Re: [hylafax-users] Faxaddmodem with Mainpine IQ Express R3.2

Samuel,

The output you show below looks incorrect.  I have not seen it before 
and do not know exactly what went wrong.  That said, my first instinct 
is to suspect that your patching of the kernel did not do the trick.

Due to the infinite number of things that can go wrong and our inability 
to support all of that, as a matter of policy Mainpine does not advise 
kernel patching.  Instead, we advise customers to just use kernel 2.6.28 
or newer.  In some situations some customers refuse to (cannot?) follow 
this advice, and so we have provided the patches for those (hopefully 
rare) cases.

I fully acknowledge that not every distribution has updated to kernel 
2.6.28 or newer.  This may require you to change your preferred Linux 
distribution.  This may require you to use a "development" kernel in 
your distribution.

We went through a lot of effort to get the Rev3 patches into the 
mainstream kernel.  We did this because, as standard serial devices, we 
cannot provide a kernel module to realistically "replace" the running 
serial driver.  And because most distributions build the serial driver 
into the kernel itself (and not as a module) this really means that we 
would have had to provide a pre-built kernel for every distribution and 
version out there.  Instead, we chose to just get the patches into the 
mainstream kernel and to expect that the various distributions would 
update in time.

Meanwhile, in cases where the customer is unable to get to kernel 2.6.28 
on their own or where we are being asked to assist the customer in 
patching their old kernel it is our advice to the customer to simply 
install Fedora 9 and then install the pre-built kernel from here: 
http://mail.mainpine.com/files/.  As an alternative customers may choose 
to install Fedora 10 and use the "rawhide" or "development" kernel 
(which currently is 2.6.29, I think).  That said, I think that the SRPM 
on http://mail.mainpine.com/files/ should be able to be built and used 
on just about any RPM-based distribution.

Again, until your distribution of choice updates to kernel 2.6.28 or 
later the advice is to simply install Fedora 9 (x86) and use the 
provided pre-built kernel RPM.

Thanks,

Lee.
