need help with ppp

[KHOO Guan_Chen]

Sorry for using up bandwidth.

I cannot connect to my ISP with FreeBSD (6.0). The ISP is not using 
PAP/CHAP in my case, but apparently something very old. Using minicom 
I can see that
1. my modem is connected to /dev/cuad0
2. after i dailled the ISP, they put me through a login. password and 
a local phase ie.after atdt<ISP phone_nbr> \r, I see:-
connect 115200
Login: <my user_id> \r
Password: <my_password> \r
Local>
  I have tried to enter things like "ppp", "~ppp" "cppp" ">ppp" after 
the (Local>) in my chat_script
but  no go. In minicom, I see that they sometimes drop me into a 
shell to which I can only exit,

Could someone give me a few more hints or the correct string to enter? please.

Oh my ISP help is no use. They replied to my request with sorry we 
cannot help you (because)
"We at Technical Helpdesk are trained to support Windows and Mac 
based platforms. Your kind understanding is greatly appreciated." ARRRRRRGH  !!

Thanks alot
