WinModem - Modem, usually PCI, which relies on the host computer for it's processing power. Most often these modems only work in Windows with the modem drivers. However increasingly there are more drivers available for Linux, so these modems get affectionately called "LinModems?". Beware tho, not many modems are fully supported under Linux. Intel now has such a chip (DSE sells modems based on these) and because they have both windows and linux drivers Intel calls them HaM1? - Host-Accelerated Modem. Another example is the mwave winmodem in IBM thinkpads - IBM has released a GPL linux driver, which is now in the main kernel.

By far the most common WinModems (at least in New Zealand) are ones based on Conexant chipsets. For a long time there was no way at all to get any of these to work in Linux. At some point after I (SamJansen) needed Conexant modem support for Linux they released Linux drivers. The first place to stop if you have a WinModem is probably:

If you want to get a new modem for a linux machine, and you're faced with a WinModem or an expensive external serial modem, then try to get one with a Lucent or Agere compatable chipset. I just installed a Lectron I56LVP/F4 ($32 at this point - May 2004) in a machine, and it runs fine with the ltmodem drivers ( Try the binary package first, but the ones for FC1 wouldn't work at all for me. Get the source package and follow the instructions, there's a couple of scripts you can run which basically automate the whole installation

1? I have seen modems branded as HaM around for a long time. In fact, the first ever WinModem I saw was an ISA 33k6 HaM. This was in pentium class machine, and was purchased with the machine. HaM is just the generic term for WinModem.

(I always understood that HaM was an acronym for "Host assisted Modem.". Googlefight says I'm wrong :) I don't quite see how a 56K winmodem is 'accelerated' in comparison to a 56k hardware modem, I guess it's one of those marketing terms.. - zcat)
