Seems to be a never ending story.

slmodemd does not work with SuSE 11.4 "*-desktop" kernels, neither 64 nor 32 bit. Neither with precompiled nor with selfcompiled (in 32 bit) versions of slmodemd.  Reason seems to be SuSE's questionable hack with shorter timeslices, which tends to make the system react faster, but to work slower, see (sorry, found it only in german):

http://de.opensuse.org/SDB:Meldung_No_Carrier_mit_Winmodem-Treiber
http://de.opensuse.org/SDB:SuSE_Linux_9.0_/_Interaktivit%C3%A4t_ausgleichen

Deleted in SuSE 11.4 32 bit the *-desktop" kernel and installed instead the "*-default" kernel (in 64 bit not yet tested). 
slmodemd works now, the cryptic message "error: sched_setscheduler: Operation not permitted" disappeared. 

Now wvdial works, but browsing fails:

# wvdial

--> warning, no nameserver found `/etc/resolv.conf`
--> Nameserver (DNS) failure, the connection may not work.
--> Connected... Press Ctrl-C to disconnect

Yes, in wvdialconf is "Auto DNS = 1" 

(With "Auto DNS = 0" the two lines "primary DNS adress..." and "secondary DNS adress..." are missing).

Though this seems to be no more a modem problem, but a problem of pppd, I would appreciate some help.

Regards
Ludwig

Antonio,

yes, I did read the documentation contained in SLMODEMD_gcc4.5_alsa1.0.24.tar.gz :-))

Yes, I tried that Init2 string
Init2 = ATQ0 V1 E1 S0=0 X3 &C1 &D2 +MS90
and monitored the phone line with a voltmeter and high impedance (crystal) earphones. Same result: The modem takes up the phone and hangs it up immediately, doesn't dial.

Ludwig
