I don't know where the ^^M come from, here's my chat script

---begin
'ABORT' 'BUSY'
'ABORT' 'ERROR'
'ABORT' 'NO CARRIER'
'ABORT' 'NO DIALTONE'
'ABORT' 'Invalid Login'
'ABORT' 'Login incorrect'
'' 'ATZ'
'OK' 'ATB3'
'OK' 'ATDT0,0671700'
'CONNECT' ''
'TIMEOUT' '5'
---end
and my options
----begin
lock
modem
defaultroute
crtscts
user np95tc
noipdefault
ttyS0 115200
kdebug 3
----end

I forgot to tell you, but, in case it's important, I am using RH 6.0 out of
the box. I've just installed it.
Next, I will upgrade the necessary rpms and move on to linux 2.2.12, but I
think this should already be working.

Thanks,
Nuno

Why does your script send these ^^Ms? If I do this to my ISP it
drops dead.

This isn't very good; your chat-script is alarming because it's expecting
a ~ - and then timing out and sending two ^^Ms. You _should_ change this.

You're receiving a SIGTERM, and it's probably from the kernel ppp client
itself. It's hung 15 seconds, and what I think is happening is your chat
script is confusing the server or the other side, which wanted to start
ppp but got the ^^Ms. Eventually it gives up on you. What does kdebug 3
say?
