I cannot get it to run with Knoppix 3.2. I have a HD install.

lspci -v looks like this
000:0b.0 Serial controller US Robotics/3Com 56K Fax/Modem Model 5610 (rev 01) (prog-if 02 [16550])
Subsystem:USR/3Com= Unknown device 00d3
Flags: medium devsel, IRQ 9
I/O ports at ec00 [size= 8]
Capabilities: <available only to root>

this is the response I get from wvdial:
--> Initializing modem.
--> Sending ATZ
ATZ OK
--> Sending: ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
OK
--> Modem initialized
-->Sending ATDT (ISPs #)
<hear dial tone>
<doesn't dial>

cd/dev
chmod 777 modem
chmod 777 ttyS4
links and devices are therealready
doesn't do anything

Any ideas as to what to do to get it to work?
