I would just like to add that there is a very nice encore (Intel) modem for $10 that has redhat source, and and RPM in a driver package. Not to mention that they also have BSD drivers etc... I bought about 6 of these modems for remote windows users, and our Linux fax server. The modems are rock solid, and like I said they work flawlessly with Linux, and the drivers are written by Intel so you know they are very effective. Here is the link to a good buy. The one that I own a lot of is the $10 one on the page.

BTW I wanted to just let you know that, I know you can not use this modem in your case (laptop) I was just simply suggesting this for others looking for modems packages etc...
