This has nothing to do with interrrupts. The problem here is that ppp is
not started on remote side and still trying to communicate with you via
human-readable ascii (that's the origin of 8-bit unclean). Try to connect
to the peer using minicom, login mannualy and start ppp by either typing
"ppp" or something like that. When you see garbage on the screen - you are
done! Just remember what you did and edit your /etc/ppp.chatscript
