[expert] I have an interesting problem

[Lord And Master;)]

I switched isp's yesterday and after setting up the information in
chat-ppp0 it dialed and then was imeditly disconnected, I looked in
/var/log/messesges and it says that it had received invalid login. But
when I log into the server with minicom and type in the same user name
and password that are in the chat script all is fine. What gives?
everything worked fine with the old isp!
