I have never been able to connect to BT Internet through Linux.
Works fine under Windows though, so I end up doing a majority of my surfing under that :(
Otherwise I use my Barrysworld dialup account (which is charged at Lo-call rates).
 
If anyone can give me any advice as to how to set up my ISDN connection to work with BT Internet then I would be *very* grateful.  BT's support for Linux is sadly lacking...
 
I have tried everythingTM and all I can get is a connection that allows me to go nowhere but makes the KISDN rate monitor go up to full all the time.
 
Regards,
