PCTEL modem on linux
These instructions are without any warranty at all. "Whatever can go wrong,
will go wrong..." (Murphy's Law)
This driver now includes support for 2.6 kernels when used with an pct789
and cm8738 type modems. The 2.6 driver does NOT yet support AC'97/AMR modems.
If you have an AMR/AC'97 type modem, 2.6 support may be possible through the
SmartLink driver. Releases rht-4c onwards still contain support for 2.4
kernels for all the three types of modem.
A number of issues have now been fixed in the rht-11 release which prevented the
driver compiling under kernel 2.6.32 and 2.6.34.
Important Note to 64-bit Users: This driver will NOT run on processors
running in 64-bit mode. The driver contains elements of pre-compiled 32-bit
components to which we do do not have the source. Unfortunately, this
situation is unlikely to change in the near future. If you wish to use your
modem from Linux, you will need to install a 32-bit version of your OS.
Important Note to Fedora Core 4 and 5 Users: There a couple of known
problem with this driver when used under Fedora Core 4 and 5, particularly when
using a Fedora compiled kernel.
Under FC4, after inserting the modules, the mouse will behave erratically and
will contine to do so until the machine is rebooted. This should now be fixed
in the rht-5 release.
Under both FC4 and FC5 using 2.6.13 and later kernels, the system may hang.
This should now be fixed in the rht-6 release.
