I have tried Wavecom website, unfortunately I could not go further as I was asked for a password. Apparently when their product is purchased, the buyer will be given a ID and Password. Well, I do not have such things (NO, I didn't steal the modem!)
In their FAQ, Wavecom mentioned that the Modem is compatible with many OSes, I presumed that this modem will work fine in Linux using standard drivers?. In Windows, the modem ran fine using the Standard modem drivers.
Anyone can teach me how to install this modem in Linux RH9?
