Okay, so I got my ISDN line in.  Configured it using Slack's pppsetup. 
When I initiate the ppp-go script I get the following:

Serial connection established.
Using interface ppp0
Connect: ppp0 <--> /dev/ttuS0
LCP: timeout sending Config-Requests
Modem hangup
Connection terminated.


Any ideas?  Do I need to setup dial script, or should I try using CHAP
instead of PAP or something else?


Thanks.
