Ran scanModem, Agere LT modem, compiled martian-full-20080407 as recommended (2.6.18 kernel, so it said to use this, not a newer version). Everything seemed to go fine until first run of wvdial, which produced the following: (Further below are the output of demsg after the crash, output of the compile and install, and finally ModemData.txt.) Help?!?

The base of the UDEV device file system is: /dev/.udev.tdb Versions adequately match for the compiler installed: 3.4.5 and the compiler used in kernel assembly: 3.4.5 Minimal compiling resources appear complete: make utility - /usr/bin/make Compiler version 3.4 linuc_headers base folder /lib/modules/2.6.18.1/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. If a driver compilation fails, with message including some lack of some FileName.h (stdio.h for example), then Some additional kernel-header files need installation to /usr/include. The minimal additional packages are libc6-dev and any of its dependents, under Ubuntu linux-libc-dev If an alternate ethernet connection is available, $ apt-get update $ apt-get -s install linux-kernel-devel will install needed packages. For Debian/Ubuntu related distributions, run the following command to display the needed package list: Otherwise packages have to be found through http://packages.ubuntu.com Once downloaded and transferred into a Linux partition, they can be installed alltogether with: $ sudo dpkg -i *.deb Checking pppd properties: -r-xr-xr-x 1 root root 250996 Feb 21 2005 /usr/sbin/pppd In case of an "error 17" "serial loopback" problem, see: http://linmodems.technion.ac.il/linmodems/archive-sixth/msg02637.html To enable dialout without Root permission do: $ su - root (not for Ubuntu) chmod a+x /usr/sbin/pppd or under Ubuntu related Linuxes chmod a+x /usr/sbin/pppd Checking settings of: /etc/ppp/options lock In case of a message like: Warning: Could not modify /etc/ppp/pap-secrets: Permission denied see http://linmodems.technion.ac.il/bigarch/archive-sixth/msg04656.html For guidance on FAX usage, get from http://linmodems.technion.ac.il/packages/ get faxing.tar.gz It has samples for a modem using port /dev/ttySL0, which must be changed to match your modem's port.
