Problem with external serial modem
 

I got a 3Com U.S. Robotics external serial modem. I am trying to set it up. I did:
knoppix@box:~$ echo atdt3333333 > /dev/ttyS0
The modem lights starts flashing but kppp does not recognize it. I did:
knoppix@box:~$ setserial /dev/ttyS0
/dev/ttyS0, UART: 16550A, Port: 0x03f8, IRQ: 4

Any idea?

man wvdial

Thank. I will try.
