ActionTec Internal PCI Call Waiting Modem - PROBLEM!
I am having the exact problem as mentioned in Topic http://www.linuxforums.org/forum/top...lwaiting+modem
I posted there, but so far no replies.
The person there who started the post got it working, but ALAS, did not tell the forum what he did to get it working.
See the other page mentioned above to see what I've done please and what was suggested by Dapper Dan.
One thing that I've done since my last using Linux is that I used the firmware flash to v.90 for the modem. I'll bet this is why it doesn't get picked up, but I'm not so sure.

Actiontec Internal PCI Call Waiting Modem and kernel 2.6
The problem is (mostly) in the 2.6 kernel configuration. You can easily recognize the distributions that will support this modem by doing
dmesg | grep ttyS
If you can see ttyS14 there, you have a chance. If not, then you need to recompile the kernel. From the distributions I tried Suse 9.1 and Kubuntu 5.04 do it right. Knoppix 3.4, 3.6 and 3.7, Mepis 3.3.1 test1 and Kanotix do not.
I managed to get the modem working on Knoppix 3.4 by compiling kernel 2.6.11 and enabling support for more than 4 serial ports there.
However, the same kernel didn't get the modem to work on Kanotix, so I guess this is not always the full solution.
I think it is rather stupid not to enable support for more than 4 serial ports. It saves at most several hundred bytes of memory, but leaves the internal modem owners without support for their hardware.
This problem is not present with 2.4 kernels. The modem is assigned /dev/ttyS4 there.
