Pradeep, Sorry, but I am not an Ubuntu expert, but I will try to relate what scanModem reports to us. You need hsfmodem drivers: Predictive diagnostics for card in bus 01:06.0: Modem chipset detected on NAME="Communication controller: Conexant Systems, Inc. Conexant SoftK56 Data/Fax Modem " CLASS=0780 PCIDEV=14f1:2f50 SUBSYS=14f1:205f IRQ=5 IDENT=hsfmodem Driver=hsfmodem-drivers For candidate modem in: 01:06.0 0780 Communication controller: Conexant Systems, Inc. Conexant SoftK56 Data/Fax Modem Primary device ID: 14f1:2f50 Support type needed or chipset: hsfmodem For owners of a Dell PCs with Conexant HSF modems, a driver source package with full speed enabled is available, but requires driver compiling. Read DOCs/Conexant.txt Support for the 14f1:2f50 and 14f1:2215 HSF modems is projected early in 2007 from Linuxant. From http://www.linuxant.com/drivers/hsf/full/downloads-ubuntu-x86.php download hsfmodem-7.80.02.02full_k2.6.28_15_generic_ubuntu_i386.deb.zip Under Linux unpack with: $ unzip hsfmodem*.zip Then install with: $ sudo dpkg -i hsfmodem*.deb Subsequently, the modem should be found with $ sudo wvdialconf /etc/wvdial.conf Edit in your personal information with: $ sudo gedit /etc/wvdial.conf and try dialing out with: $ sudo wvdial. See DOCs/Testing.txt for details. Since your distro is 64 bit you may need to compile your own drivers, and take a carefull look at this part: Minimal compiling resources appear complete: make utility - /usr/bin/make Compiler version 4.3 linuc_headers base folder /lib/modules/2.6.28-15-generic/build However some compilations and executable functions may need additional files, in the FileNames.h (so called kernel "h"eaders) collection installed in /usr/include/ . For martian_modem, additional required packages are needed. The also required headers of package libc6 are commonly installed by default. Compiling hsfmodem drivers does require linux-libc-dev and libc6-dev packages, for kernels 2.6.24 and later versions. In not included on your install CD, search for them at http://packages.ubuntu.com or comparable Repository for other Linux distros. When compiling ALSA drivers, the utility "patch" will also be needed. Regards, Antonio On Tue, Sep 15, 2009 at 12:32 PM, Pradeep K.
