This post has been created for the little to medium experienced linux user to get the intel536ep internal modem working on Slackware 11.
Download the intel536ep driver from intel website download centre.
As root user extract the tarball to /root/intel_internal_modem_driver/ (create dir intel_internal_modem_driver)
At this point the install failed on my Slackware 11 system.
So, create a file named "modem_boot_sc" in directory /root/admin_scripts (create dir admin_script)
add this code to the file:
insmod -f /root/intel_internal_modem_driver/Intel-536/Intel536.o
mknod /dev/536ep c 240 1
ln -s /dev/536ep /dev/modem
Now make the file executable with:
chmod +x modem_boot_sc
Now add this to rc.local found in /etc/rc.d/
Reboot, and now the modem should work. Feel free to give feedback on this post.
Note 1, all directories and paths are "as is" on my system. Change to what you want but remember to change the script code to match.
Note 2, the driver/module "Intel536.o" is created if you have kernel 2.4.x. I believe kernel 2.6.x creates "Intel536.ko", therefore amend the script code above for your kernel.
Check your kernel with:
