with the above info (gathered from your computer) use the following tips to make KPPP work [assuming a hard drive install of knoppix]:

setserial -v /dev/ttyS4 uart 16550A port 0xa000 irq 5

add above line to:
/etc/init.d/setserial

where do put this?
ln -s /dev/ttyS4 /dev/modem
these two lines seem to work in .login
suassword
ln -s /dev/ttyS4 /dev/modem

in KPPP choose /dev/modem and voila, KPPP will now dial your ISP




notes below are for ppp via console:

cd /etc

wvdialconf [auto creation of wvdial.conf]

/etc/wvdial.conf

sample wvdial.conf follows:

[Dialer Defaults]
Modem = /dev/ttyS4
Baud = 57600
Init = ATZ
Init2 = AT S11=50
Phone = xxx-xxxx
Username = xxxxxxx
Password = xxxxxxx

[Dialer phone2]
Phone = 555-4243

[Dialer shh]
Init3 = ATM0

[Dialer pulse]
Dial Command = ATDP



after your wvdial.conf is set type "wvdial"
