Hi,
Thought it worthwhile to report for the benefit of all those struggling to make R-Connect work with Linux!
As I had reported earlier, the version 1.0 (beta) was not of much help. But the good news is it is irrelevant.
Go through the article (http://axion.physics.ubc.ca/ppp-linux.html) which gives step by step guidance of how to connect to your ISP (Reliance in this case) from a Linux box using pppd and chat.
I managed to make it work (after some tweaking here & there) with Fedora-Core-1 (kernel 2.4.22) and, btw, there is no problem with the linux driver as reported somewhere else.
I used a regular serial cable (not USB), but I guess it will also work with USB port as well.
If you would like to know about the details, please send me a Personal mail, based on the response I will put the relevant details on this site!
Good luck...
