Actiontec 560LKA serial port modem
I have used this particular modem many times with mandriva, fedora, Kanotix, Mepis, PCLOS, SAM linux.
Kppp does all configuration. just enter login name and password. Set device to ttyS0, lower connect speed to 57k and this thing works everytime. I have noticed that in general if modem query in kppp returns no info then there is trouble but so far not with this modem.....but back to 5.8 and wvdial...
I don't think this is a modem problem as wvdial continues to show ttyS0,1,2,3 are all busy, with or without the modem connected and/or turned on.
I have setserial /dev/ttyS0 as root and output shows what appears to be device configured using IRQ4 which is all by itself. Graphics USB, etc are all IRQ 3,5,11. Also, there do not seem to be any settings in BIOS to select plug n play or auto select. Although I can select some IRQ settings, Im wondering if during install, VL grabbed IRQ needed by serial to use somewhere else. OR....
I'm wondering if the serial port is damaged on this PC. THis is the first time I'v had this much trouble.
hope this helps
