SERIAL PORTS in KNOPPIX 641

John-Paul Stewart

Preface; I have a USR PCI 56K Modem as well installed on one machine here - but I use Ethernet through the installed NIC...so I don't use the modem while booted into Debian 3.1r1, nor have I had to set the modem up for use under linux (dual boot win98 box).

FWIW - I've saved a KNOPPIX v3.6 bootupetc-inittab output - for comparison to Debian when I was comparing the *default* runlevels (Knoppix=runlevel5 -- Debian=runlevel2).

There's some info listed within which may prove useful for setting up Modems-Serials-Gettys;

I don't have much linux configuring experience, so perhaps others here can follow-up using any-some of the info I've posted.

That said; once you get it up and running ok - you would likely want to use the "Save KNOPPIX configuration settings" option - found in "Utilities"....more info about all that;
