Help: NO DIALTONE on lucent winmodem

[Miku]

Hi,
I have been masochistically attempting to get my lucent winmodem working with a HD install of Knoppix 3.3/4 (I believe it is a prerelease version of 3.4, more similar to 3.3 than anything else).

I have read funkea's advice in the thread: http://www.knoppix.net/forum/viewtopic.php?t=2050 but am still having problems.

I have done the following:
1) Downloaded and unzipped ltmodem-8.26a9.tar.gz into /tmp
2) Run ./build_module, then recompiled the source using gcc-2.95 when I got complaints about the gcc version.
3) Performed the commands:
mknod /dev/ttyLT0 c 62 64
chmod a+rw /dev/ttyLT0
ln -sf /dev/ttyLT0 /dev/modem
insmod -f lt_modem.o
insmod -f lt_serial.o

Everything seems to work OK, and when I run KPPP and attempt to connect the log window even displays the correct commands and responses to/from the modem: ie: "ATZ / OK" etc.

However, after the actual dial attempt (ie "ATDT12345678"), it always comes back with a NO DIALTONE response, and there is no evidence that the modem was used at all.

So, questions:
1) Are the responses from the modem script generated by the modem itself, or the drivers that I installed? (in which case there is no evidence that the modem has been detected or used at all).
2) How do I get it to work?


(Supporting info - scanmodem provided the following output
11c1:048c PCI bus PCI_ID with vendor component: 11c1
11c1:044c and Subsystem PCI_ID with vendor: 11c1

Thanks for any help.

The response (OK) is from the modem.
And 'no dialtone' too. Else you get an answer like 'no modem found'.

In the kppp - configuration, there is a section modem/ query modem where you may test it too.

Unfortunately I cannot help you any further.

Thanks for that, at least I know that the modem is semi-usable.

Query Modem works fine for /dev/modem.

The modem itself is actually an Agere winmodem, but I was informed that the lucent drivers should work with it. Query Modem returns text identifying it as an ltmodem, which made me suspicious that possibly the text was being returned by the drivers I installed and not the modem itself.

The NO DIALTONE response remains a mystery.

OK, so here is my last attempt to get this working!

I haev compiled all the info I can get my greedy mits on, for the viewing pleasure of anyone who thinks they might be able to help.

For starters, the driver package I downloaded was ltmodem-8.26a9.tar.gz

Query Modem in kppp returns:

ATI : V.92 Data+Fax Modem Version 8.26a
ATI1: 00
ATI2:
ATI3: V.92 Data+Fax Modem Version 8.26a
ATI4: 0
ATI5: 8.26a,0,19,11C1,0440,11C1,044C

When I attempt to dial, the log window in kppp displays:

ATZ
OK
ATM1L3
OK
ATDT82109044
NO DIALTONE

I run the following script to set up the modem:

 cd /home/knoppix/tmp
 mknod /dev/ttyLT0 c 62 64
 chmod a+rw /dev/ttyLT0
 ln -sf /dev/ttyLT0 /dev/modem
 insmod -f lt_modem.o
 insmod -f lt_serial.o

I have set up /etc/modules.conf as follows to try and fix it, with no luck:

options lt_modem vendor_id=0x11c1 device_id=0x048c
options lt_modem Forced=10,0x02000,0x020ff,0

and finally, the setserial and /proc/interrupts report:

#setserial -agv /dev/modem

(I believe es1371 is the modem, as it appears to double as the Ensoniq soundcard)

So.... can anyone shed any more light on my problem?

[ktheking]

I think you should insert some AT commands about your country origine.
Indeed ,phone electrical properties may differ from country to country .
With this string you tell the modem to search and wtach the phone line entrance for a certain voltage (for example 24V to 48V for Belgium).
Even on some windrivers with some winmodems this phenomena occurs and you have the add supplementary initialisation strings.

Hope this'll help ...

And you could try to rmmod the sound-modules, while using the modem, when it claims the same IRQ.

Hi again,
I did some mild tinkering with modem initialisation as well, but it was alot of groping-in-the-dark type stuff.
I have also tried removing the sound module, but met with no success.

I think this one is getting filed under "W" for "winmodems suck".

I have since received a shiny new external modem which was detected immediately and worked first time.
