Update:
Installed an outdated version of the source
2.4.22 instead of 2.4.26 for DSL 0.8

After much searching I found a debian package for alien and its dependencies and converted the rpm package to a deb.

I got a spec file and a tar.gz file in the root directory
After I ran Make install
I got a bunch of unresolved symbols and an error.

[I]
But the most important thing is that it made a BCMSM.o file, I figuer this is the driver for the modem, and it took a bit of tweeking to get it to compile anyway.[I]

------------

OK after all this I realise that this is supposed to make a device ttySM* (I actually got it to make /dev/ttySMconfig) and put it as the device in ppp config but still no workie. If anyone has experience with making and installing drivers please share what you know. I think I am really close to having a linmodem
