I understand that a number of folks have gotten the US Robotics 5610 PCI hardware modem to work.

XP on the same box detects the device fine, and says it uses irq 23 and is at 0xc800. It configures
com3 to be the modem.

lspci on Knoppix shows irq 5 and the same address.

I've tried using setserial to configure the serial port, and kppp (Query modem...), pppconfig and
minicom to try to connect to the modem, with no luck. My setserial command looks something like:

setserial /dev/ttyS4 port 0xc800 irq 5 uart 16550A

I've tried irq 5 and 23, and ttyS4 and S7, all with no results. setserial -g shows the change, but
kppp and minicom fail to connect to the device. pppconfig hangs while probing the device.


Any clues?

Thanks!
