So far, I've only updated the code to work on 2.6.29.*. It does
include an update that should work on 2.6.31, but I don't have that
kernel to test it.

The driver works well on 2.6.29.6. I've currently been connected for
over 2 weeks, at 53666 baud.

I'll have to wait and see about later versions when the next
Slackware release comes out. This machine unfortunately cannot be
taken down for testing, only major upgrades.

You've mentioned several kernel versions. Which version do you normally use?

The struct uart_info in the kernel changed a bit around that time. Use
an older code package for older kernels. The driver has only been
updated to follow the kernel changes, there are no functionality
updates.

This link is to an older version, which I think should work on that
kernel. It's source only and not dkms capable, so you'll have to
compile and install manually. Always make sure to remove old modules
before installing new ones.

Marv, Jacques: I notice newer 048c/f packages are going in the
11c11040 directory instead of sv92. Why is that?

This is not needed unless there is an IRQ conflict. Run 'lspci -v', to
check that. Or send us the output of scanModem so we can check it.

The 11c1:048c/f is on a stand-alone PCI card and is not part of the
sound device, as more recent Agere modems have been. So this driver
does not use ALSA, and ALSA doesn't know anything about this modem.
