wvdial, gnome-ppp and all the other required apps are in the DVD edition of LM13.
I would expect them to also be in LM14 DVD edition - but I havent checked this myself.
Advice that suggests to "download these apps from the online repositories", when you are not online with *that* machine is a bit of a Catch 22.
This link below, has instructions to install dialup apps from the LM13 DVD clean install.viewtopic.php?f=157&t=115291&p=661532&hilit=dialup#p661532
Be aware however, that this instruction set is for External Serial Dialup modem, 56k, connected to Com1 port on computer. This arrangement works.
You have indicated that you have various PCI modems that you want to connect.
The dialup suite of apps I refer you to here (link above) in the LM13 DVD edition, may not
help you with your hardware arrangement.
As I understand it, the PCI modems still need drivers to be downloaded/built/installed, to suite your Linux installation, and your modem. A few ppl have noted (as I have also found out), that to make a modem driver requires you to rebuild your Linux kernel. It seems that the LM DVD edition does not have the necessary packages to enable a kernel rebuild, and so you have to walk files from your connected machine, back to the Linux machine you are trying to get connected.
Regarding your Smart USB 56k modem, you *also* may, or may not, have to do something to get Gnome PPP software to see your USB port as a usable serial port. In my installation, my Gnome-PPP *does* see the 4 USB ports alongside the serial ports, (whether they are properly usable or not, I do not know, I haven't checked), but in other Linux distros, MacPup, Ubuntu, for instance, the USB ports are not even seen by the dialup apps there.
In my internet browsing, I also found a much older post elsewhere, that the Linuxant modem drivers, for Conexant hsf/hcf/etc modems, simply do not work (refuse to be built) past Linux kernel 2.6-ish. Something to do with changes in the kernel. This post was dated somewhere around 2007-8, when this connexn problem was probably first discovered.
If anyone can correct me and can also post an instruction set for the OP problem, *please do*, as the OP has a problem which is similar to my current task; to get a Conexant USB 56k modem connected.
My reason to find a solution is because...
- if you still have, or can only use dialup,
- and serial ports are fazed out on newer hardware, and while
- some current and future Linux distros support the dialup process in software, but,
- there is no support for current computer hardware (ports and external devices),
- and your old computer hardware then dies, then
- you're stuffed.
