-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 HaM[1] - 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
.

WinModem is an overglorified SoundCard masking as a MoDem. The device itself has little else than a [DAC]/[ADC]
, and the actual signal processing logic is rolled off to
the host computer's [CPU], where it is hidden inside a "driver"
. Manufacturers usually write such drivers
only for [
Windows]
. Fortunately
there are increasingly
more WinModem
drivers available for [
Linux]. Such [MoDem]s
get affectionately called [
LinModems | http://www
.linmodems
.org/
]. Beware though
, there are only few of these among
the winmodems
.
-By far the most common
[WinModem]s (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: [http://www.linuxant.com/drivers/]
.
+[Intel] now has a supported
WinModem chipset ([DSE
] sells modems

they have both [Windows] and [
Linux]
drivers [Intel] calls them HaM (Host-accelerated Modem)
. How
a 56K
WinModem is "accelerated" in comparison to a 56k hardware modem isn't entirely clear; this appears to be MarkeTroid speak
.

+The MWave WinModem in [IBM] [ThinkPad]s is also supported
. IBM released the driver under [GPL], so it has made its way into the official [Kernel] source tree
.

-[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
.
+If you want to get a new MoDem
for a Linux and would like to avoid
the cost of a hardware MoDem, DanielLawson recommends a Lucent or Agere compatible chipset based
WinModem, after good experience with a Lectron I56LVP/F4 ($32 as of May 2004) that runs fine
with the [ltmodem drivers | http://www
.physcip.uni-stuttgart.de/heby/ltmodem/]. If
the binary package doesn't work
for you, get the source package and follow the instructions, there's a couple of scripts you can run which basically automate the whole installation
.
+
+Some modern distros include drivers for the more common winmodems.
