If you have a PcTEL modem, you have a pretty good chance of getting it to work for linux i know that for sure. If you have one post a reply and ill dig out a link. Or you can do a search for "Jan's Pctel Resources" and that should give you a good link to his/her site.

Ok I feel compelled to comment now....anything you can do in software you can do faster in hardware....this is a basic rule in DataCommunications.....just ask your favorite router or switch. The real modem is faster than ANY win modem because the winmodem has replaced hardware with software...this despite the fact that the trend in DataCom is in the other direction.
Please do yourself a favour and get a real modem.

I can offer a perfect example of this which has just happened to me. The old IG (Interent Gateway ) had a USR 56K internal modem and it worked great. When I upgraded my old machine became the IG and the IG went to the kids. I could not use the USR internal in the new IG because it is a 16 bit card and the new IG has only PCI slots. So since I upgraded we have used PCTel crap winmodem that is onboard in the new IG. We had alot of problems with losing connections and extremely slow access. So I went to ebay and bought a USR External 56K. I recieved the USR external today and instantly the problems disappeared.
The damnedest part is the used USR external modem only cost me $20 USD. So I went for like a month accessing the web on that piece of crap winmodem. Still kicking myself in the ass over that one. Shit it was only 20 bucks.

I don't believe a router would necessarily be the best example. Routers (Cisco/Bay etc) are really nothing more than a computer running an operating system (IOS) and usually boot their operating system from a flash card (they can also boot from TFTP etc). The real advantage of a Cisco router is you can put boat loads of interfaces in the bigger routers and the OS is designed specifically for routing, not much more. In fact I believe the Cisco IOS is derived from a UNIX kernel and custom built commands for routing (I am embarassed that I don't know for sure without doing a search as I should know this). Other *NIX OSes can do a very good job of routing although they may not support all of the routing protocols (EIGRP etc). QOS is something that is included with later kernels along with kernel level access rules. And if you happen to have the source code for said kernel you can trim out all of the non-routing related fat and it performs very well. Large Cisco routers are certainly more robust but you pay for it too. The real advantage of a conventional (hardware if you will) router or firewall is reliability. Not OS reliability but hardware reliability. Since their intended purposes are specific you don't need unreliable devices installed such as hard drives, video cards etc.
The modem is a better example. Hardware modem for sure is a wise choice.
