IRQs of 0 or 255 are not functional!! The CPU cannot control the modem until this situation is corrected!! Possible corrections are: 1) Within the boot up BIOS, change from a Windows to a non-PNP/Other Operating System type. Instructions for accessing BIOS are at: http://linmodems.technion.ac.il/resources.html within: Additional Resourcces. 2a) Add an option "pci=routeirq" to the kernel boot up line. Here is an example paragraph from /boot/grub/menu.lst : title Ubuntu, kernel 2.6.15-26-686 root (hd0,6) kernel /boot/vmlinuz-2.6.15-26-686 root=/dev/hda7 ro pci=routeirq initrd /boot/initrd.img-2.6.15-26-686 savedefault 2b) Same as above, but use "pollirq" instead of "pci=routeirq". 3) Within some BIOS setups, IRQ assignments can be changed. 4) On non-laptop systems, moving the modem card to another slot has helped. 5) Sometimes upgrading the kernel changes IRQ assignment. ===================================== --- Bootup diagnostics for card in PCI slot 00:0e.0 ---- === Finished firmware and bootup diagnostics, next deducing cogent software. === Predictive diagnostics for card in bus 00:0e.0: Modem chipset detected on CLASS="Class 0780: 12b9:1007" NAME="Communication controller: 3Com Corp, Modem Division USR 56k Internal WinModem" SUBSYS=12b9:00c2 PCIDEV=12b9:1007 IRQ=255 IDENT=3COM.winmodem For candidate modem in: 00:0e.0 Class 0780: 12b9:1007 Communication controller: 3Com Corp, Modem Division USR 56k Internal WinModem Primary device ID: 12b9:1007 Support type needed or chipset: 3COM.winmodem Under Linux 2.6.n kernels, the chipset is NOT SUPPORTED .

The base of the UDEV device file system is: /dev/.udev Versions adequately match for the compiler installed: 4.2.3 and the compiler used in kernel assembly: 4.2.3 Minimal compiling resources appear complete: make utility - /usr/bin/make Compiler version 4.2 linuc_headers base folder /lib/modules/2.6.24-16-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 libc6-dev (and for Debian/Ubuntu, linux-libc-dev). 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: -rwsr-xr-- 1 root dip 269256 2007-10-04 14:57 /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) sudo chmod a+x /usr/sbin/pppd or under Ubuntu related Linuxes sudo chmod a+x /usr/sbin/pppd Checking settings of: /etc/ppp/options asyncmap 0 noauth crtscts lock hide-password modem proxyarp lcp-echo-interval 30 lcp-echo-failure 4 noipx 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 Read Modem/DOCs/YourSystem.txt concerning other COMM channels: eth0 Which can interfere with Browser naviagation.
