modem+kppp question..

[Ishwar Rattan <ishwar@pali.cps.cmich.edu>]

I am trying to connect to scholl dial-up via USRModem and Kppp.
I configure the modem (including initialize string), but when
dialed it gets connected to remote box, the message is displayed but
stays stuck at:

host:
(in log window) but expecting CONNECT string from remote box.
The remote box (school) uses PAP/CHAP with prompts

host: ppp
login: <my-username>
password:<my-password>

I tried it through terminal window (interactively), connects, ppp is
set up (garbage chars seen) but I couldn't find a way to close window and
put the connection in background (modem hangs up on closing the window).

Any pointers?
