One is AT&F&D2&C1V1S0=0E0 and the other is
ATS7=60\T0L0M1\N7%C1\Q3*LS1X4. The first one is executed by DTE when the
modem needs to be initialized. The latter is used after AT+FClass = x is
executed (on the case of sending fax).My question is that how can I get
those AT commands to initialize certain kinds of modems? Any advice will be
really appreciated.

Best Regards

Crespo

The two strings are probably found at these registry keys:

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Class\Modem\000n\Init
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Class\Modem\000n\Settings\Init

They are taken from the appropriate INF file for that particular
modem. This INF file would be included with the drivers.

What in particular are you trying to do?

Loaded a new driver for Zoom 3025N after that and alot of misspent
effort I still have a problem where now I dont get the MODEM LINE speed.
Not sure if it DUN or what the hect. I looked in the registers you gave
above and I find odd things. My modem is on com3. please note below.

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Class\Modem\0000\Init

(default) (value nt set)
ab1 "AT<cr>"
ab2 "AT& FEO &C1&D2V1 S0=0\V<CR>

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Class\Modem\0000\Settings
ab (Default) {Value not set)
ab1 "ATS7=60S30+30L0M1\N3%C1&K3B0B15B2N1\J1|
ab2 "ATX4|"
ab3 "ATS7+MS=V90|"

ab3 I put in just afew minutes ago to get faster connect speed from
Earthlink since they do support V92. Since I only have one internal
modem on Comm 3 I am puzzled with the above and couls that be the
reason I am noy getting connection line Speed.

If the INF file for your modem is broken (as is sometimes the case
with V.92 modems), then it may not contain all the CONNECT responses
that the modem is capable of producing. Check the modemlog for any
CONNECT messages. If a corresponding CONNECT string does not exist in
your INF file, then the modem will not know how to decode it and will
instead revert to reporting the port rate.

Check the Responses at this registry key:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Class\Modem\000n\Responses

The name of your modem's INF file is recorded in the InfPath parameter
at this key:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Class\Modem\000n

See also "Windows Modemlog can help locate trouble":
http://www.modemsite.com/56k/modemlog.asp

"What to do if you get a CONNECT 38.4, 57.6, or 115.2k":
http://www.modemsite.com/56k/x2-inf1.asp

If you find that the appropriate CONNECT responses are missing, then
it is relatively straightforward to add them to your registry. Let me
know if this is your problem.
