Open a new root Xterm (if you are in X) or open a new virtual console and log in as root.
In this new session, issue the command
tail -f /var/log/messages
(or whatever your system log file is).
In the first window (or virtual console) issue the command
ppp-on &
(or whatever name you have called your edited version of /usr/sbin/ppp- on). If you do not put the script into the background by specifying & at the end of the command, you will not get your terminal prompt back until ppp exits (when the link terminates).
Now switch back to the window that is tracking your system log.
You will see something like the following (provided you specified -v to chat and -d to pppd)....this is the chat script and responses being logged to the system log file followed by the start up information for pppd :-

(Note - I am using STATIC IP numbers - hence my machine sent that to the PPP server - you won't see this if you are using DYNAMIC IP numbers.)
This looks OK - so test it out as before with pings to IP numbers and host names.
